“My CMBS, ACC, LKAS and Road Departure Mitigation System all light up on my dashboard as well brake system light. I had a alignment done on my car about 2 weeks ago and the next day they came on. I went back to the shop where I had the alignment done to ask why they came on. They check the alignment again and said something about calibrating the sensors and checked that again. But the lights didn't go off.”
NHTSA complaint #11612459, filed 2024-09“I got 5 lights on my dash stating that I have an auto high beam problem, road departure mitigation system problem, collision mitigation system problem, lane keeping assist problem, and adaptive cruise control problem. I got these lights on my dash at the exact same time and this happened 1 week after my car alarm started going off randomly. I will now have to change my windshield camera sensor. Seems like this is an issue with many Acura owners.”

NHTSA complaint #11766197, filed 2026-09“I was rolling up to a stop light at approximately 20 mph when the frontal crash mitigation feature suddenly slammed the brakes on fully to a complete stop. I searched the web and found that there are other owners of this model that have had similar occurrences. I could easily have been rear-ended if someone had been following. I was lucky that didn’t happen. Since that day, I have been afraid to drive the car until I have disabled the feature.So every time I start my car I have to disable this mode. There is no known fix. No technical service bulletins etc. regarding this problem. …”
