Tl- the contact owns a 2009 GMC Acadia. The contact stated that while operating the vehicle the check engine light would illuminate and the vehicle would suddenly loose acceleration and sputter.

First problem was the timing chains needing to be replaced at 18000 miles. After that repair was made the gas mileage was averaging 11 mpg. It was a one year old car! after that, it was a multitude of problems. Steering rack/power steering replaced and 'fixed', electric stabilitrak lights going on and off, dvd player not playing properly. All things the dealer had said they fixed (after they whispered that I should not have bought an american car. ) now the transmission is acting up. Rolling down an incline when I was trying to back out of a parking spot. The dealer told me it was fine and they could not duplicate the issues I was having. I've written two letters to gm corporate to complain about the sub-standard vehicle. They were helpless and will not assist in any replacement of the car. They even told me that this would be a difficult car to trade in considering the problems I have had with it. Who is kidding who? I would never recommend this car and hate to continually put my family in itã‚â¦. It is unsafe. Period.
