Vehicle has a sunroof drainage issue. Water leaks in through the corners of the sunroof and spills into the dashboard and under the carpeting. The vehicle has suffered electrical damage, corrosion, and mold because of the sunroof drainage issue. I have seen forums with hundreds of other owners who have suffered the same exact sunroof drainage problem with their 2007-2008 GMC Acadias. GMC says my vehicle is not listed in the recall, but I find that laughable. There are way too many Acadia owners that have this exact issue for it not to be a problem with all Acadias.

This car has leaked since the day I bought it. I have taken it to the dealership I bought it from multiple times. The last time they looked at it they told me that there was a leak but they could not find where it was. My amp has shorted out due to all the water and I can imagine what's next. I am so scared to drive my car because of what could go out next. I wish gmc would do something about all of our issues with the same water leak! I am getting pretty tired of getting rained on inside my car.

My 2008 gmc acadia leaks water in several different locations inside the vehicle when it rains. It has leaked water through the air bags and I'm now concerned that the air bags could be water damaged and compromised. It leaks through electrical components. It smells like mold and mildew in the car. Condensation builds up in the car frequently after it rains. The car will also sputter and act like it is going to stall out while driving on the highway sometimes. It tells me to 'service traction controls' and 'service stabilitrack'.
The sunroof drainage tubes get clogged and leaked water which caused the fuse box in the dash to be filled with water. Also flooding all the floors and the battery compartment inside the car. Which in return causes the car to not shut off when you turn the key off and take it out. It also causes all kinds of sensors and check engine lights to come on on the dash like service airbag service stable track causes the traction control to turn off falsely tells you that engine oil needs changed also causes the battery to go dead for no reason also displays AC off engine hot
