2001 GMC Sierra Engine Problems

WHEN MY ISSUES STARTED, I WOULD FILL MY GAS TANK AND THE GAS GAUGE WOULD PLUMMET TO EMPTY. WHILE DRIVING, IT WOULD GO TO FULL, BACK TO EMPTY OR BE ANYWHERE IN BETWEEN. AT THAT TIME, THERE NO NO MECHANICAL ISSUES, JUST THE ANNOYING FACT THAT YOU HAD NO IDEA HOW MUCH FUEL YOU ACTUALLY HAD. THIS WENT ON UNTIL THIS SPRING, WHEN I HAD THE FIRST POTENTIALLY DANGEROUS INCIDENT. I WAS DRIVING DOWN A COUNTY HIGHWAY AT APPROXIMATELY THE SPEED LIMIT AND THE TRUCK'S ENGINE JUST SHUT OFF. NO POWER STEERING, NOTHING. IT HAPPENED JUST AS I WAS COMING TO A STOP SIGN THANKFULLY. I WAS ABOUT 50 MILES FROM HOME AND WAS ABLE TO CALL A FRIEND THAT MANAGES THE COLLISION CENTER OF A LOCAL CAR DEALERSHIP TO SEE ABOUT GETTING A TOW OR HIS OPINION AS TO WHAT WAS WRONG. AFTER ABOUT TEN MINUTES AND AFTER NUMEROUS ATTEMPTS, IT RESTARTED. I TALKED TO SEVERAL MECHANICS AND GOT THE SAME ANSWER FROM ALL OF THEM: THE FUEL PUMP AND SENDING UNIT FAIL IN GMC TRUCKS AROUND THE MILEAGE, 95,000 MILES, THAT I CURRENTLY HAVE ON THE TRUCK. THE GAS GAUGE IS STILL ERRATIC, I HAVE HAD TWO EPISODES OF THE VEHICLE STALLING AND NOW THE SERVICE ENGINE SOON LIGHT IS COMING ON AND WHEN IT IS PUT ON AN ANALYZER IT SAYS EMISSIONS, BUT THERE IS NOTHING WRONG WITH THE EMISSIONS SYSTEM. I HAVE ALSO TALKED TO OWNERS WHO HAVE HAD THEIRS REPLACED AND EVERYONE SAYS TO GET A FACTORY MADE PUMP BECAUSE THE CHEAP AFTERMARKETS BREAK DOWN EVEN QUICKER. I GOOGLED THE INFORMATION AND THE PROBLEM APPEARS TO BE WIDESPREAD. *TR

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

DISC ROTOR DELAMINATION, ANTI-LOCK CONTROL. I WAS PULLING A 3/4 TON VAN STUCK IN HIS YARD, AS I GOT HIM CLOSE TO THE HARD SURFACE ( DRIVEWAY) I PUT ON THE BRAKES AND THE TRUCK WOULDN'T STOP, IT HIT THE CORNER OF HIS BLOCK HOUSE. NO DAMAGE TO THE HOUSE HOWEVER I HAD TO REPLACE ALL BUT HOOD AND ONE HEADLIGHT ASSY. 10 MPH AND NEITHER BAG DEPLOYED. I THOUGHT IT WAS MY OWN STUPIDITY UNTIL READING ALL THE ISSUES ON HERE W/ GM'S BRAKING PROBLEMS. I FEEL A BIT BETTER ABOUT MYSELF. THE BIG ISSUE !! ALL FOUR ROTORS DELAMINATED W/ 46,000 MILES THIS IS THE 1ST NEW TRUCK I'VE OWNED AND BELIEVE ME IT'S BEEN BABIED FOR SURE. I WAS TOLD BY MY SERVICE DEALER THERE WAS NOTHING GM WOULD DO ABOUT THIS PROBLEM IT WAS MY PROBLEM FOR NOT DRIVING IT AS MUCH AS I SHOULD (B.S.) DEALER WANTED TO CHARGE ME A GRAND TO REPLACE ALL THE ROTORS AND PADS I DID IT FOR 500.00 AND STILL HAVE THE OLD PARTS. I'M SURE GM SHOULD ISSUE A RECALL ON THIS, IT IS A DEFINITE SAFETY ISSUE DID I FAIL TO MENTION THE MUFFLER HAD A RATTLE IN IT AND WAS REPLACED WITHIN THE 1ST 1000 MILES, THE THUMP IN THE STEERING COLUMN THAT HAS NO WAY TO BE LUBRICATED. MAN I AM DISAPPOINTED IN GM PRODUCTS. *JB

