Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“My cruise control, automatic lane changing indicator light indicator, brake indicator light, high beam light indicator lights all keep coming off and on. Researching it on YouTube states that it’s the camera on my windshield getting too hot and it’s a known issue. It’s $1800 To fix but others have stated they get fixed and it doesn’t resolve the problem. Asking for your help.”
NHTSA complaint #11741032, filed 2026-05“My car was stopped at a light with idle auto on. The car shut off and switched into neutral with check engines lights on the dash. I was not able to switch the car to drive. I had to restart the car. This has happened twice in 2 weeks at busy intersections. I have brought the car to the dealership but they are unable to replicate. There was no prior warning lamps or signs prior to this happening.”
NHTSA complaint #11473786, filed 2022-07“The vehicle stalled and was unable to start again, Called AAA , they jump started but when I went to dealership they said it wasn't the battery. The car electrical electric system was flashing. The breaks won't release. This is not the first time. My car is currently in Acura service for 5 days and they can't figure out what the problem is. My friends car also has had similar issues. I have a video of the flashing indicators. The car has only 33k miles.”
NHTSA complaint #11627160, filed 2024-11“Multiple errors Lane departure and advanced driver support, ACC LKAS, auto high beam, and braking system. Looking into this more i see lots of people with the same issue failing front facing camera and not a cheap fix. Is there any current investigations into this problem or a software upgrade? I clear the errors and they come back once car is turned off and back on. If no fix to the current system there should be a way to disable LKAS and ACC without spending $2000 to replace the system.”
NHTSA complaint #11759085, filed 2026-08“I was on a bridge heading into a tunnel stopped due to traffic and the car shut off completely. The screen said to put the car in park and restart it. I tried several times and after a few attempts it started back up. This is the third time this happened. I had a recall when I purchased it and had the recall addressed for the same issue. Now I am back at Acura again. And being told I may have to pay for diagnostics. The car is still under warranty.”
