While I was on the highway driving with my daughter in the car with me the steering wheel detached mid drive on the highway I am so thankful there was no one behind me in front of me, but I couldn’t turn. I couldn’t even properly move. I had to call the cops so they could safely help me get out of this situation. This not only affected me. It could’ve been a hazard to everyone around me it could’ve been a hazard to me and my daughter that was inside the vehicle. What irritates me the most about the situation is because I have went and got the same issue service by Tesla and then they said that it was repaired and that this issue was solved and now the same exact thing happened again and now they’re asking me to pay 8000 to repair this issue that they claim they apparently already resolved. Why would I pay 8000 for an issue that is happening multiple times and I’m not doing anything to cause this. It just keeps happening. The car is clearly unsafe. and there was nothing to have warned me that this was gonna happen. I was just driving on the highway no warning message no prior issues prepared me for this. It just detached the whole steering wheel detached. From my research it is a common issue that keeps happening with all Teslas no matter what model in year it keeps happening so it’s a Tesla issue.

Tesla's Full Self Driving does not allow the operator to choose a maximum, never-exceed speed. If the perceived speed limit is wrong, which happens often, the ADAS becomes very dangerous driving much too fast.
- Forward collision avoidance › Adaptive cruise control
Vehicle was driving on "supervised full self driving" mode westbound on Braddock Rd at 3:50pm near Willow Springs Elementary school. Posted speed limit on Braddock Rd is 45mph but there was an active 25mph school zone limitation at that time, indicated via flashing speed limit sign. Vehicle ignored the sign and traveled at 38mph through the entire school zone.

I am reporting a suspected defect in the rear Large Drive Unit (LDU) of my vehicle, a 2017 Tesla Model S P100D with approximately 40,815 miles. The component involved is the rear drive unit’s rotor seal, which is known to allow engine coolant to leak into the motor. The concern is safety-related. Tesla coolant is electrically conductive and can form a conduction path inside the motor and inverter, and coolant can also damage bearings. Once coolant enters the drive unit, the result can be electrical faults, loss of drive power. If the drive unit fails while the vehicle is moving, especially at highway speeds, it could cause a sudden loss of propulsion or reduced braking-related regeneration, which could lead to a crash. Other owners have reported this kind of failure without warning. I am concerned about both the loss of propulsion and the electrical hazard of coolant in high-voltage components. I have not had a drive unit failure. I have received a quote of approximately $1,500 from an independent shop to apply a preventive coolant bypass in which I am not confident that an aftermarket bypass will fully prevent the failure, and I have not seen independent long-term data on its results. I have was told that a drive unit replacement, if the leak progresses, could cost $5,000 or more. A Tesla service advisor told me on earlier in 2026 when they inspected my Tesla that Tesla will only address this issue if the drive unit has already failed, and that there is no preventive repair available for vehicles that have not failed. I believe this is a design defect in the rear Large Drive Unit. Tesla has replaced failed units under warranty with a revised “U” drive unit that blocks coolant from entering the rotor. I request that NHTSA investigate whether the original rotor seal design is a safety defect and whether the revised design should be offered to owners of affected vehicles, including those whose drive units have not yet failed.

The new defects with audible chimes and safety alerts are a direct consequence of the 8GB eMMC safety recall service performed by Tesla my car is now not warning me with any chimes or sounds related with safety features of the car. Tesla are attempting to charge me to correct safety defects introduced by Tesla's own recall repair. Confirmation that Tesla refuses to repair the new, service-induced safety defects at no cost. My concern is that I brought the vehicle to Tesla fully functional and drivable, and immediately following the 8GB eMMC recall service, the vehicle became undrivable due to the infotainment computer failure. Since this occurred immediately following a Tesla-performed recall procedure, I am asking that Tesla take responsibility for resolving the issue rather than having me incur the cost of replacing the computer.

While using Tesla's Actually Smart Summon feature via the phone app in a hospital parking garage, my unoccupied 2017 Model S initiated an unexpected turning maneuver and struck a clearly visible parked SUV (a 2019 Toyota RAV4). I was within line of sight and actively supervising per Tesla's instructions, but the vehicle turned into the parked car without any meaningful opportunity to intervene before impact. The failure appears to involve the Summon system's object detection, path planning, or control logic. The incident occurred at low speed. Both vehicles sustained property damage; there were no injuries. The vehicle's own cameras captured the entire incident; full video is available on request and still frames are attached. I reported the incident to my local Tesla service center the same day; no investigation was performed. On 3/13/2026 I formally requested all data associated with my vehicle for the day of the incident, specifically including moment-by-moment vehicle system data: Summon session logs and command history, telemetry and event data recorder data, sensor and object detection outputs, and path planning/control decision data. Tesla provided only basic account-level data and did NOT provide any of the requested vehicle-level event data. A formal notice of defect and evidence preservation demand sent to Tesla Legal on 5/2/2026 received only automated replies. Although I have contacted Tesla many times by phone and email since the incident (first written claim 3/30/2026 went unanswered), Tesla has refused to follow up: apart from two brief emails from a corporate case representative on 5/4/2026 and 5/11/2026, my litigation hold and data preservation requests and all subsequent emails and calls have received no response. The vehicle remains unrepaired and available for inspection. My insurer has paid the other party's property damage claim.

Backing out of driveway, the steering wheel was very hard to turn. The dash indicated the steering assist feature wasn't working. After restarting the software and the problem persisting, I investigated the assist motor/pump and found that the ground to the chassis was very corroded. I attempted to remove the nut to clean contacts and it sheared off. The grounding post had corroded through (white galvanic corrosion). I attached the assist motor ground to another point on the chassis and the power steering worked again.

2017 Tesla Model S P100D. Vehicle received a paid MCU2 infotainment upgrade (MCU1 to MCU2), which replaced both the center touchscreen computer and the instrument cluster. The original MCU1 architecture used an independent computer for the instrument cluster, providing redundancy. The MCU2 retrofit consolidated both displays onto a single processor with no fallback mode. The first MCU2 replacement unit experienced a touchscreen digitizer failure — touch input stopped responding but the displays remained powered and the instrument cluster continued to function. Tesla replaced it with a second MCU2 unit. The second MCU2 unit has experienced three complete blackout events where both the center display and the instrument cluster simultaneously lose all power — no backlight, no image, no data. One of these events occurred while driving at speed on the road. I lost all instrumentation: speedometer, gear indicator, turn signal feedback, warning lamps, backup camera, and climate controls. I had to pull over with no way to confirm my speed or signal to other drivers. The vehicle remained mechanically drivable — steering, brakes, and motor continued to function. During the recent blackout a few days back, the vehicle had been stored in a closed garage and was not heat-soaked. I have video evidence of the car with both screens completely dead while the vehicle is in gear and moving. A scroll-wheel reboot restored the screens each time. This is my fourth service visit to Tesla for this upgrade. The MCU2 architecture provides no independent fallback display for critical safety information such as speed, gear state, or warning indicators during a processor crash. The prior MCU1 system maintained instrument cluster functionality independently of the infotainment computer.

My Tesla wouldn’t charge at Level 3, 2, or 1 charger resulting in the need for the tow and further service hours. Following the service I was told it was a software issue and that a power cycle resolved the issue which locked out the charging. It’s deeply concerning and baffling that this could happen at anytime resulting in days or weeks or down time for what is ultimately a software issue. This is my fourth hardware related software issue following a Tesla update.

This happens about 30%to 40% of the time when using Full Self Driving Supervised on HW3, FSD version 12.6.4, software version 2026.14.6. When changing marked lanes to the right, either initiated by FSD or the driver asking FSD to move to the right by engaging the right turn signals, it will do one of 2 things: 1. Change lanes properly about 70% of the time 2. Start and abort the lane. Hange swerving back and forth between the 2 lanes, ot 3. Does nothing and drives straight without changing lanes, all the while with the turn signals on. #2 is particularly dangerous.

Using FSD. Stopped at a stop sign making a UPL into a 4-lane 35 MPH posted street. TWICE now there was a small opening which would require an aggressive accelerator - it started the turn stopping a full car length into the first lane and decides it's going to wait for closing traffic from the right. Obviously stopping in the middle of new oncoming traffic from the left is not very wise. This has happened 3 times with 2026.8.3 and I've never seen it before - twice i gunned it to force the short turn but missed it once. Definitely a pucker maneuver.

