General Motors horrible response to warranty concerns

[Boar-Ral]

I am so upset after dealing with General Motors on the telephone that I am still shaking. The problem stems from the rear body seals on my vehicle. These seals bridge the gap between the rear bumper and the body. Unfortunately, they are in so tight that they actually rub against the body, right through the paint and primer, down to bare steel. They repaired it last year as part of a "good will" deal but left the seals intact. Now, they have worn through the paint again and General Motors refuses to repair it, citing that the seals are not defective.

I am at wit's end. I own a vehicle that is not even three years old and now, the paint is beginning to peel back, slowly working up the side of the vehicle. Does anyone have any suggestions or recommendations? There are not many Hummer dealerships in Canada, so I do not have the option of driving to another one in order to get a second opinion. (I have been dealing with my local dealership, and when they scoffed at my claim, that is when I spoke to General Motors directly.)

Please, any advice would be appreciated.
