We have a 2007 Acadia that we purchased in March of this year. It has about 80K miles on it. The first problem I had was a Freon leak. In fact, it was empty and I had to take it in to a service department to have it filled. Dealership didn't offer much assistance. Then the check engine (orange light) started coming on. It tends to come on when I have been driving for a while and have had to sit in idle for a while. Once it comes on pressing the gas seems to rev up the engine more. This is an on and off again problem. Now I am getting the stabilitrac message followed by a check brake system message. I wasn't offered any type of extended warranty at the time of purchase on this vehicle. Now I'm starting to wonder if the dealership did that on purpose because of all of these issues. Anything I can do other then eat all these costs??? So far I'm a little disappointed with GMC.