Here’s a clear, professional paragraph you can use for your NHTSA report: ⸻ While using Tesla’s Auto Summon feature in a controlled parking environment, my vehicle (2017 Tesla Model S) made unintended contact with a stationary garage pillar. At the time, I was actively supervising the vehicle as required, and it was operating at low speed. The vehicle appeared to misjudge clearance while maneuvering, resulting in a sideswipe to the front passenger side and damage to the side mirror. This incident posed a safety risk as the vehicle’s automated steering did not maintain adequate distance from a fixed object, which could present greater danger in tighter environments or near pedestrians. There were no warning lamps, alerts, or abnormal sounds prior to the incident to indicate an imminent issue. No emergency crews responded, and there were no injuries. The collision involved only a stationary object (garage pillar).

The charge port latch failed to release the mobile connector (consistent with TSB SB-18-44-002) I had to call Tesla customer service for manual release instructions, which was very difficult to get through to (unclear through the Tesla App) After manual release, the mobile connector was damaged since it got stuck during a rainstorm. Tesla replaced the entire charging port for ~$1,000 without first testing the mobile connector Though a known defect, TSB SB-18-44-002 was never applied to my vehicle and since my vehicle was out of warranty, I was charge for the full replacement of the charging port. I was put at risk because I was stranded with a charging port cable unable to release from my vehicle and unable to drive.

I am reporting a serious safety defect regarding the front control arms on my 2017 Tesla Model S (VIN: [XXX] ). The front control arm bushings are failing, with visible cracking and tearing, as documented by a certified mechanic. These failures directly compromise vehicle steering, handling, and safety, creating a high risk of loss of control or accident. Tesla has issued a known service bulletin related to this issue, yet refused to perform repairs free of charge, despite acknowledging the bulletin exists. Timeline of Communications and Attempts to Resolve: Dec 2015 – First reported issue to Tesla Service Center. Inspection was refused without a payment of $270. Tesla claimed the vehicle was out of warranty and refused free inspection or repair. Independent Mechanic Inspection – Confirmed front control arm bushings are cracked/ripped; photos were taken. Dec 27, 2025 – Email sent to [XXX] . Received a call from a local Tesla center stating nothing could be done because the car was out of warranty. I explained it is a safety issue, but it was disregarded. Jan 10 and Jan 18, 2026 – Follow-up emails sent to [XXX] , but no response was received. Jan 23, 2026 – Email sent to [XXX] , documenting safety concerns and service bulletin reference; no acknowledgment or response was received. I and Tesla have all the emails amd photos but unfortunately I was nit able to attach. If requested I can email or fi d out ways to shareholders. Please let me know.

I pulled into a parking lot, and noticed that my passenger side rear wheel was leaning into the car. Luckily I was next to a Firestone and the mechanic told me the rear control arm broke off. Had I have been driving even for 2 more minutes, the wheel would have came off completely. When I pulled in, there was no noise, vibration, or any other indication that something was wrong. I know for a fact I didnt hit any curbs or large potholes. It was a normal drive.

CRITICAL SAFETY FAILURE: Loss of Driver Override and Extreme HMI/Signaling Latency. 1. Loss of Override & Unintended Acceleration: While operating FSD (Supervised), the vehicle ignored a 65 mph set-point and accelerated to 80 mph. I attempted to reduce speed by pulling down on the steering stalk 4-5 times, but the vehicle ignored all manual inputs, requiring a hard disengagement. 2. Lane Departure / Path Failure: The vehicle failed to maintain lane centering, specifically crossing over the centerline into opposing traffic. This occured without warning or system-initiated steering alerts 3. False Signaling / Path Failure: I’ve seen at least two occurrences where system exhibits dangerous signaling conflicts, such as activating a right-turn signal while simultaneously executing a left-turn maneuver. One time it was on a 45–55 mph rural corridor where trailing drivers frequently overtake slower vehicles. A false right-turn signal acts as a dangerous "all-clear" for a trailing driver to pass on the left, creating a high- probability broadside collision scenario when the Tesla physically executes its left turn. I have no idea if this has occurred more than these two times as I don’t check this. The other time I caught on video, by chance, as I was trying to capture the surging behavior to show the Tesla service center 4. Audio & Visual HMI Latency: Audible instructions arrive 100+ feet after turns, and the map UI auto-zooms away from the driver’s focus, requiring constant manual screen contact to view street names. This forces significant Visual-Manual Distraction. 5. Confirmed Inadequacy: Tesla Service Invoice #[XXX] (Jan 27, 2025) documents: 'The current computer is a little too slow for full self driving function...' confirming the hardware is unfit for safety-critical processing. This incident is directly relevant to NHTSA Investigation PE25012. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The contact owned a 2017 Tesla Model S. The contact stated that while starting the vehicle, an Autopilot disabled warning message system was displayed a day prior. The contact reached out to the Tesla hotline for assistance regarding the failure. The contact was advised to continue driving the vehicle, and the system error message was expected to clear. The contact stated that after multiple drives, the warning message did not disappear. The contact stated that while coming to a stop, the brake system became inoperable. The contact stated that the vehicle then accelerated to approximately 35 MPH, causing the contact to rear-end another vehicle. Multiple warning messages were displayed, including: traction and stability control disabled, automatic emergency braking system fault, battery management system critical fault, and electrical system reduced, as reported through Tesla chat assistance. The contact also stated that all air bags deployed. No injuries were sustained, and no medical attention was provided. A police report was filed. The vehicle was towed and deemed a total loss. The dealer was contacted; however, the vehicle was not diagnosed or repaired. The manufacturer was not made aware of the failure. The approximate failure mileage was 98,787.

This is a supplemental filing to my prior NHTSA complaint (#11697718) regarding a high-voltage isolation fault and shutdown risk. The vehicle displayed warnings including “vehicle may shut down during driving,” “may not charge,” and repeated BMS isolation fault messages. It became inoperable at a public charging station. The manufacturer confirmed isolation faults in the drive unit and the A/C compressor. Their own service notes stated that the vehicle “may shut down during regular driving” and that charging “may not be safe.” Despite this, the vehicle was left at 0% state of charge for an extended period and then charged by the manufacturer. They later stated to a regulator that the vehicle was “trickle charged at 1 amp for 6 hours,” but the vehicle’s range increased by approximately 100 miles, which is not physically possible at that charging current (1 amp at 240V for 6 hours = 1.44 kWh ≈ 4–5 miles). This discrepancy suggests the vehicle may have been charged at a higher rate than claimed and without proper cooling, despite the documented A/C failure that is necessary for battery thermal management. Battery condition is unknown because the manufacturer refused to perform or provide a battery health analysis, isolation resistance values, thermal logs, or charging session data. The safety defect could not be verified as repaired. While this safety issue remained unresolved, the manufacturer rejected a Tesla roadside tow arranged under regulator instruction to second service center and instead arranged an unauthorized tow to remove the vehicle from their facility without my consent. The vehicle was taken to a non-manufacturer storage lot while still in an unsafe state. I am concerned about: • high-voltage isolation faults, • shutdown risk during driving, • unsafe charging performed by the manufacturer, • possible battery damage from low SOC and charging without A/C cooling, and • mishandling of an active safety defect. The vehicle is available for inspection.

A certified independent EV repair facility (The Electrified Garage) inspected the vehicle on 11/17/2025 and documented the following safety defects: • failing/worn suspension components (control arms, thrust arms, cracked bushings) • torn sway-bar link boots • inoperative right-rear window regulator • driver window contacting internal wiring harness • moisture in the rear inner tail lamp • previous A/C drain blockage causing interior water intrusion These issues pose risks related to steering stability, electrical safety, visibility, and structural integrity. All of these conditions existed prior to the sale and were not disclosed. I am requesting NHTSA to log this complaint for federal safety review as these defects involve suspension, electrical moisture intrusion, and visibility issues that may impact the safe operation of the vehicle.

Upon purchasing the vehicle, I discovered multiple critical safety defects that were not disclosed at the time of sale and were confirmed by an independent EV specialist (Electrified Garage). These defects include worn and failing front and rear suspension components (control arms, thrust arms, and cracked/damaged bushings), a failing sway bar link boot, and a malfunctioning window that makes contact with the internal wiring harness. The suspension defects create instability over bumps and uneven roads, producing clunks, shifting, and vibration that affect steering control and overall stability. These issues present a risk of suspension failure while driving, which could cause loss of control. The window/wiring contact also poses a potential electrical hazard if the harness becomes damaged. The independent inspection documented that these defects existed before I took possession of the vehicle. The dealer did not disclose any of these issues, and the defects were not visible during a standard test drive. I am reporting this because the suspension defects directly affect vehicle handling, safety, and crash-avoidance capability. I want NHTSA to be aware in case similar defects appear in other vehicles of the same model/year.

