The MMI ( main screen) system randomly reboots every 5 minutes, even when using CarPlay, which is unsafe. Please check it out. Thank you!Owner report · Electrical System · Feb 2026
I turned on my car and several malfunctions came on the dash,and would not start and went in limp mode. A local mechanic stated it's the electrical component of the coolant pump causing malfunction. He also stated that could lead the car catching fire if overheats since the 5V is dipping below due to the faulty coolant /water pump. Ultimately forcing the car in limp mode for safety precautions. The problem is I purchase my car at 87,000 miles from the Audi dealership, and the extended warranty that covers the car is 80,000 milesOwner report · Electrical System · Feb 2026
The vehicle has 36000 miles on it and the oil cooler has failed. The car is meticulously maintained. This failure compromises the ability for the engine to cool properly. Because of the failure, coolant is then forced into the engine oil potentially destroying the engine. Engine replacements are 10,000 for these types of cars. Audi is aware of this issue and should repair all vehicles with this known issueOwner report · Engine · Jul 2025

I was driving along the express way when I heard a loud explosion, I look up to see my sunroof exploded and there was glass all over the kids and I. The explosion was so loud I lost control of the car and almost veered off the road. It was terrifying. It happened last year in the winter then happened this year as well. The temperature outside was about 30degrees, and I was driving about 70mph. There were no other cars in front of me at the time. My daughter and I had scratches from the glass on our backOwner report · Structure · Jan 2025
