2020 Audi Q8

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 it, the window would reverse and lower again. I was eventually able to close the window only by repeatedly operating the switch in very small increments until the glass finally reached the fully closed and sealed position. I have previously cleaned the window and window-channel area and attempted to resolve the problem, but the condition continues to return. Because the window can unexpectedly lower and can become extremely difficult or impossible to close normally, I am concerned about the reliability and safety of the window regulator, anti-pinch system, door control module, or related software/electrical components. This has been an intermittent problem for several years and is not normal wear or a one-time occurrence. I am reporting it so NHTSA can determine whether other owners of 2020 Audi Q8 vehicles are experiencing similar front-window failures and whether further investigation is warranted.