This is an update to NHTSA Complaint #XXX with new safety information. My 2017 Tesla Model S (VIN [XXX] ) has a confirmed high-voltage isolation fault. Tesla replaced the rear drive unit under warranty, but Tesla’s own technician notes now state: “There is a risk of isolation alerts reoccurring during regular driving, use of HVAC system, or DC charging.” “Vehicle may power off due to isolation faults when the air conditioning is used.” This is Tesla acknowledging in writing that the vehicle may shut off during normal driving, even after repair. This presents a serious crash risk. The original failure occurred during Supercharging, with warnings including: • “Electrical system power reduced — vehicle may shut down unexpectedly” • “Vehicle may not restart” • “Air conditioning reduced — DC charging reduced” Tesla reproduced the isolation fault during diagnosis. Even after replacing the rear drive unit, Tesla documented that the isolation defect still exists and prevents a battery health check or DC fast-charge validation. Tesla has attempted to return the vehicle to me in this unsafe condition, while admitting the defect persists. They also stated they may charge storage fees or tow the vehicle, despite the unresolved safety issue. The defect affects the HV bus and can cause loss of propulsion, shutdown during driving, and charging failure. Tesla has not provided numeric test results (megohm isolation readings, insulation tests, or validation data) proving the vehicle is safe. This is an ongoing, manufacturer-confirmed HV isolation defect that can lead to sudden power loss. I request NHTSA review Tesla’s handling of this issue and link this filing to Case #XXX.

While charging at a Tesla Supercharger, the vehicle began making extremely loud mechanical noises on October 7, 2025, as if something inside the high-voltage system was about to explode. A warning appeared stating “Vehicle may shut down at any time.” A service request was opened the next day. Tesla scheduled the first available appointment nearly a month later, leaving the vehicle unsafe to drive. Before that appointment date, on October 31, 2025, the vehicle completely shut down at a Supercharger and could not be restarted. Tesla Roadside Assistance was dispatched three times before the car was successfully towed to a Tesla Service Center. The failure was diagnosed by the service center as a high-voltage isolation fault logged in the Battery Management System. The problem disables the vehicle suddenly and without warning, posing a serious safety hazard if it occurs while driving. Warning lamps and shutdown messages were present prior to the failure. Tesla service staff stated they could not access diagnostic data until the customer paid for unrelated parts (12-volt battery and A/C compressor). After being challenged, they later retrieved limited battery data proving that the high-voltage system had recorded faults. Tesla has not yet issued a written warranty determination or performed a full battery inspection. The incident demonstrates that a high-voltage battery isolation fault can cause the vehicle to become completely inoperable and may create risk of sudden loss of power while driving or charging. The component (battery pack and related electrical systems) remains in Tesla’s possession and can be inspected upon request.

The Office of Defects Investigation (ODI) is opening this Engineering Analysis to evaluate Tesla’s Full Self Driving Beta and Full Self Driving (Supervised) (collectively, FSD) degradation detection system. The focus of this investigation will be to assess the system’s ability, when encountering reduced roadway visibility conditions, to detect degradation and alert the driver with sufficient time to respond. ODI will evaluate the performance of FSD in degraded roadway conditions and the updates or modifications by Tesla to the degradation detection system, including the timing, purpose, and capabilities of the updates, and Tesla’s assessment of their safety impact. Tesla’s FSD is an advanced driver assistance system (ADAS) that relies exclusively on vision-based cameras and the related FSD software to detect and respond to the roadway ahead, projecting a path forward based on traffic control devices, vehicles, pedestrians, and the roadway itself. When Tesla began transitioning away from using both cameras and radars to an exclusively camera-based approach, known as Tesla Vision, in mid-2021, it developed and implemented a degradation detection system that it deployed by a software update to existing and new Tesla vehicles. On June 28, 2024, the day after Tesla submitted the SGO report of the November 28, 2023 fatal crash listed in this document, Tesla began developing an update to the degradation detection system. At this time, ODI does not have information on when the update was deployed and which vehicles have the updated system. ODI discussed individual incidents and its initial findings during the PE phase of its investigation with Tesla. As part of those discussions, Tesla’s post-incident analysis indicated that the update to the degradation detection system, had it been installed on the vehicles at the time, may have affected 3 of the 9 incidents identified by ODI. Tesla also described internal data and labeling limitations that prevented a uniform identification and analysis of crash events with the subject system engaged. ODI believes this limitation could have led to under-reporting of subject crashes over portions of the defined time-period. Available incident data raise concerns that Tesla’s degradation detection system, both as originally deployed and later updated, fails to detect and/or warn the driver appropriately under degraded visibility conditions such as glare and airborne obscurants. In the crashes that ODI has reviewed, the system did not detect common roadway conditions that impaired camera visibility and/or provide alerts when camera performance had deteriorated until immediately before the crash occurred. Review of Tesla’s responses revealed additional crashes that occurred in similar environments and where the system either did not detect a degraded state, and/or it did not present the driver with an alert with adequate time for the driver to react. In each of these crashes, FSD also lost track of or never detected a lead vehicle in its path. In upgrading PE24031 to an Engineering Analysis (EA), ODI will gather further information on the updated degradation detection system, including the status of updating vehicles and scope of compatible vehicles, the system’s visibility degradation detection capability, and alerts or warnings to the driver. Lastly, ODI will conduct analysis on six recent potentially related incidents. These incidents can be found at NHTSA.gov under the following SGO report identification numbers: 13781-11937, 13781-13211, 13781-13569, 13781-13633, 13781-13693, 13781-13788. The crashes included in the failure report summary can be found at NHTSA.gov under the following SGO report identification numbers: 13781-8004, 13781-7181, 13781-7381, 13781-7767, 13781-7964, 13781-8977, 13781-9267.
- Traffic safety violations while Full Self Driving ("FSD") is engaged

The Office of Defects Investigation (“ODI”) is opening this Preliminary Evaluation (PE) to assess the scope, frequency, and potential safety consequences of FSD executing driving maneuvers that constitute traffic safety violations. This investigation concerns versions of FSD that Tesla has labeled as "FSD (Supervised)" and "FSD (Beta)." Tesla characterizes FSD as an SAE Level 2 partial automation system requiring a fully attentive driver who is engaged in the driving task at all times. Level 2 partial automation systems are designed to support and assist the driver in performing certain aspects of the driving task, requiring a driver to supervise and intervene as necessary. The driver remains fully responsible at all times for driving the vehicle, including complying with applicable traffic laws. ODI’s investigation will therefore focus, in particular, on whether certain driving inputs within the control authority of FSD forestall the driver’s supervision when they are unexpectedly performed. ODI has identified a number of incidents in which the inputs to the dynamic driving task commanded by FSD induced vehicle behavior that violated traffic safety laws. Although reports of this nature span a variety of behaviors, the reports appear to most commonly involve two types of scenarios. The first type of scenario involves a vehicle operating with FSD proceeding into an intersection in violation of a red traffic signal. The second type of scenario involves FSD commanding a lane change into an opposing lane of traffic. With respect to the first type of scenario, ODI has identified 18 complaints and 1 media report alleging that a Tesla vehicle, operating at an intersection with FSD engaged, failed to remain stopped for the duration of a red traffic signal, failed to stop fully, or failed to accurately detect and display the correct traffic signal state in the vehicle interface. Some complainants also alleged that FSD did not provide warnings of the system's intended behavior as the vehicle was approaching a red traffic signal. ODI has identified six Standing General Order ("SGO") reports in which a Tesla vehicle, operating with FSD engaged, approached an intersection with a red traffic signal, continued to travel into the intersection against the red light and was subsequently involved in a crash with other motor vehicles in the intersection. Of these incidents, four crashes resulted in one or more reported injuries. At least some of the incidents appeared to involve FSD proceeding into the intersection after coming to a complete stop. ODI's pre-investigative work, including coordination with the Maryland Transportation Authority and State Police, indicated that the problem may be repeatable, given that multiple subject incidents occurred at the same intersection in Joppa, Maryland. NHTSA understands that Tesla has since taken action to address the issue at this intersection. With respect to the second type of scenario, ODI has identified 2 SGO reports, 18 complaints, and 2 media reports alleging that a Tesla vehicle, operating with FSD engaged, entered opposing lanes of travel during or following a turn, crossed double-yellow lane markings while proceeding straight, or attempted to turn onto a road in the wrong direction despite the presence of wrong-way road signs. Likewise, ODI has identified 4 SGO reports, 6 complaints, and 1 media report alleging that a Tesla vehicle, operating with FSD engaged, proceeded straight through an intersection in a turn-only lane or executed a turn at an intersection in a through lane despite the presence of lane markings or signals. Complaints also alleged that FSD did not provide warnings of the system's intended behavior. Some complaints alleged that more than one of these failures occurred and, as such, the numbers are not cumulative. Some of the reported incidents appeared to involve FSD executing a lane change into an opposing lane of travel with little notice to a driver or opportunity to intervene. ODI’s review will assess whether there was prior warning or adequate time for the driver to respond to the unexpected behavior or to safely supervise the automated driving task. This review will assess any warnings to the driver about the system's impending behavior; the time given to drivers to respond; the capability of FSD to detect, display to the driver, and respond appropriately to traffic signals; and the capability of FSD to detect and respond to lane markings and wrong-way signage. NHTSA's review will also consider any updates or modifications to the system(s) that may affect the performance of FSD with respect to obeying traffic safety laws and signals. This assessment will focus, in particular, on the types of traffic safety violations described above, as most reports identified thus far have centered around those behaviors. While the behaviors under investigation appear to occur most frequently at intersections, NHTSA’s investigation will encompass any other types of situations in which this behavior may arise, such as when traveling adjacent to a lane of opposing traffic or when approaching railroad crossings. If other evidence received during this investigation involve other types of traffic safety violations, those may be considered as part of this assessment as well.

