NHTSA Complaint #11322021 — 2003 CHEVROLET IMPALA

THE INCIDENT HAPPENED THIS MORNING AS I WAS LEAVING FOR WORK. MY CAR WAS PARKED IN OUR DRIVEWAY AND HAD NOT BEEN DRIVEN IN 2 DAYS. I GOT IN THE VEHICLE AND PUT THE KEY IN THE IGNITION AND AS SOON AS I TURNED IT TO START THERE WAS A LOUD BANG THAT SOUNDED LIKE A GUNSHOT WHICH I THOUGHT WAS A BACKFIRE. THE ENTIRE PLASTIC INTAKE MANIFOLD GASKET HAD EXPLODED INTO PIECES AND WHITE SMOKE BEGAN TO RISE FROM UNDER THE HOOD. WHEN I OPENED THE HOOD AND THE SMOKE CLEARED I BEGAN TO ASSESS THE ISSUE, I NOTICED THE MANIFOLD GASKET COVER HAD BEEN BLOWN COMPLETELY OFF AND THE MANIFOLD ITSELF WAS IN PIECES. I'VE DONE SOME RESEARCH AND THIS SEEMS TO BE A COMMON BUT UNCOMMON THING AMONG EARLY 2000'S GM VEHICLES.
