2020 Honda Odyssey Driver Assist & ADAS Problems

5 alerts came on the dash stating lane keeping assist problem , collision mitigation problem , auto high beam problem, forward collision problem and brake system warning. All safety features on my vehicle have failed. I

With no preceding accident or damage, the vehicle suddenly received multiple warning lights on the dash, including: "Adaptive Cruise Control Problem", "Lane Keeping Assist Problem", "Collision Mitigation System Problem", "Road Departure Mitigation System Problem", ""Auto High-Beam Problem", and a Brake System Caution Light. I attempted turning the car off and back on again, disconnecting the battery for 20 minutes, and reconnecting, and checked all fuses that were accessible. It appears the problem is related to the Multipurpose Camera (Honda Part #: 36160-THR-A91-M1). This appears to be a common issue. This manufacturing defect primarily effects safety systems and is common on a car that is primarily marketed towards the transport of families and children. I find this defect to be unacceptable and STRONGLY believe that it warrants a recall by the manufacturer.

Front camera is bad or faulty, triggering all adaptive cruise control, lane keep assist, auto high beam etc errors on dashboard, rendering the car not able to start or die in the middle of the road/traffic when the engine goes into idle mode while stopping at red lights. My odessey has over 111k miles when these issues start showing, but lots of people report experiencing same issue with even with their newer odessey. It doesn’t feel right why Honda installed cheap cameras especially when it plays a crucial role involves safety of the car and the driver.

My vehicle started cycling between all of the check engine types of lights to include the emissions system. When taking it to my local Honda dealership, they determined that it was my front camera (multi-purpose camera internal failure). After some research and speaking to the service department, this major safety failure has been happening to many other Honda vehicles. The emissions system failure seems to also be a faulty design. I feel that the camera system failure could have resulted in an accident or major injury. And of no fault of my own. My vehicle is regularly maintained and is merely 6 years old. I should not be replacing a mayor system like the front camera every 6 years.

The Multipurpose Camera failed. Searches online and discussion with the dealers show this is a common problem. Result is shutdown of collision mitigation systems, blind spot indicators, lane divergence system, auto high beam, etc.

System failure for all of the safety-related assistants. Works intermittently, but mostly indicates failure.

Getting error code for safety sinsing. Lane keep assist, Collision mitigation system and now transmission system. forward facing camera is cause of issue

The front windshield camera completely failed. No longer have emergency braking. Honda said known problem and want to charge $2000 to fix

The multipurpose camera unit failed causing the Forward Collision Warning, Automatic Braking, Lane Keeping Assistance, and Lane Departure warnings lights to come on and rendering all those systems inoperable. Part of the selling point of this vehicle is these additional safety features and for them to fail within 5 years of owning the vehicle is a safety concern. From my own research online, it seems this is a common problem for Odysseys built around this timeframe. This part is extremely expensive and is a required repair if you want the original safety features for the vehicle. I made the repairs, but the life of these units is something that should be looked into.

System is starting to fail by alerting me to clean windshield. Windshield and camera have been cleaned, still getting multiple warnings that system is shutting off safety features during my commutes.

I am submitting this complaint to report a serious safety defect involving my Honda Odyssey equipped with Honda Sensing technology. During normal operation and without any accident, impact, windshield damage, repair, or environmental event, all Honda Sensing safety systems suddenly and simultaneously stopped working. The disabled systems include Collision Mitigation Braking System, Adaptive Cruise Control, Lane Keeping Assist, Road Departure Mitigation, Forward Collision Warning, and related camera- and radar-based features. Multiple warning messages appeared, and the vehicle effectively lost all advanced driver-assistance and collision-avoidance capabilities at once. This occurred without warning and without any action on my part. This failure is extremely concerning because Honda Sensing features are marketed and relied upon as critical active safety systems intended to help prevent or mitigate crashes. A sudden, total loss of these systems materially reduces vehicle safety and places occupants and other road users at increased risk. A safety system that can fail entirely and unexpectedly—absent any triggering event—indicates a potential systemic defect, not routine maintenance or wear. I am concerned this issue may affect other Honda vehicles equipped with Honda Sensing and may be related to a common failure in cameras, radar units, software, or vehicle electronics. I respectfully request that NHTSA review and log this complaint, investigate this failure pattern, and determine whether a defect investigation, service bulletin, or recall is warranted in the interest of public safety. Vehicle details: Make: Honda Model: Odyssey Model Year: 2020 Mileage: 87000 VIN: [XXX] Thank you for your attention to this serious safety matter.

