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 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.
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.
The camera controlling many systems regarding safety failed and caused numerous warning lights to come on. Complete camera replacement was necessary.
All of the warning lights shows up on the dash board. Honda told me it’s related to a bad multi purpose camera. None of the safety features or cruise control will work until the camera is fixed.
The multipurpose camera in the vehicle failed, causing multiple warning lights to come on related to the collision warning, blind spot warning, lane keep assist, lane departure warning, adaptive cruise control, and others. The dealership said it needed to be replaced, as it was no longer working and none of these features would work without replacement.
The entire advanced driver assistance system failed. My vehicle has not been inspected. The entire adas does not work upon startup.
September 2024, I bought my car to the dealership to check multiple warning lights showed up on my dashboard. The dealer read the code and determine the multipurpose windshield camera had internal malfunction. The dealer told me that my multipurpose windshield camera need to be replace on my 60k mi 2020 Odyssey ex-l for ~$2. 3k in conshohocken PA. I had many of those sensor lights on (e. G. Acc, lane assist, collision mitigation) and saw many comments on a youtube video (Honda Odyssey warning lights bonanza get ready to pay). Do my research online; seem like this happened a lot for the Honda Odyssey from year 2017 to year 2020 hope NHTSA will investigate on this issue. It a very expensive fix for the vehicle barely break in. With all those safety feature disengage/malfunction at the same time, it is a very dangerous issue.
