Headlights failing or too dim by model year
What owners say
Upon starting my Honda Odyssey, the dash immediately started saying, Collision Mitigation System Problem, Adaptive Cruise Control Problem, Road Departure Mitigation System Problem, Lane Keeping Assist Problem, Auto High Beam Problem.
Front windshield mounted sensor failure on 2020 Honda Odyssey. Disabled Honda Sensing safety suite which included lane keep assist, adaptative cruise control, auto high beams which all triggered warning messages on the dashboard which all occurred at the exact same time. This problem has been reproduced an inspected by Honda of Frontenac.
Safety mitigation compoments failure that started as intermitent issues and now is consistent. Warning lights come on for Adaptive cruise control failure, Forward collision failure, Lane departure warning failure, high beam failure, lane keep assist failure and others all link back to the DTC U3000-49 internal multipurpose camera unit failure. This compenet failure puts all oppcpants and other vehicles at risk as driver have become reliant on all feature working properly to enhance safety for all. The problem has been diagnose and inspected by two different dealerships. No accident or vehicle comprimised, the camera component just fails and have talked to two other familes that have had same issue. The issues started as a inteitent flsh of all the warning lights and that moved to a constant issue. Currently you can drive the vehicle for a various amount of time and eventually the lights will go on or the dash will be lit up like a christmas tree as soon as you turn it on. Concerned as this is a vehicle that a majority of Moms and kids drive in, as is the case for our familiy.
Multipurpose camera failed. Now I have no cruise control, auto high beam, lane keeping assist, collision mitigation, road departure mitigation.
adaptive cruise control, lane keep assist system problem, collision mitigation system problem, road departure mitigation system problem and auto high beam problem
The monocular collision-avoidance camera 36160-THR-C01 has died on my 2020 Honda Odyssey EX-L. As a result, the following safety features have deactivated causing serious concerns for my safety on the road: ACC problem Collision Mitigation Problem Lake Keep Assist Problem Auto High Beam Problem The car is not even 6 years old and this $1000+ defective camera has rendered my car not up to safety standards.
I am the original owner of a 2020 Honda Odyssey Elite. On July 7, 2026, at approximately 76,127 miles, five safety-system warning messages suddenly appeared simultaneously upon startup: Adaptive Cruise Control Problem, Auto High Beam Problem, Road Departure Mitigation System Problem, Collision Mitigation System Problem, and Lane Keeping Assist System Problem. Restarting the vehicle several times did not clear the warnings. After the vehicle sat for approximately 30 minutes, the warnings disappeared. On July 8, after driving approximately 400 miles home, I parked the vehicle outside in approximately 110-degree heat. About two hours later, upon startup, the same five warnings reappeared simultaneously, along with the Brake System warning light. An authorized Honda dealer confirmed the multiple warnings and performed a DTC scan. Code U3000-49 was stored, indicating an internal failure of the multipurpose camera located behind the rearview mirror. Further testing confirmed that camera replacement was required. The dealer replaced and recalibrated the multipurpose camera at 76,567 miles. The repair cost was $1,631.80 for parts and $717.50 for labor, totaling $2,349.30. I am concerned that failure of a single internal camera component simultaneously disabled multiple driver-assistance and collision-avoidance safety systems. I believe the federal safety agency should investigate whether multipurpose camera failures associated with DTC U3000-49 represent a recurring safety defect in 2020 Honda Odyssey vehicles.
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.
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
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.
