NHTSA Complaint #10327611 — 2004 CHEVROLET IMPALA

MY CAR WOULD RANDOMLY TURN OFF WHILE DRIVING ON THE STREETS AND ON THE MIDDLE OF THE HIGHWAY GOING 55 MILES PER HOUR, OR WHILE STOPPED AT A LIGHT . THE CAR WOULD STALL UP TO 3-4 TIMES PER DAY MOST OF THE TIME AND AS TIME WENT ON IT GOT WORSE. I REPLACED THE FUEL PUMP, FUEL PRESSURE REGULATOR, THE BATTERY, THE FUEL FILTER, THE IGNITION SWITCH, AND THE CAR STILL TURNS OFF IN THE MIDDLE OF NOWHERE. THE LAST TIME IT HAPPENED WAS WHEN MY WIFE WAS DRIVING TO WORK THE CAR STALLED A FEW YARDS AWAY FROM A RAILROAD CROSSING (SINCE SHE QUIT DRIVING ON EXPRESSWAY), LUCKILY IT DIDN'T HAPPEN ON TRACKS, NO TRAIN WAS COMING AT THAT TIME. SHE HAD TO WAIT APPROX. 25 MINS FOR IT TO START AFTER TRYING A FEW TIMES. THE NEXT DAY THE SAME THING HAPPENS BUT THIS TIME IT DIDN'T TURN ON, SO SHE CALLED THE DEALERSHIP AND THEY SENT A TOW TRUCK. THE TOW TRUCK DRIVER, WHEN HE ARRIVED APPROX. AN HOUR LATER, TRIED TO START IT BUT IT DIDN'T START EITHER. SO, WHEN ARRIVED AT THE DEALERSHIP THEY TRIED STARTING IT AND BY THEN IT STARTED. THE SHOP MANAGER, WHOM I HAD RELATED THIS INCIDENT TO WAS AWARE OF THE SITUATION, SO HE THEN ASSIGNED A MECH TO STAND BY THE ANALYZER MONITOR WHILE THE ENGINE WAS RUNNING. THEY KEPT THE ENGINE RUNNING UNTIL IT FINALLY DIED ON THEM AGAIN, WHILE THE MECH WAS STILL THERE, I DON'T KNOW HOW LONG (DIDN'T ASK). AT THIS PARTICULAR TIME THE ANALYZER INDICATED THAT THE CRANKSHAFT POSITION SENSOR WAS THE CAUSE OF THE STALL. NEEDLESS TO SAY IT WAS REPLACED AND IS NOW A MONTH LATER AND IT'S RUNNING JUST FINE. NOT A HINT OF STALLING NOR ANYTHING ELSE. MY CONCERN IS THAT ANYTHING CAN HAPPEN ON A HIGHWAY FROM A CAR THAT TURNS OFF RANDOMLY DUE TO THE CRANKSHAFT POSITION SENSOR. *TR
