On October 15, 2026, at about 9:09 AM, I was driving my 2018 Tesla Model S to work. I had the car up to the 65 mph speed limit and let off the accelerator. Instead of slowing down from regenerative braking like it normally does, the car kept speeding up slowly to about 70 mph without me touching the pedal. Regen had stopped working completely. Then an audible alarm went off, the PRND lights on the dash lit up, the screen told me to pull over immediately, and the car lost drive power completely. My work was only about a mile away, so I kept going. After about 30 seconds the alert cleared, power and regen came back, and the car drove normally the rest of the way. When I parked and checked the car's alert log, it showed a long list of battery and drive faults at 9:09 AM: BMS_f003, BMS_f017, BMS_f098, BMS_w003, BMS_w098, BMS_u018 (maximum battery charge level reduced), DI_f137 (unable to drive – pull over safely), and TAS_a218 (air suspension unavailable). The car had installed an over-the-air software update the night before, and this happened on my first drive after the update. The next day, October 16, the car showed new alerts and would not drive: DI_u014 (unable to drive – voltage supply too low), BMS_f107, BMS_w107 (vehicle may not restart), BMS_u008 (acceleration and top speed reduced), GTW_w018, and GTW_w157 (vehicle systems shutting down). It is currently not drivable and parked at my workplace. Tesla ran a remote diagnosis and told me the fault is internal to the high-voltage battery. They quoted $16,232.05 to replace it with a remanufactured pack. The 8-year battery warranty had ended on September 20, 2026, 25 days before the failure, and Tesla declined any goodwill help. My concern: at highway speed the car lost regen, gained speed with my foot off the pedal, then lost drive power completely. In heavy traffic this could easily have caused a crash.

I pulled my Tesla Model S in a parking lot, and as I turned the car into a parking spot, the car suddenly accelerated, jumped the curb next to the parking lot and hit a tree. The car speed when I pulled into the parking lot and then into a parking spot was very low. so I was very surprised and startled to see the car suddenly on its own accelerating and jumping the curb.

Tesla designs a single piece headlight with no serviceable parts. This includes headlights, high beams, and namely daytime running lights. All of these components are on an LED strip that overheats and un-solders due to this high heat, which causes premature failure. Some owners have reported as little as 3 months of life before failing. The daytime running lights are essential for safety driving in low light situations. These daytime running lights are seemingly built to fail. The lights dim then eventually no longer work. Tesla's solution is to have the customer purchase a brand new headlight at $2,500. My vehicle is 2018 Tesla s with 43,400 miles and always kept in carnage. Tesla should either goodwill swap out these headlights for a non-built to fail component, or offer a repair for a quality LED strip with proper heat distribution. Without daytime running lights safety is a major concern on foggy, rainy, and low light situations. I have attached an image showing how the failure begins on top then slowly goes all the way down to the side of the headlight which fails later,.

On February 11, 2026, at approximately 11:00 a.m., I picked up my Tesla vehicle from the Tesla Service Center located at 16955 Chesterfield Airport Road, Chesterfield, Missouri following battery repair. After paying for the service and being told the vehicle was ready, I discovered in the parking lot that the hood was not latched and was misaligned. The hood had been opened during service. Prior to drop-off, the hood latched properly and securely. Releasing the vehicle in this condition created a significant highway safety hazard. At highway speeds, an unlatched hood can deploy and completely obstruct forward visibility, potentially resulting in a catastrophic collision. When I immediately reported the issue to service management, responsibility was dismissed and attributed to a prior front collision history, despite the hood functioning normally before service. The service center did not promptly correct the unsafe condition. I was forced to leave the premises, purchase mechanical tools across the street, and physically resecure/realign hinge hardware myself in order to safely operate the vehicle. I have preserved video documentation of the hood condition at the time of release, along with service records and receipts. This represents unsafe post-repair vehicle release and failure of final safety verification. I have video evidence of my vehicle after I paid $1170 service fee and inspected the hood not latching. It was too big to attach but I am more than willing to put on a flash drive and send. please call me and instruct where to send it. Thank you.

