I'd go straight back to the Service Center and let them know what is happening. That does not sound good or like something you should wait on.
You have a 2 day money-back period - so yes - I would say so - if they can't remedy it right then and there - I would certainly do as you suggested and just refuse the car at that point and ask for either a new one or a refund.
No matter what it is, only the service center can diagnose and effect a repair. Those guys can work magic.
They couldn’t look at it for a few hours so I decided to not take it. I was willing to overlook the minor paint issues and the fact that the roof glass had to be replaced, but that noise was the final straw. Back on the list i go, anyone have any recommendations to get a new vin faster.
