I am reporting a recurring problem with the front passenger-side window on my 2020 Audi Q8. This issue began when the vehicle was approximately two years old and has continued intermittently. When attempting to close the front passenger window, the window will sometimes automatically reverse direction and go back down instead of closing. On September 7, 2026, after the vehicle was parked and turned off, the passenger window lowered and would not close normally. Each time I attempted to raise…

I own a 2019 Audi Q8 3.0 TFSI that has been regularly maintained and serviced through authorized Audi dealerships. The abnormal engine ticking/knocking did not suddenly begin at 91,000 miles. A similar noise could be heard earlier, but it was not identified by Audi service as an internal engine/piston problem. Because the vehicle continued to be serviced by Audi, I believed the sound was related to the fuel injectors or normal engine operation. At approximately 91,000 miles, the noise became…

I am reporting an ongoing cooling-system/water-pump issue with my 2020 Audi Q8, approximately 75,000 miles. The problem began when the vehicle repeatedly displayed a low-coolant warning. Inspection confirmed the coolant level was very low and a significant problem involving the coolant pump/vacuum system was diagnosed. The water pump was subsequently replaced. After the repair, the vehicle initially appeared normal, but problems continued. I experienced engine sputtering/rough running and the…

At approximately 52,000 miles, on August 11,2026 (or earlier), my vehicle developed a coolant leak that was traced to a failed coolant shut off valve. The coolant shut-off valve failure allowed coolant to migrate into the vacuum harness, vacuum reservoir which contaminated the water pump. This resulted in the vacuum system becoming filled with coolant, compromising components that rely on vacuum pressure to function correctly. The combination of these failures — water pump contamination,…

While traveling on a major freeway between 65mph and 70mph, vehicle alarms started sounding and numerous alarm / warning messages appeared on the dashboard display, while at the same time, the automatic door opening mechanism (e-latch system) unlatched and partially opened the driver’s side door. The partial opening of the door at high speed is hazardous, and could also cause a major distraction, resulting in a crash and/or danger to others in the vehicle and/or on the highway. The vehicle is…

On [XXX] about [XXX], I was driving my 2024 Audi Q8 e-tron Premium Plus (VIN [XXX]) in a private parking garage while on the clock for work. I had just left a work meeting and was traveling back to my office. I was backing out of a parking space next to a concrete column when my passenger-side mirror contacted the column. The vehicle’s proximity sensors beeped, which appeared normal. I then pulled forward slowly to straighten the vehicle and assess the mirror. My foot was initially on the…

The last time I left the car to the dealership to have a recall serviced - it did this. I let the Audi (Fred Lavery Birmingham Michigan) know. They did not respond / did nothing. It has happens at least 10x at varying speeds (some high, med and low speed) since the day I left the dealership
