Water leaking in into passenger area and on instrument panel body electrical centre causing fuse block to become wet and short out. All dash display went out and came back on with the "service air bag "service tire maintenance system" illuminated. Purchased car on 7/16/08 and leaking occurred approx 1 month later on 8/18/08. Have had to take car back to dealer several times. It has been at dealer 2 of the 6 weeks I have owned it. I am concerned that air bag will deploy. Have contacted GMC and they are very un-helpful.
