In owners' own words
Shortly after purchasing in 2025 I began having occasional issues with the door locks. Eventually the issue would self resolve but now I have experienced at least 2 times in last month being locked inside the vehicle and unable to exit without climbing into the passenger seat. I have not taken it in for repairs yet due to cost concerns but I am worried about this dangerous situation. Electrical system
The electrical system failed while driving at highway speeds on the interstate. Car lost power, all safety systems shutdown and I had to navigate the car while coasting off the road. Car would no longer start and left me stranded on the side of the interstate for 2hrs. I have since learned from the audi service department that the 48V generator had failed and caused this situation. Electrical system
First sign of the vehicle is shaking and making noise while driving over 65mph. A few days later, the tire pressure warning was on. The next day, electric system malfunction light was on, advising me to contact service center. At the same day, steering function light was on and it was stiff to drive the vehicle. A few miles down the road, engine shuts off, and was unable to restart. Electrical system
