A word of advice. IF your car is under warranty and you have an issue....Get it documented ASAP or sooner. Even if they dont do anything for you. You want a paper trail of your issues for down the road. When your done reading this go to your dealer with the issue. And go back every few weeks. Keep bugging them for a repair. You bought a brand new car not a old mr2 with a worn syncro. Yea. It wasnt a ton of money in the grand scheme of a brand new car purchase. But it should still be a brand new car. GM is the cheapest car maker there is ever since the bail out. They use cheap parts and labor and just want to crank cars out without care of quality. So get everything documented and pursue a lemon law case if it comes to that.
