Bought a car almost 2 weeks ago. Was told to bring the car in for service because of a light coming on right after leaving leaving the lot. and they would make it right. Only had the car for 3 days before we dropped it off. No one can tell us anything thats going on with it. Just worried we are mad. Of course I'm mad! It's been over a week with no answers.