The Office of Defects Investigation (“ODI”) has identified numerous incident reports submitted by Tesla, Inc. (“Tesla”) in response to Standing General Order 2021-01 (the “SGO”), in which the reported crashes occurred several months or more before the dates of the reports. The majority of these reports involved crashes in which the Standing General Order in place at the time required a report to be submitted within one or five days of Tesla receiving notice of the crash. When the reports were submitted, Tesla submitted them in one of two ways. Many of the reports were submitted as part of a single batch, while others were submitted on a rolling basis. Preliminary engagement between ODI and Tesla on the issue indicates that the timing of the reports was due to an issue with Tesla’s data collection, which, according to Tesla, has now been fixed. NHTSA is opening this Audit Query, a standard process for reviewing compliance with legal requirements, to evaluate the cause of the potential delays in reporting, the scope of any such delays, and the mitigations that Tesla has developed to address them. As part of this review, NHTSA will assess whether any reports of prior incidents remain outstanding and whether the reports that were submitted include all of the required and available data. The SGO reports cited in the Opening Resume, can be found at NHTSA.gov/SGOCrashReporting under the following SGO 2021-01 report IDs: 13781-11020-1 13781-10844-1 13781-10843-1 13781-10530-1 13781-10160-1 13781-10159-1 13781-10157-1 13781-10146-1 13781-10122-1 13781-10098-1 13781-10097-1 13781-10096-1 13781-10095-1 13781-10094-1 13781-10093-1 13781-10023-1 13781-10022-1 13781-10021-1 13781-10020-1 13781-10017-1 13781-10016-1 13781-10015-1 13781-10014-1 13781-10013-1 13781-10012-1 13781-6047-1 13781-9930-1 13781-9917-1 13781-9928-1 13781-9925-1 13781-9924-1 13781-9923-1 13781-9922-1 13781-9835-1 13781-9834-1 13781-9833-1 13781-9832-1 13781-9831-1 13781-9830-1 13781-9829-1 13781-9827-1 13781-9818-1 13781-9780-1 13781-9779-1 13781-9778-1 13781-9777-1 13781-9775-1 13781-9774-1 13781-9773-1 13781-9772-1 13781-9771-1 13781-9770-1 13781-9728-1 13781-9688-1 13781-9715-1 13781-9714-1 13781-9713-1 13781-9712-1 13781-9711-1 13781-9710-1 13781-9709-1 13781-9696-1 13781-9695-1 13781-9694-1 13781-9693-1 13781-9692-1 13781-9691-1 13781-9690-1 13781-9687-1 13781-9686-1 13781-9342-1 13781-9319-1 13781-9019-1 13781-8910-1 13781-8732-1 13781-8712-1 13781-8310-1 13781-7897-1 13781-7895-1 13781-7835-1 13781-7798-1 13781-7797-1 13781-7758-1 13781-7757-1 13781-7756-1 13781-7755-1 13781-7667-1 13781-7399-1 13781-7398-1 13781-7397-1 13781-7396-1 13781-7395-1 13781-7394-1 13781-7393-1 13781-7389-1 13781-7388-1 13781-7387-1 13781-7386-1 13781-7385-1 13781-7383-1 13781-7187-1 13781-7186-1 13781-7185-1 13781-7184-1 13781-7181-1 13781-7023-1 13781-6399-1 13781-6389-1 13781-6388-1 13781-6387-1 13781-6386-1 13781-6379-1 13781-6378-1 13781-6377-1 13781-6375-1 13781-6214-1 13781-6172-1 13781-6155-1 13781-6154-1 13781-6122-1 13781-6120-1 13781-6118-1 13781-5800-1
- Actually Smart Summon sessions resulting in low-speed impacts.
On January 6, 2025, the Office of Defects Investigations (ODI) opened Preliminary Evaluation 24003 (PE24033) to investigate Actually Smart Summon (Summon) sessions resulting in crashes during active sessions.

