I had bought the car brand new sometime in Aug 2012. The car has about maybe 600 or less. I have taken the car back to the dealership about it on more the one occasion and to this day they cannot fix it but have put some new front end parts which seem to help a little and has since come back with the same problem if not worse. And car now has about 8500 miles on it. The service manger called there Tech line and says they have no fix. They know its not just my car but the loaner cars they gave me ( same car ) has the same problem. I will be taking the car in to another Buick dealership to see if they have a clue.
