“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 #11691417, filed 2025-10“I am getting a U129D-00 code, my vehicle isn't passing 50mph. Says lane keep assist problem, vehicle stability problem, precision steering problem, i am experiencing all the characteristics of specific service bulletin 15-050. What are my options”
NHTSA complaint #11674122, filed 2025-07“I was driving and a lot of warning lights came on, on the dash and 10 different warning messages in the message center. The alignment instantly messed up jerking my car to the right and I had to try to gain control and correct. Luckily, I was only going about 25-30mph and was able to correct. If this would have occurred moving faster the outcome could have been very different. Dealership is stating it is the P-AWS actuator on my 2018 Acura TLX that have gone out and caused this to occur. …”
NHTSA complaint #11520637, filed 2023-05“In September 2023 went in for an oil change. Next day all My CMBS, ACC, LKAS and Road Departure Mitigation System all light up on my dashboard as well brake system light. I called and took the car in they said that it had something to do with the camera sensor. I left a complaint and the manager called after I explained to him he said he would call me back. 1.5 years later he never called back. In October 2024 my car alarm started going off for no reason. I took it in and $1000 to fix. Seems like a lot of electric issues with this car”