Steering the vehicle is extremely difficult leading to major safety concerns. When making turns, right or left, where the steering wheel travels greater than 90 degrees, the steering wheel becomes hard to push past that 90 degree mark (I am 6' 200lb man). Once past 90 degrees, the wheel will stay…
Steering the vehicle is extremely difficult leading to major safety concerns. When making turns, right or left, where the steering wheel travels greater than 90 degrees, the steering wheel becomes hard to push past that 90 degree mark (I am 6' 200lb man). Once past 90 degrees, the wheel will stay at that turning angles without correcting to straight. A few times I have had to "muscle" the steering wheel quickly back the opposite direction to keep from running into parked cars on the right side on a right turn. I appears the lower steering column U-joint has rusted and is binding every 90 degrees making steering unpredictable, dangerous and difficult altogether.

My 2018 Tesla Model S has a recurring safety-critical defect involving the steering system and the Chassis CAN communication network. On October 20, 2025, the vehicle had to be towed to a Tesla Service Center because it would not power on and displayed multiple safety alerts (traction control disabled, stability control disabled, ABS disabled, and reduced steering assist). Tesla documented that the steering rack was “bringing down the Chassis CAN” and stated the issue might require a new steering rack and coolant pump if it returned. The warnings have now returned, and the vehicle is again showing active alerts for disabled traction control, disabled stability control, and previously reduced steering assist. This is a repeat of the same unsafe condition that Tesla attempted to repair. The car is unsafe to drive and could cause loss of steering control. This is a recurring steering/Chassis CAN failure with major safety system disablement. I am reporting this because the defect affects vehicle control and increases the risk of a crash.

The contact owns a 2018 Tesla Model S. The contact stated that whenever the rear door was opened, the window on the door rolls down approximately a half inch, and whenever the door was closed, the window automatically rolled back up. The contact stated that after the rear door was opened to place some leftover dinner in the rear seat, the contact closed the door and his finger was caught in between the window and the door frame. The contact was concerned and stated that there should be a sensor to prevent such a failure and any injury while closing the door. The contact stated that his finger was bruised and cut and was bleeding profusely. The contact removed his finger as quickly as possible, preventing even more injuries to his fingers and hand. Medical attention was not needed; however, the contact did clean and bandage the finger after arriving to the residence. The dealer was not informed of the failure. The manufacturer was not made aware of the failure. The failure mileage was approximately 110,000.

Our doors completely locked inside our garage. We could not get in the car at all, even after a technician came to replace the low voltage battery. Only after replacing the low voltage battery was someone able to get into the car. However, that low voltage battery did not fix the core issue the car was having. It was a current leak in the high voltage jumper harness. This issue required us to get a very expensive tow of our car out of our garage (required dollys & a winch), and then a very expensive diagnosis & repair by Tesla. These doors should have a way to open if the car's battery or other electrical system malfunctions.

On [XXX], I was driving my recently purchased 2018 Tesla Model S (VIN: [XXX], mileage approx. [30,536]). The vehicle was purchased directly through Tesla’s app in late August 2025 and delivered to me the same day of the incident. Approximately 4.5 hours after delivery, while driving with my son, white smoke began to come out of the cabin air vents. Within minutes, the smoke turned black and rapidly filled the interior of the car. I immediately pulled over and evacuated the vehicle with my son. Shortly after, the car caught fire and was completely destroyed. No modifications had been made to the vehicle, and it was sold to me as inspected and certified by Tesla. The sudden appearance of smoke from the vents and rapid escalation to a full vehicle fire posed a severe danger to me, my child, and others on the road. I am reporting this to NHTSA to document the incident and to request that the agency investigate whether Tesla Model S vehicles have underlying defects that may cause dangerous cabin fires shortly after use.

