First problem was the check engine light came on. Called onstar and they said it had something to do with emission. Called dealer, they checked it out and said it was a faulty evap solenoid. Dealer replaced solenoid on 3-22-2012. While there, they also told me there was a recall on the drivers side airbag. I never received any notice about a recall. Said they fixed that too. Problem # 2- today 4-15, 2012, when I apply the brakes, its making what seems like a rubbing sound !! called onstar again, but they couldn't tell me anything. I will be taking this piece of crap car back to the dealers !! this car is only 4 months old with 2800 miles on it. !!.
