The forward facing ADAS camera has been reporting U0104 error. This resulted in many advanced safety features failing, including adaptive cruise control, automatic emergency braking, forward collision warning, and lane departure warnings. The problem was confirmed and repaired by a independent service center. The problem first appeared on June of 2026
2020 Honda Odyssey driver assistance complaints

My van is suddenly giving me warnings that include collision mitigation, road departure mitigation, adaptive cruise control, lane-keep assist, brake hold system, and traffic sign recognition. My safety is at risk if the front camera system is not working/faulty. I was unaware of the problem and had my cruise control on when it just went off and there were warnings popping up on dashboard. There was a class action lawsuit filed against Honda on 7/2/26 in CA for certain Honda vehicles. I have had my van put on a computer that has given us the error code and is a front camera failure. The issue first appeared on 7/2/26. It will suddenly start flashing warnings when I’m Driving. It will also flash warnings right after I start the vehicle.
I purchased my 2020 Honda Odyssey Brand new in California. On 6/27/2026 upon starting the vehicle up in the morning there was a myriad of warning messages that came up on the cluster for the first time out of the blue. The battery was replaced a few months ago with a new one and no MIL lights were illuminated prior to this morning. Now an amber BRAKE SYSTEM tell tail symbol is illuminated on the cluster. 1: Adaptive C.C. problem 2: Auto high beam problem 3: Collision mitigation braking system problem 4: Lane Keep Assist problem 5: Road depature mitigation problem The vehicle still is able to run and drive, but none of these standard vehicle safety features are working as expected. I can't even apply cruise control now. On each key cycle the error messages come back up, and when driving they also stay in the center of the cluster and make annoying dinging sounds. I disconnected the battery ground cable from the chassis for 15 min and reconnected, but the errors come back on instantly once the van is started up. With my OBD scanner, there is a code being set U0104-00. I have not paid yet to have the van inspected formally by the dealer.
Multipurpose camera is defective- broken after only 80,000 miles. No longer functions at all. No automatic emergency braking, no forward collision warning, no lane departure warning, no lane keeping assistance, no adaptive cruise control. Dangerous now without all those computer controlled safety functions. $2400 replacement. I don’t have $2400.
one morning randomly multiple warnings turned on on the dashboard of my 2020 honda odyssey . the following warnings turned on and have stayed on since: Adaptive Cruise Control Problem, Lane Keeping Assist Problem, Collision Mitigation System Problem, Road departure Mitigation Problem, Auto High-beam problem, and Brake System. This appears to be a common issue when searching online and appears to be a sensor issue.
Forward Camera Not Working. Because of camera defect the following safety features are not working Adaptive Cruise Control Automatic Emergency Breaking Forward Collision Warning Lane Departure Warning Automatic Head Lights
The ADAS system doesn't work. The forward collision system, adaptive speed control, and lane keeping assist have all shown malfunction errors and no longer work.
The warning messages keep popping up regarding the lane assist system, Adaptive cruise control not working and dealer states that the camera needs replacement and this is common issue for most Honda cars so should be recalled
Vehicle suddenly starts having multiple lights and warnings come up such as road departure mitigation, adaptive cruise problem, collision mitigation, auto high beam, etc. reading online it seems multiple people with honda oddysey are experiencing the same issues.
The blind spot system was a problem when I purchased the car, it spent 15 days in service in the first 30 days of ownership to address the issues. Now, I after another light came on I discovered 9 open recalls on the vehicle that were not disclosed prior to purchase.
While driving the vehicle under normal conditions, multiple advanced driver assistance and safety systems suddenly became unavailable without warning. The systems affected include Automatic Emergency Braking, Forward Collision Warning, Lane Keeping Assistance, and related safety features that rely on the forward-facing camera. The failures occurred at the same time and were indicated by warning messages displayed on the instrument panel. The vehicle was inspected by an authorized dealer, who confirmed a diagnostic trouble code indicating an internal electronic failure of the forward multipurpose camera. The failed component is installed behind the windshield and is available for inspection upon request. The dealer stated that no accident, physical damage, misuse, or external cause was identified. After the camera failure was identified, the vehicle also briefly displayed a transmission system warning message that later cleared on its own. In addition, the center display screen has shown unstable behavior while driving, including unexpected resets and flashing back to the navigation screen. The sudden loss of collision mitigation, lane assistance, and warning systems reduces the vehicle’s ability to assist in avoiding crashes, particularly in emergency situations, and increases safety risk to the driver, passengers, and others on the road.
We went to a car wash and that day after the car wash we started getting 6+ error message codes for adaptive cruise control, lane assist, lane departure, blind spot, rear cross traffic, etc. our tech that we took it to says they have seen this happen nation wide on these vehicles
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
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.
The radar is broken leaving all ADAS unusable in addition to no option to use cruise control.
After being on idle on a stop light, when releasing the brake to go, warning on dash says "Collision Mitigation Warning" when nothing hit the car and I'm there's enough distance with the car in front and behind. The severity has increased now, after being idle, when releasing the brake, it now completely shuts off, dash says "Shift to Park", and can't go, unless I push the ignition button. Took it 3x for the same errors on dash, Honda said the 1st time it was low battery, battery was running on low juice and didnt have power to come back from idle, they changed the battery. Now they say they need to replace the starter after few thou$and$. I see online this happening to others too. I fear the car behind me, may rear end me, because I can't go, green light is on, but I can't move as I'm re-starting the vehicle after being on idle. Honda says my VIN is not part of the bad batch. It's happening more frequently and Honda said they were able to replicate.
Vehicle has all time on the brake system, front collision, auto high beam, adaptive cruise control, lane keeping assist abd road departure warnings. Sometimes the vehicle turns off suddenly when stop, and the steering wheel gets hard when parking.
Basically, numerous errors lite up the dashboard. But the car itself was running ok mechanically. I took it in for service and after a couple of non sensical diagnoses. It was determined to be the multipurpose camera in the windshield area. And they want two thousand dollars to fix it. I know most people purchased a vehicle like this in order not to encounter repair bills like this (that aren’t the engine). A simple and obsolete electric should be pretty simple to swap out.
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.
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.
Camera is faulty. Many owners report a similar problem.
The front windshield camera completely failed. No longer have emergency braking. Honda said known problem and want to charge $2000 to fix
The front camera that controls adaptive system died within 4years of owning the vehicle so all the warning lights come on now.
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.
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 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 multipurpose camera module has failed, on the vehicle resulting in the simultaneous loss of several driver-assistance and safety systems while the vehicle is in operation. These systems include cruise control, lane keep assist, lane departure warning, collision mitigation, automatic high beams, and the brake system warning. Upon inspection, there appears to be overheating within the camera module. This overheating has caused visible discoloration both inside and outside the module housing. Based on these observations, I believe the condition may present a potential fire hazard. Additionally, the plastic cover mounted to the windshield becomes extremely hot to the touch, creating a risk of skin burns if it is accidentally contacted. This malfunction poses a significant safety concern for my family. If the camera fails while driving, the vehicle’s safety systems may not function as intended, increasing the risk of an accident. All of the failures chime in one after another displaying a problem with the malfunctioning components stated earlier in the text. Furthermore, if a driver is deaf or not actively monitoring the instrument panel or speedometer, they may not hear or immediately notice the warning alerts indicating that these systems are no longer functioning. The issue has been diagnosed by my local repair shop finding error code U3000-49: Camera/Radar Internal Failure. Repair requires replacement of the multipurpose camera module, with an estimated cost exceeding $2,000 in parts and labor, which represents a significant financial burden.
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.
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.
