I was involved in an accident with with my family. Pregnant wife and daughter. I got into a front end collision and I was at fault. The forward collision warning didn't activate, Neither did the automatic emergency braking. This system has never failed on me and car has always stopped every time..
The automatic braking system beeped alert then applied brakes when I was going around a sharp curve, with cars behind me. Luckily they were far enough behind that they didn't hit me. This has been happening since I first got my Odyssey. I asked the Honda dealer about it if it was a defect and they said no that's how it work. I asked if I could turn it off permanently and they said no - I had to turn if off each time I turned on the car. Which I do most times but I forgot yesterday. I started turning it off regularly when it slammed on the brakes going around a curve some time ago bringing me to almost complete stop with car behind me. I probably should have reported earlier. I was in the car with a friend yesterday when it happened and she has a different model Honda and says it happens to her as well. …
On 7/28/26, my 2018 Honda Odyssey began displaying the following warning lights and system messages on the dash: Adaptive Cruise Control (ACC) system error Lane Keeping Assist System (LKAS) error Auto High Beam system error Collision Mitigation Braking System / forward collision error These errors were present before I replaced the 12V battery. I had the battery tested at that time and it failed a load test, so I replaced it, expecting the ADAS-related errors to resolve. After the battery replacement, the original errors remained, and additional warning lights appeared, including a transmission system problem indicator and a brake system warning light. I disconnected the negative battery terminal for approximately 10 minutes in an attempt to reset the modules, then reconnected it. …
Prior to purchasing this vehicle, On the test drive, the vehicle slammed on the brakes for no good reason. The dealer assured me the collision mitigation braking system ("CMBS") can be turned off, so I bought the car. I then learned that the CMBS automatically turns on every time the engine is turned on. I must shut CMBS off each and every time I start the car, but since my other car is a Tesla (which doesn't have this problem), sometimes I do forget to shut off CMBS. Through out my almost 7 years of ownership, the car has slammed on the brakes COUNTLESS numbers of times for absolutely no reason at all. Sometimes no cars are behind me, but there have been several times when cars behind me have almost crashed into me due to my faulty CMBS. …
While driving on a clear road, with or without heavy traffic, the collision mitigation warning shows up on the dashboard display. Sometimes the warning for the collision system goes off and the system tries to brake and jerk the wheel. If I have the wheel firmly I can correct it and it resolves. It can happen on a clear road with no one around or in heavy traffic. Yesterday it happened in a single lane with barriers on both sides, a road around Logan Airport in Boston, with no vehicles ahead of me. The car tried to steer me into the barrier. I was doing less than 25 MPH. The warning had been going off for a while but now that the steering and braking are involved it's much more serious. I reported it to the dealer. They said they did a system check and couldn't find a fault. The braking and steering problem first occurred about a month ago. …
My Odyssey randomly began displaying all of the ADAS warning messages: The Brake System indicator light comes on, Forward Collision Warning, Lane Departure Warning, Lane-Keeping Assist, Auto High Beam System error, etc. These came on beginning 7/25/26 and have come on everyday since causing the entire ADAS system to be inoperable. There have been a few days that they didn't come on immediately. I have had a few days where they came on half-way through my drive. This is a safety issue due to a defect in either the front camera or wiring to it, a nuisance, and something Honda needs to correct. It seems to be way too common of an issue according to my research. There hasn't been any damage to the van and no reason for these to come on. I have done research and see this has happened to many people. The replacement camera is costly as well as the calibration. …
See service Honda Service Bulletin 20-100 Dated 2-11-2021.The fuel Injectors part Number 16010 (6EA) has failed and my dashboard display , displays most of the sensors that means there is an actual problem, or a false reading. As a Honda owner, I cannot determine if it is an actual fault or a false reading. I had Rusty Wallace Honda dealer check the car using OBD device and the equipment indicates a code 219A, which indicates bad fuel injectors. Now after the check additional and different sensors are displayed with problems than were displayed prior to this check. The trouble shooting and after displaying the code 219A indicated a catastrophic failure. Rusty Wallace has verbalized the results and that I should continue driving the vehicle, that this would not damage the engine or the car. …
