The front facing camera failed. Cruise control doesn’t work. Emergency braking doesn’t work. Lane departure warnings and lane keeping assistance doesn’t work. Forward collision warning doesn’t work. The forward facing camera failure was confirmed by an independent mechanic. Warning lights in the driver’s display show that the safety features are not working.
On October 7, 2026, at approximately 131,425 miles, my 2020 Honda Pilot Elite suddenly displayed multiple Honda Sensing safety-system failures simultaneously without prior warning. The vehicle displayed Adaptive Cruise Control Problem, Lane Keeping Assist Problem, Collision Mitigation System Problem, Road Departure Mitigation System Problem, and Auto High-Beam Problem. I shut the vehicle completely off and restarted it, but the warnings returned. These failures appear to disable multiple advanced driver-assistance and collision-avoidance functions at the same time. I have found reports from other 2020 Honda Pilot owners describing similar simultaneous Honda Sensing failures, including reported failures of the multipurpose forward camera. I am having the vehicle diagnosed and will retain the diagnostic trouble codes and repair information. I am reporting this because the simultaneous loss of multiple collision-avoidance and driver-assistance safety systems appears to be a potential safety-related defect.
Honda Pilot 2020 sensing multipurpose camera failure. DTC U3000-49
When driving in normal conditions on a 2 lane road and passing oncoming vehicles the ‘auto emergency brake’ will flash on screen and briefly slow/attempt to apply brakes. Very intermittent, no consistency with other conditions such as weather, traffic flow or driving conditions. Concern - safe driving conditions are interrupted causing driver distraction and higher risk of accident.
My front sensor camera has malfunctioned which is causing numerous failing safety systems such as lkas, adaptive cruise control and automated braking.
I own a 2020 Honda Pilot with approximately 85,000 miles. While driving, the Adaptive Cruise Control (ACC) and Collision Mitigation Braking System (CMBS) warning lights intermittently come on, causing these Honda Sensing safety functions to become unavailable. The warnings sometimes disappear and the systems operate normally again, but the problem continues to return. The vehicle was diagnosed with DTC U3000-49, Multipurpose Camera Unit Internal Electronic Failure. I took the vehicle to a repair facility and was advised that the multipurpose camera needs to be replaced, with an estimated repair cost of approximately $2,200. The repair facility also told me that they have recently seen other Honda vehicles with the same or very similar issue. They had a Honda Odyssey with a similar Honda Sensing/camera problem just before my Pilot. I am reporting this because the failure occurs while driving and disables ACC and CMBS. I am concerned that similar multipurpose camera failures may be occurring in other Honda Pilot and Odyssey vehicles.
Multipurpose Camera Unit Failure, causing many warning symbols on dash.
Front facing camera fail. Causing brake system adaptive cruise control, lane keeping assist , collision mitigation, road departure mitigation. Auto high beams to not work
After previously reporting that a connecting rod bearing noise developed after the timing belt maintenance package was performed near 100,000 miles, the connecting rod bearings failed around 3,000 miles later while going down the interstate with children in the car. Thankfully the Pilot, which was shaking and making noise, was able to be pulled over to side of the interstate and later towed to the dealer service. No symptoms other than the noise at low speeds usually from take off, which regional Honda said wouldn’t damage anything, but apparently it did.
There is significant rust on the frame and undercarriage of the vehicle. There has been no actual safety concerns yet, but it may lead to severe issues if unaddressed. It has since an active recall exists for the corrosion of the rear subframe. A specific rust-related inspection is on hold until I receive further direction from the dealership I purchased the vehicle from.
The contact owns a 2020 Honda Pilot. The contact stated while driving at an undisclosed speed, the vehicle hesitated while accelerating and was shaking violently. The contact associated the failure with the transmission. The manufacturer was notified of the failure and offered a goodwill repair; however, the contact had not agreed to the terms. The vehicle was taken to the dealer and the dealer confirmed that the transmission needed to be replaced. The contact stated that prior to the transmission failure, the vehicle was taken to the dealer for the hesitation issue, and the dealer associated the failure with the transmission. The vehicle was not repaired for personal reasons.
