I OWN A 2002 CHEVROLET SILVERADO 2500HD WITH 8.1L ENGINE. THE TRUCK HAS STARTED STALLING (ENGINE COMPLETELY SHUTTING DOWN) WHILE I AM DRIVING AT DIFFERENT SPEEDS. THIS HAS HAPPENED AT LEAST 7 OR 8 TIMES NOW. THIS IS VERY DANGEROUS BECAUSE YOU NEVER KNOW WHEN IT IS GOING TO HAPPEN OR HOW FAST YOU MAY BE GOING. SO FAR, I HAVE REPLACED BATTERY, BATTERY CABLES, HAD THE FUEL LINES SERVICED, AND HAD THE FUEL INJECTORS CLEANED. AFTER DOING A LITTLE RESEARCH, IT APPEARS THAT THE CRANKSHAFT POSITION SENSOR IS THE ISSUE AS IS ON MANY OF THESE TRUCKS. THERE WAS A RECALL ON THE 2001 TRUCKS FOR THIS ISSUE BUT NOT ON THE 2002 TRUCKS FOR SOME REASON. COSTLY TO FIX THIS ISSUE. MY TRUCK ONLY HAS 67,000 MILES ON IT. *TR
CHEVY 2002 SILVERADO, WITH 8.1L ENGINE, STALLS WITHOUT WARNING RANDOMLY. FOUND PROBLEM CODE P0335 LOGGED ON DIAGNOSTIC ANALYZER (CRANKSHAFT POSITION SENSOR CIRCUIT A). CONTACTED DEALER AND THEY INFORMED ME THAT THERE IS A RECALL FOR MODEL YEAR 2001, BUT NOT 2002. SCHEDULED FOR REPAIR THIS WEEK. *TR

TL*THE CONTACT OWNS A 2002 CHEVROLET SILVERADO 2500 HD. THE CONTACT STATED THAT THE VEHICLE WOULD INTERMITTENTLY SHUT OFF. AT TIMES, IT WOULD RUN VERY ROUGH BUT IT WOULD JUST SUDDENLY SHUT OFF. HE HAD TO SIT AND WAIT A PERIOD OF TIME BEFORE HE COULD RESTART THE VEHICLE. THE FAILURE OCCURRED TWELVE TIMES SINCE JULY 2009. THE VEHICLE WAS TAKEN TO A REPAIR SHOP WHERE THE MECHANIC SUSPECTED THAT THE FAILURE WAS CAUSED BY A DEFECTIVE CRANKSHAFT SENSOR; THE MECHANIC COULD NOT PRODUCE ANY CODES AFTER THE DIAGNOSTIC TEST WAS PERFORMED. THE VEHICLE HAD NOT BEEN REPAIRED AT THE TIME OF THE COMPLAINT. THE CURRENT MILEAGE WAS APPROXIMATELY 98,000. THE FAILURE MILEAGE WAS APPROXIMATELY 85,000.

I HAVE A 2002 CHEVROLET 2500HD PICKUP WITH THE DURAMAX DIESEL ENGINE WITH JUST OVER 100,000 MILES ON IT. RECENTLY, WHILE SITTING AT A STOP SIGN, DARIK SMOKE WOULD COME FROM THE EXHAUST. IT NEVER DID THIS BEFORE SO I TOOK IT TO THE LOCAL DEALER TO FIND OUT WHAT THE PROBLEM MIGHT BE. THE DEALER TOLD ME THAT THE INJECTORS NEEDED TO BE REPLACED AT A COST OF ABOUT $4500. I CONTACTED GMC, THEY SET UP A CASE FILE AND GOT BACK TO ME IN ABOUT A WEEK TO TELL ME THAT I WAS BEYOND THE 7 YEAR EXTENDED WARRANTY AND SO THEY WOULD NOT COVER THE REPAIR. THE FACT THAT IT ONLY HAD ABOUT 1/2 OF THE 200,000 MILES COVERED IN THE EXTENDED WARRANTY DIDN'T SEEM TO COUNT FOR ANYTHING. ONE OF THE SELLING POINTS WHEN I PURCHASED THE VEHICLE WAS THAT IT SHOULD LAST FOR 200K TO 300K MILES WITHOUT NEEDING REPAIR. THE VEHICLE HAS BEEN USED PRIMARILY FOR PERSONAL TRANSPORTATION, NOT ABUSED, WITH ONLY OCCASIONAL TOWING OF A RELATIVELY LIGHT TRAILER. *TR

THE CAR WAS OPERATING NORMALLY AS I WAS LEAVING THE PARKING LOT AFTER SHOPPING. THE ENGINE WAS AT NORMAL OPERATING TEMPERATURE. THE ENGINE STALLED, LOST POWER BRAKES AND STEERING. THIS OCCURRED FIVE TIMES IN A PERIOD OF APPROXIMATELY ONE WEEK. THE ENGINE WOULD RESTART AFTER ONE MINUTE OR MORE. THERE WERE NO SES OR MIL INDICATIONS OR DTC CODES. I GOOGLED THE FAILURE AND FOUND SEVERAL PEOPLE WITH SAME PROBLEM. I ALSO FOUND A NHTSA RECALL 06083 FOR A 2001 YEAR MY VEHICLE IS A 2002. I TOOK THE VEHICLE TO THE CHEVROLET DEALER AND HAD THE CRANKCASE POSITION SENSOR REPLACED AND THAT SOLVED THE PROBLEM. TO ELABORATE ON THE PROBLEM IT DID OCCUR WHILE I WAS DRIVING DOWN THE HIGHWAY AT 65 MILES PER HOUR. THAT IS VERY SCARY AND AS THIS IS A TRUCK I COULD HAVE BEEN TOWING MY BOAT. I DO HAVE THE DEFECTIVE PART. IT SEEMS TO ME THAT ALL THE DEFECTIVE PARTS WERE NOT REMOVED FROM INVENTORY OR THE SOLUTION TO THE PROBLEM WAS INADEQUATE. *TR
BROKEN EXHAUST MANIFOLD BOLTS. *TR
