Took it into the dealer today, and the light went out just before I arrived. They put it on the computer anyway and confirmed it was the gas cap vapor lock and not an emissions problem. Whew!!! A little frustrating but at least there was nothing wrong with my brand new car. I guess the person who filled up the tank for delivery, left the cap loose. It then took 2 days and 100 miles for the light to come on. Strange, but lesson learned.
