"Driver's side window became inoperable 5 days after I bought the car. Have appointment to go to Audi Service - but haven't yet."
Anonymous, CA (2021 Audi A5 2.0T 2.0-L 4 Cyl turbo)"The windows are frameless, so each time you open a door the window automatically opens a tiny bit then closes after you shut the door - I suppose to prevent cracking the glass? This causes the window motor to wear out more quickly, and on mine the cable that rolls up the drivers window snapped while driving causing it to open slightly and not roll up or down. When I called the dealer they knew immediately what I was describing as if theyd dealt with it regularly, and the service manager even said one of the costs of driving a cool car. Form over function for sure."

"One month after purchasing my car, I found a plastic undercarriage guard piece hanging slightly from the bottom of the vehicle, so I popped it back in to place. I had to continue doing so about every 2-3 weeks, but after about the fifth time I just pulled the whole thing off. When I searched the issue online to see if removing it might cause issues, one Reddit user said the first thing Audi owners should do is throw the piece in the dumpster. The comment had around 100 upvotes, so Id venture to say its a common problem."
