CAR WILL RE-START ON ITS OWN AFTER KEY IS REMOVED.

IT THEN CANNOT BE TURNED OFF BECAUSE THE IGNITION SWITCH IS ALREADY IN THE OFF POSITION. THE ONLY WAY TO SHUT OFF THE ENGINE IS TO JIGGLE THE SHIFTER.

I RECEIVED A RECALL REPAIR FOR MY 2002 PONTIAC BONNEVILLE-CAMPAIGN #03034. IF I HAD REPLACED THE UPPER INTAKE MANIFOLD GASKET, THROTTLE BODY NUTS, OR THROTTLE BODY GASKET BEFORE AUGUST 8, 2003, I WOULD HAVE BEEN ELIGIBLE FOR REIMBURSEMENT. SINCE I ONLY HAD OWNED THE CAR FOR 1 YEAR AT THAT TIME AND HAD NOT REPLACED THESE ITEMS, I HAD A RECALL REPAIR DONE ON 11-10-03. I MENTIONED AT THE TIME THAT WHEN I COME INTO MY GARAGE, I COULD SMELL HOT COOLANT. THE SHOP FOLLOWED THE INSTRUCTIONS OF THE RECALL REPAIR TO REPLACE THE THROTTLE BODY NUTS AND ADDED SOMETHING SIMILAR TO A "STOP LEAK". WE TRIED AT THAT TIME TO GET A BETTER "FIX" TO PROPERLY REPAIR POSSIBLE PROBLEM, BUT THIS IS ALL SHOP WOULD DO. NOW, AFTER MY WARRANTY IS OVER, I WAS TOLD THAT I NEED TO REPLACE MY UPPER INTAKE GASKET KIT SINCE THE INTAKE MANIFOLD GASKET IS LEAKING COOLANT EXTERNALLY. *JB
