Complaint Timeline
Chronological view of owner reports
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 miles
The MMI ( main screen) system randomly reboots every 5 minutes, even when using CarPlay, which is unsafe. Please check it out. Thank you!
