I have a 2011 Buick Regal Turbo that I regret purchasing because of frequent rattles throughout the vehicle. I called the GM customer service number and was put in touch with a district rep. Each time a new rattle develops, the rep tells me to take it back to the dealership. I bought a new vehicle so that I wouldn't have to waste my time running back and forth to the service dept. My car was back at the dealership today for the loudest/most annoying rattle. It started rattling again on the way home. Other than returning to the dealership on a regular basis, what can I do to make this right? Thanks!