On January 6, 2025, the Office of Defects Investigations (ODI) opened Preliminary Evaluation 24003 (PE24033) to investigate Actually Smart Summon (Summon) sessions resulting in crashes during active sessions. According to Tesla, Summon is a short-distance SAE Level 2 system, controlled by the user from a cell phone within a certain distance and intended for use in parking lots and on private property. ODI analyzed complaint data provided by Tesla as well as complaints submitted to ODI from consumers to identify Summon incidents resulting in crashes. ODI's analysis indicates that almost all Summon reported crashes involved minor property damage claims with no reported incidents involving a vulnerable road user, injury, fatality, or major property damage as indicated by an air bag deployment or vehicle tow away. Out of millions of Summon sessions, a fraction of 1% resulted in an incident. Almost all those incidents took place where, typically early in a Summon session, the system or person using the app failed to fully detect or respond appropriately to vehicle surroundings resulting in minor impacts. Incidents took place when app users did not have a complete 360-degree view of the surroundings in the app to assess situational awareness. This limited the app user’s ability to determine whether an impact was imminent during initial vehicle maneuvers such as reversing in close proximity to an obstacle or a curb. ODI found that the impacts most often occurred with parking gates, adjacently parked vehicles, and short parking bollards. During this investigation, ODI identified two Summon crashes related to camera blockages. In both crashes, Summon attempted to navigate a snowy parking lot with snow partially or fully obstructing the forward-facing cameras. Summon did not detect the camera blockage and the vehicles collided with unoccupied parked vehicles while navigating the parking lot. App users in both instances did not command a vehicle stop or pause despite the obstructed camera visible in the camera stream in the app. On January 15, 2025, Tesla released Over-the-Air (OTA) Software (SW) Update Action numbers 578998 and 579185 for vehicles in service to implement a camera blockage detection condition. Both OTAs improve camera blockage detection mechanisms. Additionally, on January 20, 2025, and January 30, 2025, Tesla identified additional system requirements associated with camera visibility checks and released OTA SW-578752 and SW-580322, respectively. These firmware updates reduce false negative camera blockage detections due to snow or condensation. In its investigation, ODI identified one Summon incident where the vehicle did not yield for a gate arm blocking a garage exit lane and the app user did not command a vehicle stop or pause, resulting in an impact. On February 6, 2025, Tesla deployed OTA SW-578839 to improve vehicle reaction to dynamic gates. This OTA update upgraded vehicle perception systems through a high-fidelity occupancy determination network, which uses data from vehicle sensory systems to improve reconstruction of field objects with high accuracy. On November 20, 2025, Tesla further improved vehicle performance by adding object detections from a separate neural network through OTA SW-580514. Owners of the affected vehicles received all six OTA SW updates. Tesla also released these SW updates to production vehicles. See online public file for detailed descriptions of all six OTA SW updates. Due to low incident occurrence and low incident severity, this preliminary evaluation is closed. The closing of this investigation does not constitute a finding that a safety-related defect does not exist. The agency reserves the right to take additional action if warranted by future circumstances. For additional information regarding this investigation, see the complete online public file.
- FSD Collisions in Reduced Roadway Visibility Conditions
On October 17, 2024, NHTSA’s Office of Defects Investigation (ODI) opened a Preliminary Evaluation (PE24031) of Tesla’s Full Self Driving Beta and Full Self Driving (Supervised) (collectively, FSD) to assess: the ability of the FSD system to detect and respond appropriately to reduced roadway visibility conditions…
On October 17, 2024, NHTSA’s Office of Defects Investigation (ODI) opened a Preliminary Evaluation (PE24031) of Tesla’s Full Self Driving Beta and Full Self Driving (Supervised) (collectively, FSD) to assess: the ability of the FSD system to detect and respond appropriately to reduced roadway visibility conditions; whether any other FSD crashes had occurred under degraded roadway visibility conditions that are similar in nature to the four SGO-reported crashes identified in the opening document, and if so, the contributing circumstances for each of those crashes; and any updates or modifications by Tesla to the FSD system that may affect the performance of FSD in degraded roadway visibility conditions, including the timing, purpose, and capabilities of any such updates, and Tesla’s assessment of their safety impact. Tesla’s FSD is an advanced driver assistance system (ADAS) that relies exclusively on vision-based cameras and the related FSD software to detect and respond to the roadway ahead, projecting a path forward based on traffic control devices, vehicles, pedestrians, and the roadway itself. During this phase of the investigation, ODI reviewed the materials provided by Tesla detailing any actions taken, or changes, modifications, and updates made that may relate to the alleged defect. ODI reviewed information related to Tesla’s transition to a vision-only perception system, and its deployment of the strategy in vehicles. ODI’s findings include information on limitations of the vision-only perception system and updates made in response to known subject crashes. When Tesla began transitioning away from using both cameras and radars to an exclusively camera-based approach, known as Tesla Vision, in mid-2021, it developed and implemented a degradation detection system that it deployed by a software update to existing and new Tesla vehicles. On June 28, 2024, the day after Tesla submitted the SGO report of the November 28, 2023 fatal crash listed in this document, Tesla began developing an update to the degradation detection system. ODI reviewed certain public statements, including those made during an April 2025 earnings call, in which Tesla stated that it had developed a breakthrough “direct photon-counting” capability that eliminates the degradation that the camera-based system experiences when glare is encountered. At this time, ODI does not have information on when the update was deployed and which vehicles have the updated system. ODI has discussed individual incidents and its initial findings with Tesla. Based on Tesla’s post-incident analysis, the update to the degradation detection system, had it been installed on the vehicles at the time, may have affected 3 of the 9 incidents identified by ODI. Review of Tesla’s responses revealed additional crashes that occurred in similar environments and where the system either did not detect a degraded state, and/or it did not present the driver with an alert with adequate time for the driver to react. In each of these crashes, FSD also lost track of or never detected a lead vehicle in its path. Tesla also described internal data and labeling limitations that prevented a uniform identification and analysis of crash events with the subject system engaged. ODI believes this limitation could have led to under-reporting of subject crashes over portions of the defined time-period. Available incident data raise concerns that Tesla’s FSD system fails to detect and/or warn the driver appropriately under degraded visibility conditions such as glare and airborne obscurants where the camera-based system performance degrades significantly. In the crashes that ODI has reviewed, the FSD system did not detect common roadway conditions that impaired its visibility and/or provide alerts when camera performance had deteriorated until immediately before the crash occurred. ODI is upgrading this investigation (PE24031) to Engineering Analysis (EA) 26002 to further evaluate this matter. The crashes included in the failure report summary can be found at NHTSA.gov under the following SGO report identification numbers: 13781-8004, 13781-7181, 13781-7381, 13781-7767, 13781-7964, 13781-8977, 13781-9267.
- Recall 23V838 Remedy Effectiveness
The Office of Defects Investigation (ODI) is opening a Recall Query to assess the remedy adequacy of Recall 23V838.

The Office of Defects Investigation (ODI) is opening a Recall Query to assess the remedy adequacy of Recall 23V838. On December 12, 2023, Tesla filed a Defect Information Report (Recall 23V838) applicable to all Tesla models produced and equipped with any version of its Autopilot system, which Tesla described as an SAE Level 2 (L2) Advanced Driver Assistance System (ADAS). Autopilot is the simultaneous engagement of Tesla’s Traffic-Aware Cruise Control (TACC) and Autosteer. In describing the safety defect, Tesla’s Defect Information Report (DIR) explained that “the prominence and scope of the system’s controls may be insufficient to prevent driver misuse,” and Tesla committed to the deployment of a multipart remedy aimed at improving system and engagement controls and reducing mode confusion. EA22002 (upgraded from PE21020) was opened to investigate whether Tesla’s Autopilot contained a defect that created an unreasonable risk to motor vehicle safety and involved extensive crash analysis, human factors analysis, vehicle evaluations, and assessment of vehicle control authority and driver engagement technologies. The work conducted in these investigations aligns with Tesla’s conclusion in its 23V838 recall filing. During EA22002, ODI identified at least 13 crashes involving one or more fatalities and many more involving serious injuries in which foreseeable driver misuse of the system played an apparent role. Tesla filed Recall 23V838 to address concerns regarding the Autopilot system investigated in EA22002. Following deployment of the remedy in Recall 23V838, ODI identified concerns due to post-remedy crash events and results from preliminary NHTSA tests of remedied vehicles. Also, Tesla has stated that a portion of the remedy both requires the owner to opt in and allows a driver to readily reverse it. Tesla has also deployed non-remedy updates to address issues that appear related to ODI’s concerns under EA22002. This investigation will consider why these updates were not a part of the recall or otherwise determined to remedy a defect that poses an unreasonable safety risk. ODI is therefore opening this Recall Query investigation to further evaluate the adequacy of the remedy for recall 23V838.

The Office of Defects Investigation (ODI) received a petition requesting that ODI reevaluate its decision to deny DP20-001 on the basis that intermittent high electrical current demands on the vehicles' 12VDC systems may have caused some or all of the incidents examined by ODI in DP20-001. The petitioner bases this information on a review of open-source research and the DP20-001 denial. The petition and related materials can be reviewed at NHTSA.gov under the following ODI number: 11528471.
- Defect Petition Interlock Request
On March 21, 2023, the Office of Defects Investigation (ODI) received a petition requesting a “recall of all Tesla cars” produced from 2013 to the date on which the petition was filed due to what Petitioner considers to be the increased likelihood of pedal misapplication.

