I took my car in for warranty work, no problems with the service. Bad window motor, driver's side, and regulator. Caused the window to lock all the way up and crooked. Have to order the part. Tech said vibration caused two of the regulator bolts to come loose, suggested they weren't tightened properly from the factory.
This is the second warranty service, second for this door and window. First, it was squeaking, and they lubed the seals. Now this. Just something to keep in mind in case your window starts squealing.