On [XXX], my 2018 Tesla Model S (VIN [XXX] ) experienced a complete brake system failure while in motion. The brake pedal was pressed multiple times, but the vehicle did not stop, resulting in a collision. The emergency brake also failed to engage. 1. Component/System Failure: The braking system, including both the standard hydraulic brakes and the electronic emergency brake, failed to operate. The vehicle is available for inspection upon request. 2. Safety Risk: This put my safety and the safety of others at immediate risk, as I was unable to stop the vehicle to avoid an accident. 3. Confirmation of Problem: The problem has not yet been reproduced or confirmed by a Tesla service center since the accident, but the vehicle previously had recalls in 2021 and January 2024 for brake and emergency brake issues that Tesla claimed to have remedied. 4. Inspection: The vehicle has been involved in an accident and has been documented by police and insurance representatives. Tesla has not yet inspected the car after the most recent failure. 5. Warning Lamps/Messages: There were no warning lamps or error messages on the dashboard prior to the failure. The brakes appeared normal until the moment they failed completely. This incident demonstrates that the recall-related brake defects remain unresolved and present a serious safety hazard.

I own a 2018 Tesla Model S. While it was still under warranty the passenger side door handle quit working and it was no longer possible to open that door. Tesla replaced the door handle at no change with a newly designed mechanism. It was explained to me that they redesigned the mechanism which had a high failure rate, and my car handles would no longer be installed in later cars. I asked if they would change all 4 door handles for me, and was told they would not. Now several years later, another door handle has failed. This time dangerously. The door pops open spontaneously, and therefore the car is not safe to drive. I have an appointment for repair, but at full cost. Should Tesla not cover the cost, as it makes the vehicle unsafe to drive, and they clearly knew about it when they originally sold me my car?

In July 2024 all the cameras on the Tesla Model S except the rear stopped working after a failed software update. This meant that all of the driver assistance systems as well as GPS, adaptive cruise control, blind spot monitoring, lane departure warning, forward collision warning etc stopped working. The lack of availability of this system meant that the car no longer had any advanced safety features that came with the car. It took many months for Tesla service to diagnose and fix the problem, which they identified as a failure of the Auto Pilot computer. After I was finally able to get an appointment with the Service center, they replaced the Autopilot computer at a cost of over $1500. The failure first appeared in July 2024. The symptom was GPS location being stuck and Autopilot and all safety features being not available.

While driving both North (in the evening) and also South (in the morning) on [XXX] between Washington, DC and Richmond, VA I have experienced an issue with Tesla’s Auto Pilot that can be very dangerous and scary. While using the navigation system and with Auto Pilot on while in the left most line on this divided highway, the car made multiple attempts to steer into the Express Lanes even when the large gates are closed and the red lights are on to indicate that the Express lanes are closed in the direction of traffic. To counteract this, it is necessary to quickly take control of the steering wheel and to get it to cancel Auto Pilot, otherwise the car would go into the gates and cause an accident. This has happened to me several times when I was traveling in the left most lane and when the gates were closed. This happened in November, December and in January. The system has not learned to handle this situation and to avoid steering into the barriers. I reported these incidents to Tesla’s Support Team by phone and after several weeks I received a phone call whereby the local service center (Rockville, MD) called me. Josh, the person that called me read a lengthy text to me that essentially reviewed the driver’s responsibilities when using Auto Pilot. I asked if there was any indication that they will work on fixing this issue and I was told that the explanation I got (which was no explanation at all, just a reminder of driver responsibilities) was the entire response. I informed him that I would report the incident to NHTSA. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

