2020 Honda Pilot

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.

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.

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.

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.