Went to pull into parking lot, ADAS system starting going crazy. Throws transmission malfunction error. Headlights won’t work - they turn on and off or go extremely dim. Van keeps jerking and losing power. Code reader showed U3000-49 electronic failure. Van drove normal, no issues until this code popped up. Issue started 01/08/2026.

After purchasing my 2020 Honda Odyssey EX-L in July 2025 (had approximately 58,000 miles), in January 2026 (current mileage approximately 66,000 miles), it suddenly displayed multiple indicators on the dash, including 'ACC', 'LKAS', 'Brake System', 'Auto High Beam Problem', and 'Collision Mitigation'. My local mechanic indicated the cause was the collision radar system, but it needed to be calibrated at a Honda dealership. My local Honda dealership indicated the problem code as 'U3000-49 Internal Camera Malfunction', necessitating that the multi-purpose camera be replaced. The total repair cost was $2,104.99. Online research shows that this is a common issue with this model year. If the cause is due to a camera malfunction or disrepair, and it impacts the safety of myself and others in the vehicle, why is this not considered a valid reason for a recall? I shouldn't be responsible for a costly repair that didn't result from any mechanical issue or mistreatment on my part. Because of the safety implications, this should be a Honda recall, and I should be reimbursed for the repair cost.

The front-facing camera stopped working, and all associated ADAS systems no longer functioned (Adaptive Cruise Control, Automatic Emergency Braking, Forward Collision Warning, Lane Departure Warning, Lane Keeping Assistance). Several errors needed to be cleared every time the vehicle was started. Our Honda dealership determined that it was a failed Multipurpose Camera (code U3000-49), and that the entire camera unit needed to be replaced and re-calibrated.

My Multi-Purpose Camera System has gone bad after only 5 years. Collision mitigation, cruise control, brake system, lane keep assist, among other safety features are failing because of this.

The tailgate control module has been water damaged and needed to be replaced twice. My local Honda dealership was unable to correct the issue and stated that it is due to a water leak in the frame of the vehicle/tailgate. The dealership has identified the tailgate control module as the cause of the electrical issues causing the battery to die, and advanced safety features to malfunction. Warning lights came on for break system problem, lane departure mitigation system problem, and many other systems all caused by the tailgate control module being water damaged from a leak in the frame.

In December, out of the blue suddenly had rotating list of warning on dash panel (Lane Keeping Assist problem, Collision mitigation system, departure mitigation system problem, auto high-beam problem, Adaptive cruise control problem) plus Brake Warning system light is on constantly and brake hold not working. At first this was intermittent but now on constantly when starting and driving car. Only 55k miles on my Odyssey. Dealer said he had 3 of these in the last three months. Said it was Multi Purpose front camera failure. Cost over $1500. Since huge safety issue putting not only my family but other cars/people at risk, we are paying to repair, however we just found hundreds of people complaining about this same issue. This should be a Honda Recall. We did nothing wrong to cause this safety issue and this part should NOT fail in 5 years. I don't have the final invoice yet but I can upload later if required

2020 Honda Odyssey EX LKAS, Collision Avoidance, Auto High Beam etc. warning lights to cycle continuously. Had my Honda mechanic check problem and Camera Monocular, forward facing camera causing issues and requires replacement. This is only a 5 year old vehicle with 60,000 miles on it! Honda and many used auto parts want upwards of $850 for camera and then as much as $1500 to replace. This is a serious safety issue. None of this vehicles Safety assist items work without this camera.

After researching I find it to be a sensor in the windshield is a common problem

The Multipurpose Camera Unit has failed resulting in loss of Adaptive cruise control, lane keep assist, Automatic braking and other features related to the MCU. There are approximately 6 warnings when starting the car of features not working, and 3 lights that remain lit on the dash including "Brake System". This is the second time this issue has arise. The first time was replaced by the dealer under warranty.
