NHTSA Complaint #11196031 — 2002 CHEVROLET IMPALA

ON APRIL 9TH OF 2017, OUR 2002 IMPALA LS WAS BROUGHT IN TO HAVE THE VEHICLE SERVICED DUE TO THIS RECALL: THESE VEHICLES HAVE A CONDITION IN WHICH DROPS OF ENGINE OIL MAY BE DEPOSITED ON THE EXHAUST MANIFOLD THROUGH HARD BRAKING, WHICH MAY RESULT IN AN UNDER HOOD FIRE. THIS WORK WAS DONE IN APRIL 2017: DEALERS WILL REPLACE THE ENGINES FRONT VALVE COVER AND FRONT-VALVE-COVER GASKET WITH NEW PARTS OF AN IMPROVED DESIGN AND REMOVE THE ENGINES PLASTIC COVER AND PLASTIC OIL-FILL-TUBE EXTENSION. SUMMER OF 2017 WE HAD THE OIL AND FILTER REPLACED, AND AFTERWARDS LOTS OF SMOKE CAME FROM ENGINE. WE THOUGHT THE MECHANIC HAD SIMPLY SPILLED SOME OIL ON THE ENGINE. SUMMER OF 2018 OIL AND FILTER WAS CHANGED AND SMOKE FROM THE ENGINE COMPARTMENT, WE AGAIN THOUGHT THE MECHANIC HAD SPILLED SOME OIL ON THE ENGINE. IN MARCH OF 2019 THE VEHICLE WAS PARKED, FACING DOWNHILL AT AN ABOVE AVERAGE ANGLE, AND OIL BEGAN TO SEEP OUT OF THE ENGINE AND BURN OF ON THE HOT EXHAUST MANIFOLD LOTS OF SMOKE AND POTENTIAL FIRE HAZARD. THE VEHICLE WAS RETURNED TO BOB MCCOSH, WHO HAD PERFORMED THE ORIGINAL GASKET REPLACEMENT IN 2017, TO HAVE THE ORIGINAL RECALL WORK INSPECTED. UPON INSPECTION A PIECE OF GASKET, ABOUT 2 TO 3 INCHES LONG, WAS FOUND TO BE PROTRUDING FROM BETWEEN THE VALVE COVER AND THE ENGINE. UPON FURTHER INSPECTION OF THIS GASKET, THE EDGE OF THE GASKET VISUALLY APPEARED TO HAVE BEEN CAUGHT BY THE BOLT AS IT WAS TIGHTENED AND THIS EITHER TORE THE GASKET OR WEAKENED IT SUFFICIENTLY SO THAT THE GASKET FAILED. SAID GASKET IS CURRENTLY IN MY POSSESSION. WE KNOW IT FAILED BEFORE THE OIL/FILTER CHANGE IN THE SUMMER OF 2017, BECAUSE OF THE AMOUNT OF SMOKE THAT ISSUED FROM THE ENGINE COMPARTMENT AFTERWARDS. THIS RECALL REPAIR LASTED FAR LESS THAN THE 12MONTH/12,000 MILE WARRANTY. THE VEHICLE, TODAY APRIL 2019, STILL HAS LESS THAN 10,000 MILES SINCE THE ORIGINAL RECALL WORK WAS DONE IN MARCH 2017.
