2002 GMC Sierra 2500 engine problems

ENGINE

THREE BROKEN MANIFOLD BOLTS. FROM WHAT I HEAR THIS IS A COMMON OCCURRENCE. THE BROKEN ONE CLOSE TO FIREWALL, WILL HAVE TO PULL ENGINE TO FIX. THERE SHOULD BE A RECALL ON THESE MANIFOLD BOLTS.

NHTSA complaint #10572622 — an unverified report by a vehicle owner.

ENGINE

THE TRUCK HAS SEVERAL BROKEN EXHAUST MANIFOLD STUDS THAT ARE COMPLETELY RUSTED OUT CAUSING FAILURE OF CORRECT EMISSION CONTROLS THROUGH THE CATALYTIC CONVERTER, AND OUT OF THE HEADERS INSTEAD. THIS IS ENVIRONMENTALLY UNFRIENDLY, AND IS REALLY ANNOYING AS THE EXHAUST LEAKS FROM UNDER THE HOOD DUE TO LACK OF BOLTS ON THE EXHAUST MANIFOLD.

2002 GMC SIERRA 2500HD. CONSUMER STATES PROBLEM WITH VEHICLE ENGINE *TGW THE CONSUMER STATED THE ENGINE WOULD SHUT DOWN WHILE DRIVING, LOOSING ALL POWER TO THE STEERING AND BRAKES, AND COULD NOT BE STARTED AGAIN, UNTIL THE TRUCK WAS PUT IN PARK AND THE KEY REMOVED FROM THE IGNITION. THERE WERE ALSO TIMES, WHEN THE TRUCK WOULD NOT START AT ALL. THE DEALER KEPT THE TRUCK FOR THREE WEEKS AND THEY WERE UNABLE TO DUPLICATE THE PROBLEM. WHEN THE CONSUMER PICKED THE TRUCK UP AND DROVE 10 MILES, IT SHUT DOWN AGAIN. THE CONSUMER BELIEVED THE PROBLEM WAS FUEL RELATED.

ENGINE AND ENGINE COOLING:ENGINE

I HAVE A 2002 GMC SIERRA 2500HD WITH THE 8.1L ENGINE THAT IS EXHIBITING THE EXACT SAME SYMPTOMS THAT LED TO THE RECALL OF THE 2001 MODEL. (NHTSA # 07V521000). ONE MINUTE I'LL BE DRIVING DOWN THE FREEWAY AND THE NEXT MINUTE THE ENGINE WILL STOP RUNNING. THIS HAS HAPPENED NUMEROUS TIMES. SOMETIMES IT'LL RESTART BEFORE IT COMES TO A STOP. SOMETIMES IT WILL TAKE SEVERAL MINUTES AFTER IT'S COME TO A STOP. I'VE RESEARCHED IT ON-LINE, AND IT WOULD APPEAR THAT THIS PROBLEM IS NOT RESTRICTED TO THE 2001 MODELS. THE DATE I'VE LISTED IS WHEN I FIRST REMEMBER IT HAPPENING. IT'S VERY INTERMITTENT. IT'S GETTING WORSE.

ENGINE AND ENGINE COOLING

I HAVE A 2002 GMC SIERRA 2500HD PICKUP WITH THE VORTEC 8.1 ENGINE. I AM EXPERIENCING THE SAME CRANK POSITION SENSOR FAILURE AS EXPERIENCED IN THE 2001 MODEL YEAR RECALL (SAFETY RECALL # 06083). I AM NOT ALONE, AS MANY MANY OTHERS ARE HAVING THE SAME ISSUES IN THEIR 2002-2004 PICKUP TRUCKS. I BELIEVE THE NHTSA SHOULD EXTEND SAFETY RECALL # 06083 TO INCLUDE MODEL YEARS 2002 TO 2004, AS SOME MODELS MANUFACTURED IN CANADA FREQUENTLY USE PARTS FROM PREVIOUS US MODEL YEARS. MY VEHICLE IS NOT SAFE TO OPERATE ON THE HIGHWAYS AS A RESULT. PLEASE ADVISE.
