NHTSA Complaint #10577890 — 2008 PONTIAC GRAND PRIX

2008 PONTIAC GRAND PRIX ENGINE WILL AUTOMATICALLY STOP RUNNING WHEN DRIVING. THIS SHUTS DOWN THE POWER STEERING, BRAKES, ETC. THIS HAS HAPPENED ABOUT A DOZEN TIMES OVER THE LAST YEAR. ALL BUT TWO TIMES WHEN THIS HAPPENED, WE WERE ABLE TO PUT THE CAR IN NEUTRAL AND RESTART THE CAR. TWO OF THE TIMES, THE CAR DID NOT WANT TO START - CAR WOULD CRANK BUT NOT START. EVENTUALLY WE WERE ABLE TO GET THE CAR STATED. OVER THE PAST YEAR THIS HAPPENED WHEN WE WERE DRIVING IN A CITY AT APPROXIMATE 30 MPH, COASTING DOWN A HILL, OR STOPPED AT A STOP SIGN. HOWEVER, WE DID NOT TAKE THIS CAR ON THE HIGHWAY VERY OFTEN SO WE HAVE NOT HAD THIS ISSUE HAPPEN ON THE HIGHWAY. SO FAR, WE HAVE BEEN LUCKY AND HAD NO ACCIDENTS WITH THE CAR. SYMPTOM'S ARE VERY SIMILAR TO THE GM IGNITION SWITCH RECALL. WE TOOK THE CAR TO TWO REPAIR PLACES AND THE DIAGNOSTICS WOULD NOT SHOW ANYTHING. WE RECENTLY TOOK THE CAR TO A GM DEALER AND THEY RAN A DIAGNOSTICS AND THEY DETERMINED CRANKSHAFT POSITION SENSOR CODE P0335. THEY REPLACED 10456161 SENSOR AND EMISSIONS SYSTEM REPAIR. THEY ARE NOT 100% SURE THAT THIS WILL FIX THE PROBLEM. THIS IS A VERY DANGEROUS SITUATION AND WE DO NOT ALLOW OUR KIDS TO DRIVE THE CAR FOR FEAR OF THEM BEING KILLED IN AN ACCIDENT. *TR
