I guess I am one of the lucky ones. I didnt have a problem with marker light noise until about 800 miles or so. Then the windshield rattled like crazy, very embarassing when taking friends for a ride in the new "toy". Anyway, called the dealer, set an appointment and I was out the door in 45 minutes. They even test drove it to ensure no more noise. Now I am very pleased with my Hummer and the dealership's service.
