Graff Chevrolet Okemos

We have a 2007 Trailblazer. The car seems to think we are on a curve in a skid condition. It applies the brakes while we are driving...wet or dry pavement...cruise on or off...it doesn't matter. Imagine driving on the highway and your car brakes itself. The brake lights do not come on so the driver behind you (probably on your bumper) has no idea what is happening. Sometimes the two Stabiltrk warning lights come on but the brakes do not. Surprise! Surprise! Are the brakes going to be applied any minute or is it just joking? Neither the dealer, the service department nor GM care. They are guessing it "might" be a computer glitch. So they are going to test new software which might be available in a few weeks. Maybe that is the problem...maybe it isn't. In the meantime, we are forced to drive this car. They would consider ending the lease if we give them $9000 to make up the difference in the value of the car because they can't sell the stupid things anymore. After trying endlessly to solve the problem, Matt from the service department, called us to come get our car "right now" before they close or they will charge us $50 a day for their loaner which had almost no gas in it when they gave it to us. Greg in sales told us we could keep the car until the next day so we could drive our neighbor to Grand Rapids the next day. Not so with "King Matt." When I tried to talk to him during that phone call he told me to be quiet. Nice. Good way to treat a customer. Great for good will and a great reputation. We wil never, never own another GM product. As long as we are forced to drive this potential death trap, we will be taking it for service to another dealer. I would definitely warn everyone I know to stay away from Graff Chevrolet. Unless, of course, you really like to be abused and disrespected.