On March 21, 2023, the Office of Defects Investigation (ODI) received a petition requesting a “recall of all Tesla cars” produced from 2013 to the date on which the petition was filed due to what Petitioner considers to be the increased likelihood of pedal misapplication. Attached to the Petition is a paper authored by Petitioner. According to Petitioner, the differences in the operator controls between the subject Tesla vehicles and internal combustion engine powered vehicles promote driver pedal misapplication, leading to sudden unintended acceleration (SUA) incidents. To fix this alleged defect, Petitioner argues that the subject vehicles should be equipped with measures that require: (i) occasional removal of the driver’s foot from the pedals; and (ii) application of the brake pedal before fully stopping the vehicle. ODI evaluated the allegations by, among other things, reviewing the Petition and supporting technical paper, and analyzing Tesla’s response to ODI’s Information Request. ODI is denying this Petition. ODI has not found evidence that warrants the opening of a safety defect investigation into the Tesla vehicles as described in the Petition. The use of regenerative braking controlled by the accelerator pedal, or one-pedal driving, is common across most light vehicle manufacturers of electric vehicles and Tesla vehicles are not unique in this respect. Further, ODI identified only a handful of collisions potentially within the scope of the alleged defect; and corresponding vehicle data demonstrated that the subject vehicles responded appropriately to control inputs by their drivers. Moreover, ODI is unaware of any evidence to suggest that Petitioner’s proposed interlock would have prevented alleged SUA events as apparently described in the Petition and supporting materials. Accordingly, the Agency is denying the petition. As with all potential motor vehicle safety risks, NHTSA will continue to review any new information or incidents as they are submitted to the Agency.
- Pedestrian alert sounds
NHTSA received a petition on or about July 18, 2022, requesting that Federal Motor Vehicle Safety Standard (FMVSS) 141 be applied to all electric and hybrid vehicles operating in the United States. The petition can be reviewed at NHTSA.gov under ODI Number 11486072. FMVSS 141 establishes performance requirements for…
NHTSA received a petition on or about July 18, 2022, requesting that Federal Motor Vehicle Safety Standard (FMVSS) 141 be applied to all electric and hybrid vehicles operating in the United States. The petition can be reviewed at NHTSA.gov under ODI Number 11486072. FMVSS 141 establishes performance requirements for pedestrian alert sounds for motor vehicles. The standard applies to hybrid and electric vehicles that have a gross vehicle weight rating of 4,536 KG or less or are defined as low-speed vehicles. The standard became fully applicable to all such vehicles manufactured on or after March 1, 2021.On January 27, 2023, NHTSA opened Defect Petition (DP) 22-005 to evaluate the subject matter described in the petition. On June 24, 2023 and as supplemented on June 25, 2023, the petitioner notified NHTSA he was withdrawing his petition. The petitioner indicated that, based on his review of data, there is no justification for asserting potential benefits that could be derived from actions sought by my petition. Based on the petitioner's withdrawal, DP22-005 is closed. Closure of this DP does not represent a determination by NHTSA regarding the subject matter of the petition.
- Autopilot System Driver Controls
The Office of Defects Investigation (ODI) upgraded PE21020 to EA22002 on June 8, 2022, to extend work and deepen the PE21020 crash analysis, to supplement that analysis with additional data, and to perform vehicle evaluations to understand how Tesla’s Autopilot system may exacerbate human factors or behavioral safety…
The Office of Defects Investigation (ODI) upgraded PE21020 to EA22002 on June 8, 2022, to extend work and deepen the PE21020 crash analysis, to supplement that analysis with additional data, and to perform vehicle evaluations to understand how Tesla’s Autopilot system may exacerbate human factors or behavioral safety risks by undermining the effectiveness of the driver’s supervision. To support this work, ODI collected additional crash information and assessed vehicle control authority, driver engagement technologies, and related human factors considerations associated with partial automation via analysis of peer vehicle data and hands-on vehicle evaluation, assessments from NHTSA human factors subject matter experts, and reviews of related publications dedicated to partial driving automation. Autopilot is the simultaneous use of the features that Tesla calls Traffic-Aware Cruise Control (TACC) and Autosteer. TACC is a type of adaptive cruise control that, like traditional cruise control, maintains a set speed but also slows or accelerates as necessary to maintain the vehicle’s following distance from a vehicle in front. As designed, Autosteer detects lane markings and the presence of other nearby vehicles and objects to keep the vehicle in its driving lane. Autopilot is characterized by Tesla as an SAE Level 2 (“L2 system”) partial driving automation system that provides driver assistance through steering, propulsion, and braking within a specified driving environment under direct supervision of the driver. L2 systems should be designed to support the driver’s need to monitor the system in response to the constantly changing driving environment and, if necessary, take over the dynamic driving task. To ensure sufficient driver engagement, vehicles with L2 systems should employ driver engagement systems and usage controls that are appropriate and sufficient for the L2 system design and driver expectations. ODI completed an analysis of 956 crashes reported up to August 30, 2023. In approximately half (489) of those crashes, ODI found: 1.) that there was insufficient data to make an assessment; 2.) the other vehicle was at fault; 3.) Autopilot was found to not be in use; or 4.) the crash was otherwise unrelated to EA22002. Of the remaining 467 crashes, ODI identified trends resulting in three categories: collisions in which the frontal plane of the Tesla struck another vehicle or obstacle with adequate time for an attentive driver to respond to avoid or mitigate the crash (211), roadway departures where Autosteerwas inadvertently disengaged by the driver’s inputs (111), and roadway departures in low traction conditions such as wet roadways (145). ODI observed this pattern across all Tesla models and hardware versions. Crash and human factors assessment showed that Autopilot controls did not sufficiently ensure driver attention and appropriate use. At the same time, peer analysis and vehicle evaluations established that Autopilot invited greater driver confidence via its higher control authority and ease of engagement. This mismatch of weak usage controls and high control authority was evident in these crash categories, which included indications of driver disengagement from the driving task. This mismatch was also evident in roadway departures when the system was engaged in low traction conditions outside of Tesla’s recommendations.Additional information regarding NHTSA’s crash analysis is available in the EA22002 file. ODI reviewed these findings with Tesla during several conversations in Quarter 4 of 2023. On December 12, 2023, Tesla filed a Defect Information Report (DIR) (Recall 23V838) applicable to all Tesla models produced and equipped with any version of its Autopilot system. Tesla’s DIR described the functionality of this system, stated that the prominence and scope of the system’s controls may be insufficient to prevent driver misuse, and described a remedy to improve the effectiveness of driver warnings and to reduce mode confusion. ODI completed an extensive body of work via PE21020 and EA22002, which showed evidence that Tesla’s weak driver engagement system was not appropriate for Autopilot’s permissive operating capabilities. This mismatch resulted in a critical safety gap between drivers’ expectations of the L2 system’s operating capabilities and the system’s true capabilities. This gap led to foreseeable misuse and avoidable crashes. During EA220002, ODI identified at least 13 crashes involving one or more fatalities and many more involving serious injuries, in which foreseeable driver misuse of the system played an apparent role. ODI’s analysis conducted during this investigation, which aligns with Tesla’s conclusion in its Defect Information Report, indicated that in certain circumstances, Autopilot’s system controls and warnings were insufficient for a driver assistance system that requires constant supervision by a human driver. Given Tesla’s recall (23V838) of all vehicles equipped with Autopilot for insufficient controls to prevent misuse, ODI is closing EA22002. Concurrent with that closing, ODI has opened a Recall Query (RQ24009) to assess the effectiveness of the 23V838 remedy.

