The acceleration lags or stalls after braking to almost a complete stop. The lag is anywhere from 1 to maybe 3 seconds and I’ve almost gotten into multiple accidents as the vehicle has stopped in the middle of a lane or intersection when I’m trying to turn. The Honda dealership says they have been able to duplicate the issue, but said they don’t have a fix for the problem.

ADAS camera malfunction causing all driver assist functions to not work

Filed Apr 24, 2026 · Acceleration, Brakes · FL

My car has started breaking randomly without reason. Just a few days ago it slammed on the brakes. I was driving on the interstate and went around a bend, and my car slammed on the breaks. I. Talking from 70- 5mph in seconds. I didn't have time to do anything. Nothing in front of me, nothing on the side. The car behind me had to swerve into the median to avoid hitting me. My car almost caused an accident. Im honestly afraid to drive it. Im not sure if the radar system is an issue in other Hondas, but if i was in an accident it would have been my fault. If the person behind me wasn't paying attention my children could have been seriously injured or worse. Please look into this issue. Its more dangerous than the other recalls.

One week ago, I was driving on a highway, accelerating to the 65 MPH speed limit on that road, my van's accelerator completely stopped responding. Despite pumping the pedal repeatedly, I was unable to control my speed at all, and the car continued to lose speed. I had my three children in the car at the time, and given that people regularly go in excess of 70 MPH on that road, I was in danger of not being able to exit the road and/or being hit. I was able to coast off of onto an exit, and the car started responding at speeds of 30 MPH, but it was lurching and jerking while driving. We immediately had the vehicle inspected by an independent mechanic and have been advised that the transmission needs to be replaced. There were no warning lights for this failure. The car also had an incident about a year ago where all lights came on and it stopped responding. At that time, we had Honda dealership examine it, and they said they could not find any issues. Additionally, the car has been jerking slightly while shifting, but the issue improved when we had the transmission fluid flushed at the Honda dealership again about a month ago, and no issues were noted by them at that time. We have performed regular maintenance and safety inspections on this vehicle.

Issue Description: My 2018 Honda Odyssey (VIN: [XXX] ) has a total failure of the Multipurpose Camera, permanently disabling the Collision Mitigation Braking System (CMBS), Forward Collision Warning (FCW), and Lane Keeping Assist (LKAS). In addition to these, the regular Cruise Control is also disabled. These are primary safety systems, not elective conveniences. Persistent Failure: Errors occur immediately upon every startup. Mid-Drive Danger: Systems have deactivated multiple times while in motion, causing sudden, unpredictable loss of driver-assist features at highway speeds. Total Loss of Control: Both Adaptive and Standard Cruise Control are completely disabled, forcing manual-only operation. Infrastructure Failure: The failure prevents the vehicle from recognizing lane markings (RDM/LKAS), leaving the car unable to assist in steering corrections. Safety Risk: The vehicle can no longer perform emergency braking or provide collision alerts, significantly increasing the risk of high-speed crashes. This is a premature failure of a non-wear safety electronic at 91k miles. It is a severe safety defect that leaves the vehicle unequipped with the crash-prevention technology it was designed to have. Manufacturer Response: American Honda (Case #16167889) and NCDS (Case #XXX) denied assistance, citing the expired 3yr/36k warranty. I contend this is an extension of the known electrical architecture defects in this model year (e.g., Recall 23V‑431), and a component intended for the life of the vehicle should not fail such that it disables multiple safety systems simultaneously.

Camera projector fail and 6 warning ⚠️ lights came on, very common issue.

My vehicle stalls when I turn left or right from a stop light or sign. It’s incredibly dangerous especially when I have my kids in the van with me. We’ve taken it to the Honda dealer for repair and they’ve done work but the issue has not been resolved. I’ve seen countless forums of people with this year make and model who have had the same issue. I don’t know why there’s been no recall but someone is going to get seriously hurt if this issue is not resolved.
