Windshield wipers banged against edge of window since I first bought the car at Koons. For the last two years, "adjustments were made" each time I brought the car in for service, and each time the problem was not resolved. I am still waiting for the dealer to fix it. How difficult should this be? Even with the premium warranty I purchased, very little was done each time. Now the dealer is thinking about replacing the motor for the wipers. After two years of problems -- it's about time, and we'll see if it happens.
