I was in touch with GMC, they want to say that I have to pay to get it checked by dealer and that due to the age of the vehicle... they don't want to do anything. Even though they know that there are recalls on this type of vehicle for years prior for the same problem. It sounded to me as if they were making excuses to not fix the problem.. I use to swear by Gm/Gmc......Now I just swear..... They know there's a problem..... Why not just fix it?
