Took my 2008 Malibu to the service department to figure out why water was pooling on my rear passenger floorboard. Had done some research online myself and found that Chevy Malibu's have had problems with the a/c lines getting clogged. Dropped my car off on a Tuesday morning, did not receive a call from the dealership the whole day about what the problem was. I called the service department Wednesday morning and was told my car would be ready to pick up in about an hour, they needed to put my seats back in. WHAT??? Mack told me at that time that it was a clogged a/c drain, they had fixed it and pulled up my carpets to clean water. I inquired at that time about the cost (since they didn't even communicate to me what the problem was) and I was told the invoice was not ready, but they would "shoot me straight" RIGHT!!! $294.00 later my a/c drain is unclogged and my carpets cleaned and treated with Lysol. Are you kidding me??? Whatever happened to speaking with customers and communicating cost before repairing a vehicle??? Treating with Lysol??? I could have done that for a hell of alot less. $256.89 of my bill was labor, yet no labor hours were listed. Very unhappy with this dealership and very unhappy with Chevrolet's customer service department. My grandfather is a retired GM employee and he would be rolling over in his grave right now. Have owned many Chevy vehicles and I will think twice about EVER purchasing another one!