- Desiccated Air Bag Inflator Rupture
From 2000 through 2017, Takata produced millions of air bag inflators using two types of phase-stabilized ammonium nitrate ("PSAN") propellant -- propellant 2004 and propellant 2004L. After prolonged exposure to high temperature cycles and humidity, inflators using propellant 2004 can degrade, causing the propellant…
From 2000 through 2017, Takata produced millions of air bag inflators using two types of phase-stabilized ammonium nitrate ("PSAN") propellant -- propellant 2004 and propellant 2004L. After prolonged exposure to high temperature cycles and humidity, inflators using propellant 2004 can degrade, causing the propellant to burn too quickly when ignited. The rapid burning can cause the inflator to rupture during deployment, potentially causing serious or even fatal injury to vehicle occupants. See 2016 Blomquist Report at www.nhtsa.gov/sites/nhtsa.gov/files/documents/expert_report-hrblomquist.pdf.Consequently, all frontal inflators using propellant 2004 that do not contain a "desiccant" (a substance that traps and holds moisture) in US vehicles are under recall. These "non-desiccated" inflators either have been or are required to be replaced.In some cases, the remedy part for these recalled inflators was, or will be, an inflator using either propellant 2004 or 2004L that does contain a desiccant. None of these "desiccated" remedy parts (which were installed in older model year vehicles) are currently under recall for a degradation concern. Certain subsets of desiccated PSAN inflators using propellant 2004 for use as original equipment, however, have been recalled for a degradation concern. All Takata inflators produced with propellant 2004L contain desiccant, and none of these desiccated inflators using propellant 2004L are under recall for a degradation concern. There have been no reported field ruptures in any non-recalled desiccated PSAN inflators.It is understood that desiccants fully saturate at some threshold, at which point any additional moisture will not be captured. This means the degradation process observed in non-desiccated inflators using propellant 2004 may also occur in non-recalled desiccated inflators using propellant 2004, assuming additional moisture enters the inflator and high temperature cycling occurs. Based on available information, desiccant saturation can occur within the first five years in the worst environments, and the time required for full saturation is affected by multiple factors. While no present safety risk has been identified, further work is needed to evaluate the future risk of non-recalled desiccated inflators using propellant 2004.Three entities -- Takata (now known as TK Global), the Independent Testing Coalition, and Exponent -- have been studying the long-term behavior of Takata desiccated PSAN inflators using propellant 2004L (as well as 2004) in the presence of moisture and temperature cycling. The research efforts, which include development of predictive modeling techniques and field sample analysis, are ongoing. To date, none of the researchers have identified field evidence showing that propellant 2004L is undergoing a degradation process that leads to aggressive deployment and potential rupture. However, the time in service of such inflators remains short compared to that of the inflators using propellant 2004. Further study is needed to assess the long-term safety of desiccated inflators using propellant 2004L.The Office of Defects Investigation is opening this investigation to examine whether a safety defect related to propellant degradation exists in non-recalled desiccated PSAN frontal inflators manufactured by Takata. This investigation will require extensive information on Takata production processes and surveys of inflators in the field. Lists of recall actions that may have used desiccated PSAN inflators as remedy parts, as well as the makes and models originally manufactured with them, is available with the downloadable version of this document (see nhtsa.gov/recalls?nhtsaId=EA21002 -- note this information is subject to change/revision as the investigation proceeds). This investigation does not supersede EA15-001, which remains open.
- Autopilot & First Responder Scenes
On August 13, 2021, NHTSA?s Office of Defects Investigation (ODI) opened a Preliminary Evaluation (PE21-020) to assess the performance of Tesla?s Autopilot system (a system characterized by Tesla as an SAE Level 2 driving automation system designed to support and assist the driver in performing the driving task)…
On August 13, 2021, NHTSA?s Office of Defects Investigation (ODI) opened a Preliminary Evaluation (PE21-020) to assess the performance of Tesla?s Autopilot system (a system characterized by Tesla as an SAE Level 2 driving automation system designed to support and assist the driver in performing the driving task) available in Tesla vehicles. The investigation opening was motivated by an accumulation of crashes in which Tesla vehicles, operating with Autopilot engaged, struck stationary in-road or roadside first responder vehicles tending to pre-existing collision scenes. Upon opening the investigation, NHTSA indicated that the PE would also evaluate additional similar circumstance crashes of Tesla vehicles operating with Autopilot engaged, as well as assess the technologies and methods used to monitor, assist, and enforce the driver?s engagement with the dynamic driving task during Autopilot operation.PE21-020 is upgraded to an Engineering Analysis (EA) to extend the existing crash analysis, evaluate additional data sets, perform vehicle evaluations, and to explore the degree to which Autopilot and associated Tesla systems may exacerbate human factors or behavioral safety risks by undermining the effectiveness of the driver?s supervision. In doing so, NHTSA plans to continue its assessment of vehicle control authority, driver engagement technologies, and related human factors considerations.The attached Detailed Summary further describes NHTSA?s review to date and the basis for upgrade to an EA.
- Fore Link Failure
The Office of Defects Investigation (ODI) opened this Preliminary Evaluation based on forty-three complaints alleging failure of the left or right front suspension fore links in Tesla model year (MY) 2015 through 2017 Model S and MY 2016 through 2017 Model X vehicles. The investigation has identified 426 instances of…
The Office of Defects Investigation (ODI) opened this Preliminary Evaluation based on forty-three complaints alleging failure of the left or right front suspension fore links in Tesla model year (MY) 2015 through 2017 Model S and MY 2016 through 2017 Model X vehicles. The investigation has identified 426 instances of failure on part number 1041570-00-A or 1041575-00-A fore links.None of the instances resulted in any loss of vehicle control. One minor crash with no injuries is associated with the 426 instances fore link failures.A majority of the failures occurred between one to fifteen mph while parking in driveways or parking lots.In the eight instances where the vehicle was traveling more than 40 mph and the fore link failed, the vehicle remained controllable with no associated crash or injuries as a result. Tesla issued a consumer satisfaction bulletin (SB-17-31-001) on 10 February 2017, to replace the subject component on a sub-population of vehicles originally equipped with the subject fore links and built between 19 January 2016 and 25 May 2016.This sub population does not cover 75% instances of failures identified in this investigation. Additional damage to other vehicle components will occur if the vehicle is driven with this failed fore link.However no instance has shown that a failure of the fore link in this manner prevented the controllability of the vehicle in testing and reported failures. Based on this analysis,ODI is closing the investigation. ODI recommends that Tesla expand the terms of Bulletin SB-17-31-001 to cover all vehicles equipped with 1041570-00-A or 1041575-00-A fore links. This does not constitute a finding by the Agency that a safety-related defect is not present; the Agency will take further action if warranted by additional information received.

- Loss of rearview camera
On November 20, 2020, the Office of Defects Investigation (ODI) opened Engineering Analysis (EA) 20-003 to investigate incidents of media control unit (MCU) failures resulting in loss of rearview camera in model year (MY) 2012-18 Tesla Model S and model year (MY) 2016-2018 Tesla Model X vehicles equipped with the…
On November 20, 2020, the Office of Defects Investigation (ODI) opened Engineering Analysis (EA) 20-003 to investigate incidents of media control unit (MCU) failures resulting in loss of rearview camera in model year (MY) 2012-18 Tesla Model S and model year (MY) 2016-2018 Tesla Model X vehicles equipped with the NVIDIA Tegra 3 processor with an integrated 8GB eMMC NAND flash memory device. During its investigation, ODI learned that the expected usage life rating for the 8GB eMMC NAND flash memory device is approximately 3,000 “P/E” or Program-Erase cycles, after which the eMMC NAND flash memory device would become fully consumed and no longer be operational, leading to a failure of the media control unit (MCU). At a daily cycle usage rate of 1.4 per block, accumulation of 3,000 P/E cycles would take only 5-6 years. Historically, the expected life of a vehicle generally far exceeds 5-6 years of service. ODI believes that a 5- or 6-year life expectancy for a component integral to providing the driver with safety functions is insufficient. During our review of the data, Tesla provided confirmation that all units will inevitably fail given the memory device’s finite storage capacity. Tesla provided its own statistical model showing the number of projected weekly MCU repairs from 2020 to 2028, estimating that replacement rates for MCU failures will peak in early 2022 and gradually decline until (near) full part turnover has been accomplished in 2028. According to Tesla, for subject vehicles equipped with the NVIDIA Tegra 3 processor with an integrated 8GB eMMC NAND flash memory device, the eMMC NAND cell hardware will fail when reaching lifetime wear, for which the eMMC controller has no available memory blocks necessary to recover. With this failure mode, the only recovery available is a replacement of the eMMC device, achieved by physical part replacement of either the MCU assembly or visual control module subcomponent. Tesla provided information concerning the effects of MCU failure on vehicle function, which include in loss of rearview/backup camera and loss of HVAC (defogging and defrosting) setting controls (if the HVAC status was OFF status prior to failure). The failure also affects the Autopilot advanced driver assistance system (ADAS) and turn signal functionality due to the possible loss of audible chimes, driver sensing, and alerts associated with these vehicle functions. Based on this analysis, ODI issued a Recall Request Letter (RRL) on January 13, 2021. The RRL was based on ODI’s tentative conclusion that a defect related to motor vehicle safety exists in the subject vehicles because the eMMC NAND flash devices have a finite lifespan based upon the number of program/erase (P/E) cycles, after which the MCU fails due to memory wear-out, which constitutes a premature failure of safety-critical part. Tesla responded to the Recall Request Letter (RRL) on January 27, 2021, and disputed the tentative findings of the RRL. Nevertheless, on January 29, 2021, Tesla filed a safety recall (21V-035), recalling (MY) 2012-2018 Tesla Model S and (MY) 2016-2018 Model X vehicles with a center display equipped with a NVIDIA Tegra 3 processor and an 8GB eMMC NAND flash memory device. In this recall, Tesla is providing a free hardware remedy in addition to the over-the-air (“OTA”) firmware updates that the company had previously implemented. NHTSA will continue to monitor the issue as part of its ordinary processes for overseeing the effectiveness of recalls. However, based on available information, at this time, Tesla’s recall appears to address the unreasonable risk to motor safety presented by the premature failure of the component. Accordingly, the investigation is closed. To review the ODI reports cited in the Closing Resume ODI Report Identification Number document, go to NHTSA.gov.
- Loss of rearview camera
On June 22, 2020, the Office of Defects Investigations (ODI) opened Preliminary Evaluation PE20-010 to investigate incidents of media control unit (MCU) failures resulting in loss of rearview camera in model year (MY) 2012-2015 Tesla Model S vehicles equipped with the NVIDIA Tegra 3 processor with an integrated 8GB…
On June 22, 2020, the Office of Defects Investigations (ODI) opened Preliminary Evaluation PE20-010 to investigate incidents of media control unit (MCU) failures resulting in loss of rearview camera in model year (MY) 2012-2015 Tesla Model S vehicles equipped with the NVIDIA Tegra 3 processor with an integrated 8GB eMMC NAND flash memory device. EMMC NAND flash devices have a finite lifespan based upon the number of program/erase (P/E) cycles. The subject MCU allegedly fails prematurely due to memory wear-out of the eMMC NAND flash. Tesla used the same MCU with the Tegra 3 processor in approximately 159 thousand 2012-2018 Model S and 2016-2018 Model X vehicles built by Tesla through early-2018. In response to ODI's Information Request (IR) for PE20-010, Tesla provided ODI with 2,399 complaints and field reports, 7,777 warranty claims, and 4,746 non-warranty claims related to MCU replacements. The data show failure rates over 30 percent in certain build months and accelerating failure trends after 3 to 4 years-in-service.According to Tesla, for subject vehicles equipped with the NVIDIA Tegra 3 processor with an integrated 8GB eMMC NAND flash memory device, the eMMC NAND cell hardware can fail when reaching lifetime wear, for which the eMMC controller has no available blocks to recover. With this failure mode, the only recovery available is a replacement of the eMMC device, achieved by physical part replacement of either the MCU assembly or visual control module subcomponent. Tesla provided the effects of MCU failure on vehicle function which result in loss of rearview/backup camera, loss of HVAC (defogging) setting controls (if the HVAC status was OFF status prior to failure.) There is also an impact on the advanced driver assistance support (ADAS) Autopilot system, and turn signal functionality due to the possible loss of audible chimes, driver sensing, and alerts associated with these vehicle functions. There are precedents for addressing defects that result in loss of either backup camera, defogging, or turn signal functions under safety recalls.Tesla has implemented certain Over-The-Air or OTA updates to subject vehicles to mitigate the effects of MCU failure. These updates include firmware changes to reduce memory usage of the subject memory card, improve eMMC error correction and storage management strategies, changing the control logic for turn signal activation, and defaulting the HVAC system to Auto (71.6F) for drives after MCU failure to address windshield defogging. Tesla indicated that the MCU failures are likely to continue to occur in subject vehicles as vehicles continue to operate and use available memory in the 8GB eMMC NAND flash memory until 100% of units have failed. This investigation has been upgraded to an Engineering Analysis (EA20-003). The VOQs associated with the upgrade of this investigation are identified in the attachment to this resume.
- Sudden Unintended Acceleration
On December 19, 2019, NHTSA received a petition from Mr. Brian Sparks requesting that the Agency recall all [Tesla] Model S, Model X, and Model 3 vehicles produced from 2013 to the present due to sudden unintended acceleration (SUA).

