2001 GMC SIERRA Engine And Engine Coolingengine Problems

I WAS DRIVING DOWN THE ROAD, AND THE VEHICLE STOPPED RUNNING, SOME SECONDS LATER IT RESTARTED. TWICE SINCE THEN THE VEHICLE WOULD NOT START, BUT THEN STARTED SOMETIME LATER. I HAD THE VEHICLE REPAIRED AT SHARON CHEVROLET, THEY FOUND A CODE THAT INDICATED THE CRANK POSITION SENSOR (CKP) WAS AT FAULT. THIS HAS CORRECTED THE PROBLEM. I SPOKE TO GM AND THEY SAID IT WAS NOT ON RECALL. THIS COST ME $356.30 TO REPAIR, AND IT IS EXACTLY WAS IS ON ID #07V521000 RECALL. *TR

TL*THE CONTACT OWNS A 2001 GMC SIERRA. WHILE DRIVING APPROXIMATELY 15 MPH ON NORMAL ROAD CONDITIONS, THE ENGINE STALLED. ALL OF THE WARNING INDICATORS ILLUMINATED ON THE INSTRUMENT PANEL. THE ENGINE IMMEDIATELY RESTARTED WITHOUT ASSISTANCE AND THE VEHICLE BEGAN TO OPERATE NORMALLY. THE SERVICE ENGINE WARNING INDICATOR REMAINED LIT UNTIL THE ENGINE WAS TURNED OFF. THE VEHICLE WAS TAKEN TO AN AUTHORIZED DEALER FOR INSPECTION AND THEY STATED THAT THE FAILURE WAS RELATED TO THE CRANKSHAFT POSITION SENSOR. THROUGH RESEARCH, THE CONTACT DISCOVERED NHTSA CAMPAIGN ID NUMBER 07V521000 (ENGINE AND ENGINE COOLING). HE WAS INFORMED THAT THE VIN WAS EXCLUDED FROM THE RECALL, ALTHOUGH THE FAILURES WERE IDENTICAL. THE VEHICLE HAS NOT BEEN REPAIRED. THE FAILURE MILEAGE WAS 50,000 AND CURRENT MILEAGE WAS 65,000.

WHILE PARKING ON AN ICY PAVEMENT, THE ABS FAILED AND CAUSED THE VEHICLE TO HIT AND ROLL OVER THE CONCRETE PARKING DIVIDER. VEHICLE WAS TAKEN TO THE DEALER. THE DEALER CLEANED THE CORROSION OFF BOTH FRONT WHEEL SENSORS. THE CONSUMER STATED THAT HIS BRAKES FAILED 3 TIMES UNDER 5MPH. THE CONSUMER STATED THAT THE VEHICLE ALSO HAS ENGINE TROUBLE AND HAS HAD TROUBLE SINCE PURCHASE. *TC

WHILE STARTING UP THE VEHICLE CONSUMER HEARD A KNOCKING NOISE COMING FROM THE VEHICLE. CONSUMER TOOK THE VEHICLE TO THE DEALER FOR INSPECTION, AND MECHANIC DETERMINED THAT THE KNOCKING NOISE WAS NORMAL. *AK

WHEN THE AIR CONDITIONER (A/C) IS USED IT TAKES AT LEAST EIGHT MINUTES FOR THE COOL AIR TO FLOW. THERE IS A FOUL ODOR COMING FROM THE VENTS THAT SMELLS LIKE ROTTEN EGGS. ALSO, CONSUMER IS CONCERNED WITH THE SOUND OF THE ENGINE. ALTHOUGH THE VEHICLE IS EQUIPPED WITH A GAS ENGINE, IT SOUNDS LIKE A DIESEL ENGINE. THERE IS A IRRITATING NOISE THAT OCCURS INTERMITTENTLY AT ANY SPEED. THE DEALER CLAIMS THAT THE NOISE IS NORMAL. *AK ENGINE BURNS 3 QTS. OF OIL EVERY 3000 MILES AND THE FUEL GAUGE ISN'T ACCURATE. *PH *NLM

