2003 GMC Envoy Fuel System Problems

CHECK ENGINE LIGHT STAYS ON. HAD A DIAGNOSTIC DONE AND THEY SAID THERE'S A GAS LEAK COMING FROM THE GAS TANK FUEL INLET VALVE. COMMON PROBLEM FOR THE GMC ENVOY AND CORRECTION INVOLVES REPLACING THE WHOLE FUEL TANK COSTING AN AVERAGE $1,400. DANGEROUS TO DRIVE IF LEFT UNTREATED. CALLED GMC CORPORATE AND I DIDN'T GET ANY HELP. THEY SAID MY ENVOY WAS NOT UNDER ANY RECALLS. THEY SHOULD BE HELD RESPONSIBLE FOR THIS DEFECT.

U GUYS ISSUED RECALLED ALL GMC VEHICLES FOR A LEAKING GAS CK VALVE ON GAS TANK NO MATTER HOW LONG IN SERVICE STATIONARY OR ON MOTION CK WITH MY LOCAL DEALER KARL CHEVROLET ANKENY IOWA THEY SAY EXPIRED I'M 2017 AT 150000 YOUR RECALLED AS LONG AS IN SERVICE. *TR

THE FUEL FILL LINE IS BROKEN FROM THE GAS TANK. I WAS FILLING THE TANK FOR HOLIDAY TRAVEL AND THE THE TANK BEGAN TO LEAK. EVERY TANK THAT IS ORDERED BY THE REPAIR SHOP IS DAMAGED IN THE SAME PLACE

BULLETIN NO.:14423 DATE: NOVEMBER 2015 PART NUMBER: 15077622 TANK, FUEL (18.7 GAL.) THE ICV IS LOCATED ABOVE THE FULL FUEL LEVEL. A FRACTURED ICV COULD ALLOW FUEL VAPORS TO PASS THROUGH AND DROPLETS OF FUEL TO ACCUMULATE ON THE SIDE OF THE FUEL TANK AS IT PASSES OVER THE FRACTURE DURING REFUELING. IF THE ICV FRACTURES, THE VEHICLE'S SERVICE ENGINE SOON (SES) LIGHT MAY ILLUMINATE, AND YOU MAY NOTICE A FUEL ODOR AND/OR A FEW DROPS OF FUEL ON THE GROUND WHEN REFUELING THE VEHICLE. THIS HAS HAPPEN TO ME AND NOW MY TANK NEEDS TO BE REPLACED. THIS IS A KNOWN ISSUE WITH GMC ENVOY REGARDLESS OF YEAR OR HOW LONG THEY ARE IN SERVICE. THE COMPANY NEEDS TO BE HELD ACCOUNTABLE FOR POOR QUALITY OF PARTS ESPECIALLY WHEN IT IS A SAFETY CONCERN AND HAZARD WITH FUEL ODOR COMING INTO THE CAB OF THE VEHICLE AND SPILLING OUT WHEN GOING UP A HILL. BEING TOLD TO ONLY FILL MY GAS TANK UP HALF TO THREE QUARTERS FULL DUE TO THAT PART BEING BROKEN IS THE WRONG ANSWER. IN MOTION WHEN I SMELL GAS AND THEN NOTICE IT WHEN I FILL THE VEHICLE UP AND IT STARTED POURING OUT.

STRONG SMELL OF GAS AND LEAKING FROM TOP OF TANK.

WHEN IN PARK POSITION HEAVY GAS FUMES COMING FROM A LEAK AT THE TOP OF THE TANK. YOU CAN VISUALLY SEE THE GAS STAINS ON THE SIDES AND BOTTOM OF TANK.WHEN ROLLING TO A STOP THE FUMES RETURN.I'M GETTING HEADACHES AND BURNING OF MY EYES AND THROAT.I CHECKED MY VIN FOR RECALLS, THE PARTS INVOLVED ARE #14423C FUEL TANK INLET CHECK VALVE FRACTURE,AND #07076A FUEL TANK MODULAR RESERVOIR ASSEMBLY CORROSION #12166 FUEL FILLER NECK..I'M AFRAID EVERY TIME I DRIVE IT THAT I COULD BE BODILY HARMED AT ANY GIVEN MOMENT, A SPARK,SOMEONE FLICKING A CIGARETTE,A ACCIDENT, ANYTHING THAT WOULD TRIGGER A SPARK.

