Depends on how good your dealer is. You run a very high risk of having more problems when you get the car back. There are a number of horror stories in this forum. I don't trust mine.

On a side note, I still have not figured out what sounds like a piece of plastic bouncing around in my car. It wasn't there before (for the last year) and just started. I thought it was my sunglasses because I moved them and the sound was gone for a day but now it is back! It is random...and it sounds like it is coming from above my head. Since I need to be in motion and on a CERTAIN kind of terrain to here it, it is a pain in the butt to diagnose (while driving).
