Took car to dealer, called GM neither wanted to deal with it. It is a defect. The bow on the top needs to be adjusted so the window does not rub the top when doors are opened. The trim is fraying. There is a service bulletin about this and GM did not tell me. GM says the car is too old, 8yrs old but 7100 miles. The car is a piece of junk. The body parts are misaligned, the top is misaligned. Brought this to their attention years ago and they told me that there is a percentage of allowable flaws and defects. I am ready to get rid of the car and I do not recommend any GM product to anyone. The consumer is a small fish to them and more where we came from. A few less buyers is no skin off of their back. If they would spend less on ads and more on their products and customer satisfaction their cars would be worthy of my consideration.