I PURCHASED THIS TRUCK WITH 13,000. MILES ON IT , RAN GREAT. AT 30000. MILES MOTOR STARTED TO PING LIKE A LIFTER WASN'T WORKING CORRECTLY. TOOK IT BACK TO DEALER WHERE I BOUGHT IT, THEY SAID IT WOULD NOT MAKE NOISE. TOOK SERVICE WRITER OUT AND STARTED TRUCK, ENGINE MADE LOAD KNOCKING NOISE. HE STATED THAT GMC SAID THAT WAS NORMAL FOR THAT ENGINE AND THAT IT STARTS AT 10,000.-19,000. MILES. BEEN IN CONTACT WITH GMC. THEY STATE IT WON'T HURT MOTOR,I DON"T NO WHY IT WOULDN'T, METAL AGAINST METAL WILL WEAR WITH TIME!!!!!!!!THEY ARE WILLING TO GIVE A EXTENDED WARRANTY TO 100,000. MILES !!!! I DON"T WANT IT I WANT MY TRUCK FIXED UNDER THE WARRANTY 3YR/36,000 THAT I HAVE. IF THEY WON'T HONOR THAT WARRANTY WHAT MAKES ME THINK THEY WILL HONOR 100,000. WARRANTY. *NLM

THERE IS EXCESSIVE ENGINE NOISE, THAT THE DEALERSHIP HAS SAID IS ENGINE LIFTERS. ACCORDING TO THE DEALERSHIP GM HAS DIAGNOSED THE PROBLEM AS AN OIL PUMP ISSUE. THEY SAY THAT SUFFICIENT OIL IS NOT PUMPED TO THE ENGINE, SO THERE IS A LACK OF LUBRICATION. THE RESULT IS A TYPICAL "LIFTER STICKING" NOISE. THE DEALER SAYS THAT GM HAS NOT ISSUED ANY SORT OF A RECALL YET! IN FACT THEY SAY THERE IS NOT AN ADVERSE EFFECT OR DAMAGED BEING CAUSED TO THE ENGINE. I FIND THIS HARD TO BELIEVE AS PROPER LUBRICATION IS CRUCIAL TO MOTOR LONGEVITY. I BELIEVE THIS IS A RECALL ISSUE, AND THE LONG GM WAITS TO DIAGNOSE AND RECALL THIS PROBLEM, DAMAGE TO THIS VEHICLE WILL ONLY WORSEN. IF ALL ALLOWED TO GO LONG ENOUGH, I WOULD THINK GM WOULD BE LOOKING AT HAVING TO REPLACE MOTOR BLOCKS, RATHER THAN INSTALLING AN OIL PUMP THAT...

2001 GMC SIERRA Z71 WITH 5.3L VORTEC ENGINE. ENGINE KNOCKS LOUDLY FOR APPROXIMATELY 10 SECONDS ON EVERY COLD START. CALLED THE DEALER AND SPOKE WITH SERVICE DEPARTMENT. PERSON I SPOKE WITH STATED THAT "ALL 5.3 LITER ENGINES DO THAT" AND THAT IT WAS "NORMAL". I EMAILED GMC WITH MY CONCERN AND THEY REPLIED: WE HAVE CONTACTED YOUR DEALER TO REVIEW THIS CONCERN. ACCORDING TO THE INFORMATION THEY PROVIDED AND THAT WE HAVE HERE, THIS TICK IS A CHARACTERISTIC OF THIS ENGINE. IT HAS BEEN DETERMINED THAT THIS TICK IS NOT INDICATIVE OF ANY DAMAGE BEING DONE TO THE ENGINE AND DOES NOT COMPROMISE THE LONGEVITY OR DURABILITY OF THE ENGINE OR ITS COMPONENTS. YOUR DEALER MAY BE ABLE TO PROVIDE YOU WITH ADDITIONAL INFORMATION REGARDING THIS MATTER. TS
