There are 4 owner-reported speed control & cruise complaints for the 2020 Honda Odysseyin NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
While driving on 12/20/2024 the 2020 Honda Odyssey started showing 5 warning lights (ACC, LKAS, Collision Mitigation System Problem, Road Departure Mitigation System Problem, & Auto High-Beam Problem) on the dashboard, along with the “BRAKE SYSTEM” light. After these messages and light popped up, the cruise control would not work. The crash mitigation system would not work (automatic breaking). The lane assist would not work as well. All of these safety features would not work which posed a combined severe safety issue to my family while driving the van, and those around me on the highway. After parking the van, I Googled these messages and saw that not only was this an issue with my model of Odyssey, but with several of Honda’s vehicles which use the same Monocular Camera. After getting my battery checked to ensure there was no low voltage issue (to which there was non and the battery checked out okay), I took the van to a Honda dealership. The Honda dealership performed a “Express Service Multi-Point Inspection” diagnostic test and told me on 12/23/2024 that the Monocular Camera was defective, which controls all of the safety systems listed above. On 01/02/2025, the Honda dealership replaced the defective Monocular Camera, to which they charged me full price for the Monocular Camera part itself and the labor to put the Monocular Camera in the Odyssey. Once the repair occurred, ALL of the messages and lights on the dashboard have cleared and all of the safety systems mentioned above are now working correctly.
Our vehicle is only a few years old and the front camera failed. It will not do any Automatic Emergency Braking, Forward Collision Warning, etc. Honda refuses to cover this even though it is a manufacturer defect.
On several occasions our honda van has slammed on the brakes without any vehicle or obstacle present. The automatic braking system has worked properly when someone ahead brakes aggressively ... but the instances i'm talking about have occur without vehicles in our lane. 1 time it was coming around a turn and i almost lost control of the steering since i wasn't expecting a hard brake. I haven't gotten it inspected or looked at. the safety feature seems to work properly but then will sense something that isn't there.
I went to park at a curb, and when I went to stop the van jumped over the curb and almost into a building. I had to almost push the brakes into the floorboard. It was like the car accelerated on its own. I was lucky there was only a flower bed it went through and nobody was on the sidewalk. I have called multiple Honda dealerships and they said there was no recall or any problems with the acceleration. No warnings went off, this was at 7 am when this happened.
