Open the full vehicle complaint log (all categories)ON THE DURAMAX DIESEL, WHILE UNDER A LOAD (TOWING, FULL BED) FUEL LINES COLLAPSE CAUSING SEVERAL CHECK ENGINE LIGHTS AND VEHICLE TO GO INTO "LIMP" MODE. MUST RELEASE VACUUM IN FUEL SYSTEM (BY LOOSENING THE FUEL FILTER THEN RE-BLEEDING THE FUEL SYSTEM) IN ORDER FOR THE CODE TO GO OFF. HAPPENED SEVERAL TIMES, ONCE WHILE TOWING UP HILL. IF THIS HAD CAUSED AN ACCIDENT, I WOULD HAVE BEEN A GM SHARE HOLDER. VEHICLE HAS STALLED OUT SEVERAL TIMES IN THE WINTER DUE TO A COMBINATION OF THE WINTER DIESEL AND THE VACUUM FUEL SYSTEM. ONCE WHILE ON AN ICY ROAD, ON MY WAY TO WORK AT 4AM. GM NEEDS TO RECALL THIS. *TR
TWO THINGS STARTED TO HAPPEN 1. THE TRUCK WHEN COMING TO A STOP OF A SPEED OF LESS THEN 25 MPH STARTED TO LOSE ITS BRAKES AND FEEL SPONGY. THIS CONTINUED UNTIL I GOT IT IN THE SHOP WHICH WAS ABOUT TWO DAYS. 2. THE TRUCK STARTED TO RUN VERY ROUGH AND THE ENGINE LIGHT WAS COMING ON AT THE SAME TIME AS WELL. AFTER I GOT IT IN THE SHOP AND THEY GOT IT UP ON A LIFT THEY FOUND THAT ALL OF THE BRAKE LINES AND FUEL LINES WERE ALL MOST RUSTED THROUGH AND STARTING TO LEAK. THEY HAD TO REPLACE ALL OF THE BRAKE LINES, FUEL LINES AND SINCE THEY HAD THE FUEL TANK DOWN THEY REPLACED THE FUEL PUMP BECAUSE THEY FOUND RUST AND DIRT IN THE OLD PUMP. THE SHOP MECHANIC SAID THE LINES WERE READY TO FAIL AT ANY MOMENT. THE CHEVY DEALER I BOUGHT THE TRUCK OFF OF JUST FOUR MONTHS EARLY HAD JUST INSPECTED IT AND HAD SEEN THE RUSTED LINES AND EVEN REPAIRED A PIECE OF ONE OF THE FUEL LINES BUT LEFT THE REST GO TO FAIL DOWN THE ROAD, THEY GAVE ME LITTLE TO NO HELP. THIS IS A HUGE PROBLEM, DANGEROUS AS WELL AS VERY EXPENSIVE ONE AND NEEDS LOOKED INTO. IS THERE ANY HELP I CAN GET FOR THIS PROBLEM?? *TR
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

THE FUEL GAUGE BEGAN JUMPING FROM FULL TO EMPTY REGARLESS OF THE ACTUAL AMOUNT OF FUEL IN THE TANK. I TOOK GM'S RECOMMENDATION TO PUT THEIR FUEL SYSTEM CLEANER INTO THE GAS TANK TO CLEAN THE CONTACTS ON THE FUEL SENDING UNIT. APPROXIMATELY 6 MONTHS LATER, THE CATALYTIC CONVERTER PLUGGED TO THE POINT THAT THE VEHICLE WOULD NOT RUN AND IT HAD TO BE REPLACED. NOW TOLD THAT ONLY WAY TO FIX THE FUEL GAUGE IS TO PULL THE GAS TANK AND REPLACE THE SENDING UNIT. SHOULD BE A RECALL FOR THIS FAULTY SENDING UNIT AND THE "QUICK FIX" THAT MANY PEOPLE PROBABLY TRY. APPROXIMATELY $400 TO FIX SENDING UNIT BECAUSE IT'S BUILT INTO THE GAS TANK, AND APPROXIMATELY $1000 TO REPLACE THE CATALYTIC CONVERTER.