I got in the car one morning and had 5 error codes come on and they have not gone off. None of the driver assist controls are working. The cruise control does not work either. All of the dash lights are on. Toyota determined it is the front camera that failed and repair would be $2000. Car is available for inspection anytime. Unable to drive for long periods as the cruise control does not work. The lane assist option does not work. The automatic break system does not work. Half of the option this car came with do not work.
While driving on my way home from work (24 mile drive) I received on my dashboard faults that flashed briefly for my steering, lane keeping assistance, lane departure, forward collision, automatic emergency braking, adaptive cruise control and parking collision (warning lamps). My radio also had cut out at the same time. While that occurred my steering wheel jerked suddenly while going straight at speeds around 60mph. I brushed it off as a communication issue since it is known to occur on these vehicles, but the steering wheel jerking was new to me. Made it home turned the vehicle off (vehicle was off for 15 minutes). I started up the vehicle no warning lamps came on. But as soon as I got up to 40mph and a mile from my home the same issue occurred but more frequent, but less of the steering wheel jerking. I got where I needed to go and got back onto the road and reached 30 mph the warning lamps came on more a lot more frequently on my way home. As soon as reached my alleyway turning left, the steering wheel had a moment of locking up (about 5-10mph). This came as a shock for me. I backed up into my garage and had to turn the steering wheel left again and the same thing happened. I parked the while the vehicle was running I turned the steering wheel really fast, recreated the steering wheel locking momentarily a few times. I turned the vehicle off and tried to restart it but there was no power. Turns out that my battery had gone bad. I had no indication of a low voltage or battery issue. I replaced the battery and issue was resolved. For me and a situationally unaware driver and this issue occurs where the steering wheel jerked and/or an emergency evasive action was needed, this could cause an accident due to the sudden loss of steering. There was no indication of battery issues. No dealer or independent shops were involved. I am a mechanic myself.
There's an old recall called FAKRA Service Cable Safety, Recall Number #23V-431, The recall issue was fixed, but it is now recurring. The cracking windshield sound, along with the screen shutting off or going blank, increases the risk of a crash or injury when backing up or driving while using the navigation system. We contacted Honda about this issue, but they don't seem keen on fixing it, especially now that it's out of warranty.
All safety alerts started showing as the forward camera has an internal failure as diagnosed by the dealer
While driving the vehicle on a family trip all of the driver assist functions shut off. Cruise Control, Lane Assist, etc. Numerous warning lights were triggered including brake system. Most noted the various driver assist functions became disabled. We had the vehicle codes read by a couple non-dealer locations. The OBD readers indicted that everything was fine with no codes being presented suggesting an error. Vehicle could be driven but none of the standard safety features with the camera system worked. Took it to Honda Dealer (Honda Marysville, Ohio) who performs all service on the vehicle. They concluded a faulty main camera and noted there were no recalls attributed to the device. Information we researched suggests these Camera's should last the life of the vehicle or at least 10 years. This car's windshield has never been replaced, and the car spends 75% of it's time in a garage. All mileage on the vehicle is highway mileage. Researched information suggests changing the windshield or subjecting cameras to extreme heat (sitting in sun all day, every day) can result in damage but this car was not subject to any of that from it's manufacture. Online forums suggest this issue is impacting both Honda Pilot's and Honda Ridgeline, with a lot more complaints on the Ridgelines. I have all paperwork from Honda and requested the part be returned to us for which Honda complied. No accident occurred as a result of the faulty camera.
