Various gm vehicles have a known defect that allows water from the sun roof drain to enter the passenger compartment and more importantly allows water to enter the passenger compartment fuse block. This defect is covered under service bulletin #08-08-57-003c. This vehicle has had numerous electrical system issues that only occur during heavy rains and the dealer has been unable to recreate the problem after things have dried out so to speak. Most recently after a heavy rain, the battery was dead and when replaced with a new battery, the engine would not shut off even after the key was removed. This is a serious safety concern that can result in injury or death. The only way to shut off the engine is to remove the ecm fuse from the under hood fuse block. Not being able to shut the engine off via the key can have serious life consequences in the event of an emergency. This is a wide spread issue that seems to get worse over time and ends up with not being able to shut the engine off. The gm models affected by the service bulletin as follows: 2008-2012 Buick enclave 2007-2012 GMC Acadia 2007-2010 Saturn outlook.
The battery has died three different times after being driven the night prior. I have taken it into the shop once where they said nothing was wrong, but the battery was low, they charged it. The second time (a week later) I was told the battery could not keep a charge so they gave me a new one. Now three months later, it dies again. Waiting to hear what they are going to do now. I can't imagine a car that is a year old can go through two batteries, needing a third.