MY 2001 GMC SIERRA HAS A TENDENCY TO USE OIL. IT HAPPENS AFTER ABOUT 3000 KMS AFTER AN OIL CHANGE. I BROUGHT IT UP TO THE SERVICE DEPARTMENT AT THE DEALERSHIP AND THEY TOLD ME TO TRY A DIFFERENT BRAND OF OIL. I ALSO COMPLAINED ABOUT MY TRUCK ROLLS AHEAD WHEN I START IT IN COLD WEATHER. THEY SAID THAT THIS IS NORMAL. THAT IS THEIR ANSWER FOR EVERYTHING!!! AS FAR AS I AM CONCERNED, WHEN A VEHICLE IS IN PARK IT SHOULD NOT MOVE WHEN YOU START IT!!!! *JB

ENGINE KNOCKS WHEN STARTING COLD AND WHEN PULLING A TRAILER OR UNDER A LOAD. TOOK TRUCK TO DEALER AND WAS ADVISED THAT ALL THE 5.3 LITER ENGINES WILL EVENTUALLY DO IT. ALSO SAID THAT GENERAL MOTORS IS AWARE OF THE PROBLEM. I THEN CALLED GENERAL MOTORS AND ASKED THEM ABOUT THE PROBLEM. THEY SAID THAT IT WAS A CARBON BUILD UP. SO THEY HAD THE DEALER DO A DECARBONASATION WHICH REMOVES THE CARBON BUILD UP. WHEN IT WAS FINISHED, IT WAS WORSE THAN IT WAS BEFORE THEY WORKED ON IT. I CALLED GENERAL MOTORS BACK AND THEN THEY TOLD ME THAT THE PISTONS ARE SMALLER THAN NORMAL AND THAT THEY ARE SLAPPING AROUND IN THE CYLINDER WALLS CAUSING THE KNOCKING NOISE, AND THAT THEY ARE NOT DOING NOTHING ABOUT IT BECAUSE IT IS NOT DOING ANY DAMAGE TO THE MOTOR. THEY OFFERED ME AN EXTENDED WARRANTY ON THE DRIVE TRAIN AND I DECLINED IT. I PAID FOR A QUIET RUNNING GAS MOTOR, NOT ONE THAT SOUNDS LIKE A DIESEL. THE KNOCKING NOISE DECREASES THE TRADE IN VALUE, REGARDLESS IF IT IS DAMAGING THE MOTOR OR NOT. IF I WANTED A DIESEL I WOULD HAVE BOUGHT ONE. I HAVE BEEN GOING ROUND AND ROUND WITH GM AND THE DEALER FOR ALMOST TWO YEARS AND HAVE GOT NOWHERE.

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

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 CAN HANDLE THE TASK OF GETTING OIL TO THE CRANK CASE. *TS *NLM ****DIMSII IVOQ ENTRY POSTED AFTER 12-12-02 CUT OVER TO ARTEMIS****761983

THE SAFTY DEFECT IS THAT THE ENGINE JUST QUITS AT ANY SPEED. THE SAME PROBLEM HAPPENED TWO TIMES. ONCE AT 3793 MILES ON APRIL 5, 2001 AND THEN AGAIN AT 6340 MILES ON MAY 15, 2001. BOTH TIMES THE ENGINE BEGAN TO PING AND THEN JUST STOPPED RUNNING. BOTH SITUATIONS HAPPENED WHILE ON A MAJOR HIGHWAY AT HIGHWAY SPEEDS. I WAS LUCKY ENOUGH TO BE ABLE TO GET TO A SHOULDER LANE ON THE HIGHWAYS. THE SAFETY PROBLEM IS IF THE TRUCK SHOULD STOP AT A LOCATION WHERE ROAD REPAIRS ARE IN PROGRESS AND THE SHOULDER LANES ARE BLOCKED BY CEMENT BARRIERS TO NOT ALLOW ME TO GET OFF OF THE HIGHWAY LANES WITH HEAVY TRUCK TRAFFIC. THIS IS NOT HYPOTHETICAL, I DRIVE HWY 35 BETWEEN SAN ANTONIO AND DALLAS AND THE HIGHWAY IS ALLWAYS UNDER REPAIR, THE CEMENT BARRIERS ARE UP AND THE HEAVY TRUCK TRAFFIC IS THERE. THE DISASTER WAITING TO HAPPEN IS THE TRUCK STALLING AT THESE LOCATIONS.*AK