LEAKING FUEL ON TANK AT FUEL NECK...FUEL FUMES, FUEL ON GROUND MAY CAUSE FIRE, NOT ENVIRONMENTALLY SAFE AS FUEL IS DUMPING ON THE GROUND WHERE EVER YOU DRIVE

GMC IS ADMITTING TO A FAULTY GAS TANK AND ONLY COVERS THIS UP TO 150,000 MILES I BOUGHT THE CAR AFTER THE 150,000 MILES AND NOW HAVE GAS LEAKING THE TANK WAS NEVER FIXED. WHY DOES THE MILEAGE MAKE A DIFFERENCE? THIS IS A MAJOR SAFETY ISSUE THAT GMC SHOULD COVER REGARDLESS OF THE MILEAGE. JUST BECAUSE MY GAS TANK DID NOT LEAK AS SOON AS OTHER ONES DID MEANS I SHOULD NOT BE COVERED? A RECALL IS A RECALL AND THEY SHOULD BE RESPONSIBLE FOR FIXING THE PROBLEM.

THIS IS ALL OVER THE INTERNET. PLASTIC GAS TANK LEAKS. GMC DOES NOT CARE. I TALKED WITH THEM THEY IGNORE REPAIR IS $1,600.00 OR MORE. PEOPLE ARE FIXING WITH GLUE? GASOLINE SPILL FROM CRACKED PLASTIC FUEL TANK.

FUEL PUMP MODULE CORROSION CAUSING LEAKING FUEL AND FUEL VAPORS FROM THE TOP OF THE FUEL TANK. THIS IS DUE TO A DESIGN DEFECT AS THE FUEL PUMP MODULE SITS LOWER THAN THE HIGHEST POINT OF THE FUEL TANK AND MOISTURE AND DEBRIS ACCUMULATE ON TOP OF THE FUEL PUMP MODULE. THE TOP OF THE MODULE IS NOT MANUFACTURED WITH APPROPRIATE RUST-PROOFING MEASURES AND THE MATERIALS USED LEAVE IT PRONE TO RUSTING AND FAILURE, COMPROMISING THE SEAL AND ALLOWING FUEL TO ESCAPE FROM THE TANK. THIS POSES A FIRE HAZARD, ESPECIALLY IF FUEL IS ABLE TO REACH HEATED EXHAUST PIPES, ETC. I TOOK MY VEHICLE INTO A A GMC DEALERSHIP AND WAS DENIED REPAIR OF THE VEHICLE OR REIMBURSEMENT FOR REPAIR. THERE WAS A SPECIAL COVERAGE FOR THIS VEHICLE THAT HAS SINCE EXPIRED, PROVING THAT GM IS / WAS AWARE OF THE PROBLEM. GIVEN THE NUMEROUS COMPLAINTS OF THIS EXACT SAME ISSUE, THIS SHOULD BE ESCALATED TO RECALL STATUS DUE TO THE INHERENT SAFETY ISSUE AND FIRE RISK.

THE FUEL INLET SEAL ON THE TOP OF THE FUEL TANK HAD SEPARATED CAUSING A SMELL OF FUEL AND ALLOWING MATTER TO ENTER THE FUEL TANK FROM THE TOP...POSSIBLY CAUSING THE PREMATURE FAILING OF THE FUEL PUMP. WE UNDERSTAND GMC HAS EXTENDED THE WARRANTY ON THE VEHICLE FOR THIS ISSUE TO 150,000 MILES. OUR VEHICLE HAD OVER 155,000 MILES WHEN THE PROBLEM OCCURED BUT WE NEVER RECEIVED NOTIFICATION FROM GMC OF THE EXTENDED WARRANTY. HAD WE RECEIVED THIS NOTIFICATION WE WOULD HAVE TAKEN IN THE VEHICLE FOR AN IMMEDIATE REPAIR. THE FUEL PUMP FAILED AND WE HAD TO PURCHASE A NEW FUEL TANK (AS A RESULT OF THE FAULTY TOP SEAL) AND FUEL PUMP...COSTING US ALMOST $1,700. WE HAVE A COPY OF THE REPAIR BILL BUT I AM UNABLE TO SCAN AND UPLOAD IT HERE AT THIS TIME... I AM IN THE MILITARY AND WILL BE MOVING TO KOREA IN APRIL, 2016
