This event happens intermittently, and has occurred approximately 4 times. When the issue occurs it happens as follows: 1. Vehicle comes to a complete stop, and driver's foot has depressed brake pedal 2. Vehicle automatic start/stop feature turns off engine. 3. Driver lifts foot off pedal, begins to apply pressure to gas pedal. 4. Vehicle automatically re-starts engine 5. Vehicle starts to move forward, and then lurches - it feels like the brakes are being applied by the vehicle independently from the driver's action. 6. Alerts start appearing on the dashboard - a message that the Forward Collision Warning System has been disabled and the "BRAKE" light starts flashing for 30 seconds to a minute afterwards. 7. Vehicle then starts to move forward without issue, Collision System message goes away, but BRAKE light on instrument cluster continues to flash for a period of time. …
The contact owns a 2020 Honda Odyssey. The contact stated that the Traction Control, Adaptive Cruise Control, Lane Keeping Assist System, and Road Departure Mitigation warning lights illuminated. The vehicle was taken to a dealer, where the cause of the failure could not be determined. The contact continued to drive the vehicle as it passed state inspection. While driving approximately 65-70 MPH, the cruise control suddenly failed, requiring the contact to manually steer the vehicle. Additionally, the Collision Mitigation Braking System, battery, and ABS warning lights illuminated. The contact stated that the ABS light illuminated after the brake pads were recently replaced, and the ADAS calibration was not performed. …
Car was operating fine on the way to a game on 11/25/2024. Parked and went inside to watch game. After the game I went to my car and when I cranked it all the warnings below came on. **Auto High Beam problem * problem **Brake System problem **LKAS problem those are the warnings I can remember. I immediately cut the car off and walked around to see if maybe I had been hit while parked cause something told me it could be a camera issue with the LKAS problem . I had not been hit. The car was fine and just as it was when I parked it. I cranked it again and the lights were still on showing problems and stayed on. I took it to the dealership and they said it's the multi-purpose camera malfunction/went out and needs new one.
While parking and approaching another car in a parking lot, the van automatic braking system randomly started blinking and the brakes automatically applied, pulsating and grinding loudly for several seconds for no reason. I believe my safety and my passengers safety was at risk. The problem was random and not reproduced since it happened. The vehicle was not inspected. No warning lamps or symptoms appeared prior to this occurring and have not occurred since. It was a scary experience, I assumed it was some kind of electronic glitch.
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.
While driving down the interstate the van went in Neutral and a message appeared on the screen that it was in Neutral, pull over when it is safe. The lights on the dash dimmed and no other message or warnings appeared. As I pulled off the interstate I was unable to use the brakes. We tried to put the van back in Drive but was not successful. We were able to get the vehicle in park and come to a stop. I turned it off and back on. No other messages appeared. The vehicle drove as expected and brakes worked.
Multi-Purpose camera has failed according to Honda dealership. No safety features work in the car. You pay for the car to have these features and then they fail after only 3 years? Have been dealing with this issue for almost 2 years now. Honda wants $1,800 for the new camera. This is a safety issue that Honda should be responsible for fixing. No adaptive cruise control, no lane keeping assist, no auto headlights, no collision mitigation, no blind spot alarms.
This is the second time I've had to bring my car in. I have a variety of different warning signs popping up and I see that I'm not the only person that this is happened to when I look at Reddit online the malfunction is somewhere within the car system and it's because of a windshield camera, which has nothing to do with the, warning signs that I am getting on my car. This needs to be recalled and fixed for free.
Multiple warning lights, all for the safety system: ACC, automatic emergency braking, etc. I am told by the dealer that this is due to a faulty forward camera. Looking at the NHTSA site and other forums, this is a VERY common issue and should be addressed.