On December 19, 2019, NHTSA received a petition from Mr. Brian Sparks requesting that the Agency recall all [Tesla] Model S, Model X, and Model 3 vehicles produced from 2013 to the present due to sudden unintended acceleration (SUA). In his petition and follow-up submissions, the petitioner identified a total of 232 non-duplicative complaints to NHTSA, including 203 reporting crashes. On January 13, 2020, NHTSA's Office of Defects Investigation (ODI) opened Defect Petition DP20-001 to evaluate the petitioner?s request. ODI's evaluation included reviews of all complaints and supporting information referenced by the petitioner, as well as 14 additional complaints to NHTSA related to SUA crash allegations that were either not selected by the petitioner or were submitted after the petitioner's most recent submission. The review also included analyses of available crash data (EDR, Tesla log data, and/or video data) the Agency acquired as part of the evaluation.After reviewing the available data, ODI has not identified evidence that would support opening a defect investigation into SUA in the subject vehicles. In every instance in which event data was available for review by ODI, the evidence shows that SUA crashes in the complaints cited by the petitioner have been caused by pedal misapplication. There is no evidence of any fault in the accelerator pedal assemblies, motor control systems, or brake systems that has contributed to any of the cited incidents. There is no evidence of a design factor contributing to increased likelihood of pedal misapplication. The theory provided of a potential electronic cause of SUA in the subject vehicles is based upon inaccurate assumptions about system design and log data.NHTSA is authorized to issue an order requiring notification and remedy of a defect if the Agency?s investigation shows a defect in design, construction, or performance of a motor vehicle that presents an unreasonable risk to safety. 49 U.S.C. ?? 30102(a)(9), 30118. Since the information before the Agency is not indicative of a vehicle-based defect, it is unlikely that any investigation opened because of granting this petition would result in an order concerning the notification and remedy of a safety-related defect. Therefore, upon full consideration of the information presented in the petition and the potential risks to safety, the petition is denied. The denial of this petition does not foreclose the Agency from taking further action if warranted or the potential for a future finding that a safety-related defect exists based upon additional information the agency may receive.The reference numbers for the complaints to NHTSA cited by the petitioner can be found in the petition submission documents in the public file for DP20-001. Those complaints and the 14 complaints ODI added to its evaluation can be viewed at NHTSA.gov. The reference numbers for the complaints added by ODI are: 11385350, 11383955, 11383233, 11383180, 11378492, 11378458, 11302076, 11299698, 11290006, 11190595, 11174504, 11115496, 11096644 and 11000097. The attached report, further detailing NHTSA?s reasons for denial of the petition, will be published in the Federal Register.
- Battery Management Software Updates
In a letter dated September 17, 2019, Mr. Edward Chen petitioned the NHTSA to initiate a defect investigation of certain Tesla Model S and Model X vehicles that received revised battery management software in one or more over-the-air (OTA) updates from Tesla, beginning in May 2019.

In a letter dated September 17, 2019, Mr. Edward Chen petitioned the NHTSA to initiate a defect investigation of certain Tesla Model S and Model X vehicles that received revised battery management software in one or more over-the-air (OTA) updates from Tesla, beginning in May 2019. The petitioner bases his request on vehicle fires that took place worldwide and OTA software updates Tesla made to the Battery Management System (BMS) of certain Tesla vehicles that resulted in loss of available vehicle mileage range and increased charging durations.On October 1, 2019, the Office of Defects Investigation (ODI) opened DP19-005 to evaluate the petitioner?s request. Information provided by Tesla in response to ODI's information request letter for DP19-005 indicated that a firmware update that may limit maximum voltage was installed in certain MY 2012 through 2016 Model S vehicles (subject vehicles). The voltage limiting firmware is a dynamic algorithm that is enabled in vehicles with high Supercharging use histories, which contributes to high usage stress to the high-voltage (HV) battery. Tesla sold approximately 61,781 subject vehicles in the United States and, through August 2021, the voltage limiting firmware had been enabled in approximately 2,062 vehicles. Through December 2020, ODI identified 59 complaints from consumers alleging reductions in battery capacity (52) or charging speed (7) in the subject vehicles. Log data from these vehicles showed that the voltage limiting firmware had been enabled in about 58 percent (30 of 52) of the complaints alleging range loss. Subsequent updates have restored some or all of the battery capacity to vehicles affected by the voltage limiting firmware coupled with updates enhancing BMS battery brick monitoring algorithms. None of the complaint vehicles have reported any thermal incidents or other safety hazards related to the HV battery.The five non-crash fires referenced in the petition include two fires that occurred in China in early 2019 involving vehicles that: 1) had recently completed Supercharging sessions; 2) were at a high state-of-charge (SOC) of the HV battery; 3) were parked with the battery cooling system shutoff; and 4) had histories of high-stress usage for the HV batteries. The three fires that occurred outside China did not involve the same fact patterns regarding vehicle state and charging history. The two fires that occurred in the United States include one involving a vehicle with no Supercharging history that was driving when the fire occurred and another in which the origin of the fire was external to the HV battery. The fifth fire, which also originated external to the HV battery, involved a vehicle in Germany that had been parked at a low SOC for an extended period. To date, incidents of fires involving parked vehicles with recent Supercharging and histories of high-stress use have only been observed in China, where high-stress use factors appear to be more common. NHTSA is authorized to issue an order requiring notification and remedy of a defect if the Agency?s investigation shows a defect in the design, construction, or performance of a motor vehicle that presents an unreasonable risk to safety. 49 U.S.C. ?? 30102(a)(9), 30118. Given the absence of any incidents in the United States related to fast charging, and the absence of any such incidents globally since May 2019, it is unlikely that an order concerning the notification and remedy of a safety-related defect would be issued due to any investigation opened as a result of granting this petition. Therefore, upon full consideration of the information presented in the petition, and the potential risks to safety, th