GAS TANK FILLER NECK LEAKING FUEL. *JB
GASOLINE SENSOR OR COMPUTER INDICATOR SHOWS LOW FUEL AND GAS GAUGE SHOWS NO FUEL WHEN ENGINE COLD AND WEATHER IS COOL OR COLD OUTSIDE, REGARDLESS OF THE QUANTITY OF GAS IN THE TRUCKS TANK (FULL, 1/2, 3/4, ETC). THIS JUST RECENTLY HAPPENED AND ALSO FOUR TO SIX TIMES LAST WINTER. *NM
FUEL GAUGE READ EMPTY WHEN FULL, HALF THE TIME. GAUGE WILL SHUT OFF THEN COME ON. THIS PROBLEM STARTED 2 YRS AGO WITH ONLY 38,000 MILES. *TR
GAS FUEL GAUGE-: GAUGE REGISTERS EMPTY WHEN TANK IS FULL. REFUEL LIGHT COMES ON & STAYS ON. GAUGE BOUNCES BACK & FORTH & IS HARD TO TELL HOW MUCH FUEL IS ACTUALLY IN THE TANK. HAVE TO WATCH ODOMETER TO FIGURE OUT WHEN TO FILL TANK UP WITH GAS. ON -GOING PROBLEM!!!!! *NM
GAS GAUGE GOES TO EMPTY WITHOUT WARNING, EVEN AFTER FILLING UP THE TANK. "LOW FUEL" WARNING STAYS ON WHEN ON EMPTY, EVEN WHEN THERE'S PLENTY OF GAS IN THE TANK. THIS SHOULD NOT BE HAPPENING, GMC SHOULD TAKE CARE OF THERE CUSTOMERS. THIS IS MY SECOND GMC TRUCK, AND I BOUGHT THIS ONE BECAUSE OF THE QUALITY MY 1ST TRUCK WAS GOOD. MY WIFE WANTS ME TO BUY A TOYOTA NEXT TIME, THAT'S ALL SHE EVER OWNED. GMC TAKE CARE OF THIS PROBLEM, OR I'LL WON'T BE COMING BACK FOR A 3RD. *NM
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
FUEL GAUGE HAS NEVER WORKED PROPERLY( JUMPS FROM 1/2 TANK TO EMPTY) TODAY I WAS DRIVE ON ! 40 EAST AT THE POSTED SPEED OF 75 MPH WITH 1/2 TANK OF FUEL AND THE VEHICLE JUST SHUT DOWN, I DID GET SAFLEY TO THE SHOULDER, TO FIND I WAS OUT OF FUEL ...I T READ 1/2 TANK PREVIOUSLY I HAD HEARD OF THIS HAPPENING TO OTHER GMC OWNERS IN THIS AREA BUT IT WAS THEIR FUEL PUMPS. THE DEALER SAYS IT IS THE LOCAL REFINERY'S FALT FOR ADDITVIES IN THE FUEL .. AND THIS IS THE ONLY AREA WHERE THE FUEL SYSTEM IS BEING AFFECTED. MY EMPLOYEER HAD 2 FUEL PUMPS PUT IN HER NEW GMC YUKON IN 6 MONTHS, AT HER EXPENSE. I DO NOT WANT TO PAY FOR DEFECTIVE PARTS OR AN VEHICLE THAT IS UNSAFE FOR THE INTERSATE.
THE ACCELERATOR STICKS AND IS EXTREMELY DIFFICULT TO DEPRESS. THE CARBURETOR DESIGN ALLOWS CARBON TO BUILD UP IN THE THROTTLE BODY THROAT. I OFTEN HAVE TO "HIT" THE ACCELERATOR WITH MY FOOT TO DISLODGE THE BUTTERFLY. THIS HAPPENS WORSE AFTER THE VEHICLE HAS BEEN SETTING FOR AN HOUR OR SO. IT WILL ALSO HAPPEN AFTER DEPARTURE WHILE SETTING IN TRAFFIC OR AT STOP LIGHTS. I USE MID GRADE FUEL AND THE TRUCK IS WELL MAINTAINED. THE DEALERSHIP WANTS TO CHARGE UP TO $100 TO CLEAN THE CARBON OUT ONLY TO HAVE IT RETURN IN A MATTER OF MONTHS. I HAVE TALKED TO OTHERS THAT HAVE EXPERIENCED THE SAME CONDITION/PROBLEM. IN MY OPINION THIS CONDITION IS A TRUE SAFETY ISSUE. *JB
