DROVE FROM MY HOME TO COWORKERS (20MINS) LEFT TRUCK IN COWORKERS DRIVEWAY ,AND WENT TO WORK. ONE HOUR LATER COWORKER REC'D CALL FROM NEXT DOOR THAT MY TRUCK WAS ON FIRE.
I SMELLED EXHAUST FUMES IN THE CAB OF THE PICKUP TRUCK AND HEARD A SHRIEKING SOUND UNDER THE HOOD. I HAD TO PUT THE WINDOW DOWN TO RELIEVE MY DIZZINESS FROM THE FUMES. UPON INVESTIGATION I FOUND 3 OF THE 6 BOLTS BROKEN THAT FASTEN THE EXHAUST MANIFOLD TO THE ENGINE. EXHAUST FUMES ARE LEAKING FROM THE BURNED OUT GASKET. *TR
EXHAUST MANIFOLD BOLTS BREAKING OFF CAUSING EXHAUST LEAK WHERE MANIFOLD BOLTS ONTO HEAD. DUE TO EXHAUST LEAK NOW VEHICLE IS THROWING CODES FOR CATALYTIC THRESHOLD LOW. WHICH LEADS TO A MAGNITUDE OF PROBLEMS TO LACK OF POWER, POOR FUEL MILEAGE AND NOT BEING ABLE TO PASS EMISSION TEST IN SOME STATES. PROBLEM RESULTS IN UPWARD OF THOUSAND DOLLARS IN REPAIR FOR FAULTY BOLTS, AFTER RESEARCHING SAID PROBLEM IT IS A COMMON PROBLEM WITH GM V8 OF THIS YEAR OLDER AND NEWER AS WELL. THIS IS A MAJOR DEFECT AND FLAW IN GM'S DESIGN AND NEEDS TO BE ADDRESSED ASPA!!! THIS IS A PROB THAT IS AFFECTING EPA LAWS AND NEEDS ACTION TAKEN AGAINST GM TO FIX THIS PROBLEM BEFORE IT GETS WORSE. GM NEEDS TO BE HELD RESPONSIBLE FOR THEIR VEHICLES AND POOR DESIGN AND OR PRODUCTS THAT GO INTO THEM THAT CAUSES LAWS OR SAFETY TO BE BROKEN OR EFFECTED! *JS
AT THE ABOVE LISTED DATE MY VEHICLE BEGAN BLOWING EXCESSIVE BLUE SMOKE THROUGH THE EXHAUST. I DISCOVERED AT THAT TIME THERE HAD BEEN A RECALL ON THE FUEL INJECTORS SEVERAL YEARS BEFORE. I ATTEMPTED TO REMEDY THIS WITH GM AT THAT TIME AND WAS TOLD I WAS TOO LATE PAST THE DATE TO GET SERVICE ON THE RECALL. I WAS NOT NOTIFIED OF A RECALL AND WOULD HAVE TAKEN CARE OF IT AT THAT TIME. IT CONTINUES TO BLOW EXCESSIVE SMOKE BUT ONLY AT IDLE. I WISH TO HAVE THE PROBLEM CORRECTED AS IT IS HURTING THE ENVIRONMENT. I WAS GIVEN A PRICE AT THE LOCAL DEALERSHIP TO REPAIR THIS ISSUE. I DON'T FEEL I SHOULD HAVE TO PAY TO HAVE IT CORRECTED AS THERE WAS A RECALL ON THE PROBLEM. *TR
MULTIPLE EXHAUST MANIFOLD BOLTS ARE BROKEN ON EACH SIDE. *TR
