Scared the crap out of me when the light didn't go out after turning the car on and moving it not even 15ft from the grass. It's at the dealer now and there running a full diagonostic on it as we speak. Any ideas as to what could've cause the light to come on and stay on? I didn't wash under the hood or get any water near the computer and yes the gas cap is tightened as far as 4 clicks after getting screwed back in. I hope its nothing major. Im still waiting for them to call.
