Buy an OBDII scanner or software and check it yourself. If they are blowing you off for a real fault, that's in violation of the Federal Clean Air Act and you can complain to the Federal Trade Commission. I've never had the dealer not tell me what the fault code was for. Talk to the service manager or owner. If not get a lawyer and file a lemon law lawsuit and watch the fun and excitement.
