After a rainstorm or contact with water on the outside of the vehicle, the vehicle's roof leaks tremendously, near front sunroof and windshield column on passenger side, and around the rear sunroof. This problem has been fixed over 3 times by a GM dealer under warranty, but now the car is not under warranty and I will be paying for the repairs, and the repairs don't really repair the problem. My vehicle's interior and ac now smells like mold/mildew, and I am greatly concerned for the healthy of myself and my family.

The car has had electrical and engine problems since we purchased it due to water leaks from a flawed sunroof design. Even after a recall to fix the sunroof to prevent water leaks; it continues to leak and damage electrical and engine systems. This is an ongoing problem and is a widespread concern for the 2007-2008 GMC Acadias. I would like someone to investigate this problem. I believe it is a safety concern because the leaks occur in the area where there are airbags. I think there is a structural defect that may not be able to be repaired and it presents a safety hazard for all who drive these vehicles. Please investigate this problem. Do not let GMC sweep this under the rug!

Sunroof leaks in to electric system, thank god driving on side street, brakes locked up and was able to get to side of road. Dealer westboro GMC tried to fix leak X 4 but leak continues, brake stability problem, remote start, mold, car pulls to right when brakes applied, just to name a few of the electric problems caused by water running in to electric system. Dealer washed there hands of it. I now own a $40,000 lemon.
