2020 Audi Q3 Electrical System

Rear hatch randomly operable / inoperable. "Reset" computer without success. Dangerous situation as anything inside hatch is not not accessible. Was told by Audi that the entire rear hatch latch system needs replacement and this is "a common issue"...

I purchased a 2020 Audi Q3 S-Line (VIN: [XXX] ) on [XXX], with 27,564 miles on it. I bought the vehicle from a dealership that specializes in high-end aftermarket cars, and they provided a maintenance report stating the vehicle had passed all inspections at the time of sale. The vehicle had been imported from Canada to the U.S., and the Carfax report reflected consistent maintenance at authorized Audi dealerships in Canada, including a full inspection and alternator/electrical system check roughly a year before my purchase — with no problems reported. In early July 2025, I began experiencing issues with the MMI system: •A loud, persistent humming sound when using Bluetooth or the radio •Audio glitches and failed system reboots •No dashboard warnings or battery alerts After researching, I suspected a low-voltage or charging issue. I took the car to an auto parts store for diagnostics, and at 28,932 miles, they found the battery was severely depleted and the alternator had failed completely — it was no longer charging the system. This means the alternator failed only 1,368 miles after purchase, which is highly abnormal for a well-maintained, low-mileage luxury vehicle. Alternators typically last 80,000 to 150,000 miles. Audi has acknowledged similar issues in Q5 and A4 models, but nothing yet on the Q3. While I know the vehicle is out of warranty and was not purchased from an Audi dealership, I am requesting: 1.That this issue be formally documented and investigated for possible recall or defect pattern. 2.That Audi consider a goodwill repair, based on mileage, maintenance history, and how soon the failure occurred after passing inspection. 3.That this be flagged specifically for Q3s imported from Canada, as mine was. This failure could have left me stranded with no warning. I’m reporting it not only for my own case, but to potentially help others who may be silently experiencing the same issue.

THE PANEL NEAR THE SUNROOF CONTROL BUTTONS AND LIGHTS HAS A LEAK. IT LEAKS WATER EVERYTIME IT RAINS OR DURING A CAR WASH. MY SAFETY AND OTHER SAFETY ARE PUT AT RISK BECAUSE THIS WATER LEAK IS COMING OUT OF MY LIGHTS AND OTHER ELECTRICAL CORDS FROM ABOVE. THIS IS A POTENTIAL FIRE HAZARD. THIS PROBLEM HAS BEEN REPORTED BY OTHERS BUT NO RECALL HAS FORMED FOR THIS MAJOR ISSUE. THERE ARE NO WARNINGS OR MESSAGES APPEAR FOR A WARNING, IT JUST OCCURS.

While waiting at a signal, i got at message that my maps could not continue because I had no power, then the park assist came on with no explanation. After that, I got the message to put the car in park to prevent it rolling away. I tried to restart, but it would not. As the signal changed and traffic had to move around me, I put on the emergency lights and continued to try to start the car. It took 3-4 tries. I then took it to the dealer who did an inspection and test drive, but nothing showed up. I was about to get on the freeway when this happened and worried about driving. Even after inspection of the vehicle, i am hesitant about driving on the freeway and worried about this happening again, this time with the engine in gear.
