Example complaints
Electrical system: “Audi A6s have had massive issues with the door actuators. There are times when you go open the passenger side doors (both front and rear) and the doors will not open as there is either an electrical, software, or device specific issue. It requires 2-3 pulls of the door latch to open the front and rear passenger doors. The issues keep appearing a month or two after the dealership supposedly fixes the issue. I have had this fixed/reviewed 4+ times between Freehold, NJ and Cherry Hill, NJ Audi dealerships. This has been going on since I purchased the car in early 2021. …”
NHTSA complaint #11722663, filed 2026-03Forward collision avoidance: “The automated emergency braking randomly kicks in.. This has happened two times in the past 3 months. Nothing was around to cause the aeb to activate. This could have caused a serious accident if someone was driving behind me at the time. It jolted passengers in the car. The car came to a complete stop and nothing in the vicinity, no oncoming traffic, no pedestrians, no animals....”
NHTSA complaint #11398232, filed 2021-02, 6,000 milesOther or unknown: “I was traveling at ~65mph on the freeway when the sunroof spontaneously exploded. It was louder than a gunshot—I nearly lost control of the vehicle. The explosion occurred in the outward direction. There was no evidence of impact of preexisting damage. Internet research suggests this is not an uncommon occurrence.”
NHTSA complaint #11698392, filed 2025-11Body and structure: “This issue has been happening since I got the car and is getting worse by the day. The car only has about 11,000 miles and I bought it when it had almost 10,000 miles. Something in the dashboard and behind the instrument panels (A/C Controls and User Screens) makes a lot of Vibration Noises/Sounds as the car is slowly accelerated or as we drive over some uneven road. It seems like there is something loose. And this is getting worse by the day. When you pay a top price for a luxury car like Audi you expect that the care is built solid and not with cheap parts... …”