Tachometer is starting to surging idle. Getting a wave of errors lights and messages. It’s also a known problem on the 2019 of the same model and it has a recall. I received the same code from an auto repair shop. Service Bulletin 21-010

I am reporting a severe safety defect regarding the automatic transmission on my 2020 Honda Pilot AWD (VIN: [XXX]). The vehicle experiences a violent and constant transmission vibration/judder under light throttle acceleration. On XXX, at 127,073 miles, an authorized Honda dealership officially diagnosed the vehicle under Repair Order # XXX, confirming the presence of "shudder at light throttle". Despite changing the transmission fluid as required by maintenance schedules, the issue persists. This failure causes unexpected vehicle hesitation and jerky shifts while driving at highway speeds, creating a high risk of rear-end collisions and posing an immediate safety hazard to my family and other drivers on the road. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
Summary of safety defect and failed recall repair: Vehicle: 2020 Honda Pilot EX (Clean California Title) Core Issue: Persistent, catastrophic failure of the MOST Bus fiber-optic communication network, resulting in complete blackout of the federally mandated rear backup camera (FMVSS No. 111 violation), total infotainment reboot loops, loud audio cracking/popping, and instrument panel system failure during active vehicle operation at 65+ mph highway speeds. RECALL REMEDY FAILURE CHRONOLOGY: 1. IN-WARRANTY ANCHOR: On April 20, 2022 (34,201 miles) at Tracy Honda, initial network cracking/popping and communication faults were logged under factory warranty. Display head unit was replaced, but underlying MOST Bus backbone issues persisted. Fakra connectors replaced to attempt to fix the issue. 2. RECALL ATTEMPT: On July 17, 2025, at Lompoc Honda, the vehicle was presented specifically under Safety Recall Campaign 23-047 / NHTSA 23V-431. Dealer technicians installed FAKRA connectors and connector jumpers per official remedy instructions. 3. REMEDY FAILURE: The recall remedy failed to correct the defect. The vehicle continues to experience "Network Communication Lost" and "Check Tuner" system collapses, completely disabling the rear backup camera display without warning - all while being in a 10-minute reboot loops. SAFETY HAZARD: The sudden, unannounced loss of rear visibility and screen blackout creates a direct backover and collision hazard in violation of Federal Motor Vehicle Safety Standard No. 111. Furthermore, total network reboots at highway speeds cause severe driver distraction. REMEDY REQUESTED: American Honda Motor Co., Inc. has been notified (Corporate Case #XXX), but has failed to remedy this known federal safety defect after statutory repair opportunities. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
Full brake system, Emissions System problem, and Service System malfunctioning, out of the blue. Factory Reset and System Updated performed with no improvement.
The contact owns a 2020 Honda Pilot. The contact stated that after starting the vehicle, there was an abnormal ticking sound coming from the engine. The vehicle was taken to the local dealer, who examined the engine and discovered metal shavings inside the oil pan and there was engine rod bearing damage. The contact was informed that the engine needed to be replaced. The vehicle was not yet repaired. The manufacturer was notified of the failure, but no assistance was provided. The contact was informed of NHTSA Action Number: PE25008 (ENGINE). The contact stated that the vehicle had experienced the failure listed in the NHTSA Action Number. The failure mileage was 46,500.
Engine start/stop function fails to restart after automatically shutting off at a light or in traffic. It falters and fails to start, then the dashboard lights up with errors, and I have to put it into park before restarting. Sometimes it takes a few tries before restarting. The battery has been replaced twice in the last year and the starter motor within the last year too, but the issue persists.
When the vehicle is at a stoplight or stop sign, the engine regularly shuts off. The engine does not automatically restart and sometimes it takes several minutes to restart the engine, leaving the car blocking traffic at a light. This happens REPEATEDLY and often.
NHTSA’s Office of Defects Investigation opened these reviews into vehicles including this one.
