NHTSA Complaint #10154674 — 2004 PONTIAC GRAND PRIX

COMPLETELY RANDOM AND INTERMITTENT STARTING PROBLEM. ON SOME STARTS, VEHICLE WILL TURN OVER, AND CATCH, BUT WHEN RPM'S REV UP THEN COME BACK DOWN, CAR STALLS OUT. NO CONSEQUENCES, AS THE VEHICLE HAS NEVER STALLED WHILE DRIVING. ONCE THIS OCCURS, DRIVER MUST APPLY LIGHT THROTTLE WHEN TURNING VEHICLE OVER AGAIN, IN ORDER TO MAKE IT CATCH. HAVE CONTACTED DEALER, AS WELL AS GM CANADA, AND BOTH BELIEVE IT TO BE A COLD WEATHER START PROBLEM, HOWEVER, THIS HAS OCCURRED IN ALL 4 SEASONS, EVEN AFTER DRIVING CAR FOR A WHILE, THEN LEAVING FOR 10 MINUTES AND COMING BACK. CAR IS CURRENTLY BEING DRIVEN BY DEALERSHIP SERVICE MANAGER FOR HIM TO TROUBLE SHOOT PROBLEM AND EXPERIENCE SYMPTOMS. VEHICLE HAS NOT LEFT US STRANDED, HOWEVER, PROBLEM IS FRUSTRATING AND SEEMS TO BE GETTING WORSE. *JB