•I’m not sure what component was responsble for either the braking issue or the fire. It is available for inspection. •When driving the brake pedal had a frightening delay that almost caused 2 accidents and unfortunately my car was charging on the 24th of October which could have something to do with arching that led to my garage catching fire rendering the car unable to move or turn on after the incident. I’ve insisted Tesla insurance to look into possible causes because the Fire dept. mandated the a LADWP (power company) to install new transformers to our power supply a couple of days after the fire, which they did. Tesla insurance seems uninterested in finding the cause and wants to compensate me for the vehicle but I believe it’s in their best interest to find a cause and document it. The car had no issues prior, in fact the service center sent a mobile tech to replace the 12volt battery on the car not even 10 months ago. After the fire the car died and has a bunch of codes that make it inoperable. • Service center rejected looking at it because of the risk. They said since it was possible salvage they could not look at it which is understandable but they worked on it before in decem •Insurance has been unwilling to look at any of this they just want pictures of the car to settle the issue. In my opinion they are ignoring a bigger problem. Tesla is my insurer. •The car had no issues prior to the fire and none during the near misses were the brake delayed.

While driving in Autopilot mode, approx 70 mph in light rain the vhicle began to drift side to side almost crossing over the lane dividing line. Upon grabbing the wheel to take control the vehicle entered multiple 360 degree spins crashing into "K" rail. In the past I have noticed when taking control of the vehicle from Autopilot the wheel jerks.

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)"…
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.

- Compliance with Standing General Order 2021-01 Reporting Requirements
The Office of Defects Investigation (“ODI”) has identified numerous incident reports submitted by Tesla, Inc.

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. According to Tesla, Summon is a short-distance SAE Level 2 system, controlled by the user from a cell phone…
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. 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…
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.
- Sudden Unintended Acceleration
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 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. Attached to the Petition is a paper authored…
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 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.

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.

- Tesla Passenger Play
The Office of Defects Investigation (ODI) opened Preliminary Evaluation (PE21-023) on December 21, 2021, to evaluate the driver distraction potential and use frequency / circumstances of in-vehicle game-play functionality referred to as ?Passenger Play? in certain model year (MY) 2017-2022 Tesla Model 3, S, X, and Y…
The Office of Defects Investigation (ODI) opened Preliminary Evaluation (PE21-023) on December 21, 2021, to evaluate the driver distraction potential and use frequency / circumstances of in-vehicle game-play functionality referred to as ?Passenger Play? in certain model year (MY) 2017-2022 Tesla Model 3, S, X, and Y vehicles. Distracted driving can result in an increased risk of a crash. PE21-023 was prompted by the receipt of Vehicle Owners Questionnaire (VOQ) 11439598 from the owner of a 2021 Model 3 on November 6, 2021. ODI sent an Information Request (IR) letter to Tesla on January 20, 2022 and received Tesla?s response on March 4, 2022.On December 24, 2020, Tesla introduced Passenger Play to vehicles equipped with the Intel Atom processor (receiving an aftersale software update) via its 2020 holiday release. Passenger Play permitted occupants to play specific games selected by Tesla for primarily turn-based play style and limited gameplay motion with the transmission in Drive and the vehicle in motion. Under these conditions, a notification would display on the screen and the screen area devoted to the game would reduce from 100% to accommodate vehicle controls and driving task data readout. Specific changes varied among models. On December 21, 2022, Tesla voluntarily disabled Passenger Play capability with Firmware Release 2021.44.25.1 in response to NHTSA?s request. Tesla reported a month later that a 97% completion rate was achieved though Tesla?s Over the Air (OTA) update. ODI opened PE 21-023 to evaluate the driver distraction potential of Tesla Passenger Play while the vehicle is being driven including aspects of the feature, frequency, and use scenarios.Based on the analysis conducted, PE21-023 has been closed. The closing of this investigation does not constitute a finding by NHTSA that no safety-related defect exists. Furthermore, it does not foreclose the Agency from taking further action, if warranted, or the potential for a future finding that a safety-related defect exists through additional information the Agency may receive.See attached Closing Report for a detailed summary of the investigation findings.
- 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.
- 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