The Office of Defects Investigation (ODI) has received 414 reports of connecting rod bearing failures in the 3.5L V6 engine used in the following vehicles: Model Years (MY) 2018-2020 Acura TLX, MY2016-2020 Acura MDX, MY2016-2020 Honda Pilot, MY2018-2020 Honda Odyssey, and MY2017-2019 Honda Ridgeline. The subject engine failures were analyzed as part of a Recall Query (RQ24013). It was determined that these engine failures are outside the scope of Honda Recall 23V-751. Further, evidence gathered in conjunction with RQ24013 does not suggest this failure is caused by the same crankshaft manufacturing defect that is addressed by Honda in Recall 23V-751. Based on analysis of data from RQ24013, NHTSA has closed that investigation. The significant number of reports of engine failure in vehicles outside the scope of RQ24013 presents a potential safety risk that warrants further investigation. ODI is opening this Preliminary Evaluation (PE) to further evaluate the scope and severity of the potential problem and to fully assess the potential safety-related issues. To review the ODI reports cited in the Opening Resume ODI Report Identification Number document, go to NHTSA.gov.
On June 3, 2022, the Office of Defects Investigation (ODI) opened Preliminary Evaluation PE22005 after the agency received VOQs and several field reports concerning the Auto Idle Stop (AIS) feature on 2016-2019MY Honda Pilot vehicles. The complaints allege that the engine fails to restart on its own from a complete stop at a traffic light or road intersection with the AIS function engaged. The subject vehicles are equipped with a 3.5L engine with a 9-speed automatic transmission. On January 6, 2023, Honda released service bulletins 23-008 and 23-009. These service bulletins address the failure to restart issue in the 2016-2019MY Honda Pilot vehicles, as well as the 2015-2020 Acura TLX, 2016-2020 Acura MDX, 2019-2022 Honda Passport, and 2020-2023 Honda Ridgeline vehicles. The repair outlined in the service bulletins is a two-stage countermeasure to remedy the issue. The first stage is a Programmed Fuel Injection (“PGM-FI”) software update. The second stage is only deployed if the software update fails to remedy the issue. The second stage, depending on the model and model year, consists of replacement of the starter assembly, starter relays, and a valve adjustment. Additionally, Honda extended the warranty coverage to 10 years with unlimited mileage for vehicles requiring the second stage component replacement. ODI continues to receive complaints of the AIS failure to restart, with many complainants alleging the campaign countermeasures had been completed.NHTSA has reviewed Honda's Information Request Letter responses involving warranty claims, lawsuits, and consumer complaints in addition to ODI's own data. This Engineering Analysis is being opened to further consider the potential safety defect, including gathering additional data regarding Honda’s service campaign efficacy. ODI is additionally expanding the scope to encompass all vehicles addressed in Honda’s service bulletins 23-008 and 23-009 as well as newer model year vehicles, which are substantially similar to the vehicles covered by the service campaign. To review the ODI reports cited in the Opening Resume ODI Report Identification Number document, go to NHTSA.gov.
On November 8, 2024, the Office of Defects Investigation (ODI) opened Recall Query RQ24013 to assess the scope of Honda recall 23V-751 after receiving complaints that alleged connecting rod bearing failures in vehicles that were not within the scope of recall 23V-751. In November 2023, Honda recalled 248,999 various Model Year (MY)2016–2020 Honda and Acura vehicles equipped with the 3.5L V6 engine. Honda recalled these vehicles due to a crankshaft manufacturing defect that caused premature connecting rod bearing wear and engine seizure. While the out-of-scope failures involved in these complaints appear to have a very similar failure mechanism as the recalled engines, a thorough analysis of all available data from Honda has not indicated that the same manufacturing defect exists in the out-of-scope engines as the engines recalled by 23V-751. Based on this analysis ODI has determined that Honda has properly defined the scope of recall 23V-751. Consequently, ODI will close this RQ investigation. NHTSA will continue to investigate these complaints of engine failure as part of a new Preliminary Evaluation Investigation (PE25008). The Agency reserves the right to take additional action if warranted by new circumstances.
