2003 GMC ENVOY Fuelpropulsion System Problems

Fuel indicator bounces from Empty to full in the matter of seconds while going down the road. Also, issues with mileage range reported as the fuel indicator is fluctuating.

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...

2 YEARS AGO THE MAINTENANCE REQUIRED LIGHT HAS BEEN ON, WHEN CHECKED BY 2-3 MECHANICS THEY SAID IT COULD BE THE GAS CAP. THAT DIDN'T REMEDY THE SITUATION, THE LIGHT STAYED ON, THEN RECENTLY THE FUEL GAUGE STARTED DROPPING TO EMPTY AFTER A LITTLE LESS THAN HALF A TANK WAS USED. THEN FILLING THE GAS TANK CAUSED IT TO OVERFLOW IF YOU FILL IT TO FULL. AS OF TODAY THE CAR WHEN SHIFTED INTO REVERSE, SOMETHING CAME LOOSE INSIDE THE SHIFTER, NOW IT IS STUCK IN NEUTRAL.

STRONG SMELL OF GAS AND LEAKING FROM TOP OF TANK.

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

CRACK IN FILLER NECK WHERE IT ATTACHES TO THE GAS TANK.

IT STARTED WITH ENGINE MISFIRING CAUSING ENGINE TO JOLT WHICH DAMAGED #4 COIL PACK SEAL TO FAILED ALLOWING WATER INTRUSION. IN 2008, THE GMC MECHANIC REPLACED ALL SIX COILS SEALS BUT IN 2013-PRESENT P0440 ENGINE CODE IS A LEAK IN THE EVAPORATIVE EMISSION (EVAP). LOOSE FUEL TANK FILLER CAP IS THE MOST COMMON CAUSE THAT TRIGGERS THE P0440 CODE. I FAILED A FEW SMOG CHECK SPENDING HUNDREDS OF THOUSANDS OF DOLLARS YET MY PROBLEM STILL EXISTENCE. I'VE CONTACTED THE BUREAU OF AUTOMOTIVE REPAIR BECAUSE PURRFECT AUTO IN FULLERTON,CA LIED ABOUT FIXING MY CAR. THE BAR MADE PURRFECT AUTO REPLACE THE GAS TANK AND GAS CAP YET THE ENGINE LIGHT IS STILL ON DISPLAYING CODE P0440. ITS BEEN 14 YEARS AND I'M STILL DEALING WITH THIS PROBLEM.

TL* THE CONTACT OWNS A 2003 GMC ENVOY. WHILE THE VEHICLE WAS IN THE GARAGE AND WHILE DRIVING, THE ODOR OF FUEL WAS PRESENT. THE VEHICLE WOULD ALSO SHUDDER AND HESITATE WHILE DRIVING. THE VEHICLE WAS TAKEN TO THE DEALER WHERE IT WAS DIAGNOSED THAT THE FUEL PUMP WAS FAULTY AND NEEDED TO BE REPLACED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS 145,000.

I SMELL GAS ALL THE TIME WHEN I AM DRIVING

WHERE THE TOP OF THE NESK OF THE FUEL TANK MEETS THE FUEL PUMP IT IS BROKEN WHERE THE 2 MEET. FUEL VAPORS, AS WELL AS ACTUAL FUEL LEAKING ON THE GROUND R BOTH PRESENT. STATIONARY , AS WELL AS, IN MOTION.

TL* THE CONTACT OWNS A 2003 GMC ENVOY. AFTER REFUELING THE VEHICLE, THERE WAS A STRONG FUEL ODOR PRESENT. THE CONTACT NOTICED THE FUEL TANK WAS LEAKING FUEL. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 120,000.

TL* THE CONTACT OWNS A 2003 GMC ENVOY. THE CONTACT STATED THAT THERE WAS AN ABNORMAL ODOR COMING FROM THE REAR OF THE VEHICLE. THE CONTACT INSPECTED THE REAR OF THE VEHICLE AND DISCOVERED THAT THE FUEL TANK WAS DAMP. THE VEHICLE WAS DRIVEN TO AN INDEPENDENT MECHANIC WHERE IT WAS DIAGNOSED THAT FUEL TANK SENDING UNIT HAD CORROSION AND NEEDED TO BE REPLACED. THE VEHICLE WAS REPAIRED.

I STARTED EXPERIENCING A STRONG SMELL OF GASOLINE WHILE DRIVING AND WHEN THE VEHICLES WAS SHUT DOWN. WHEN I FIRST NOTICED THE ODOR I COULD NOT SEE ANY VISIBLE LEAKS UNDER THE VEHICLE, AFTER ABOUT A WEEK I STARTED NOTICING DRIPS OF FUEL UNDER THE VEHICLE. I CRAWLED UNDER THE VEHICLE TO FIND THE LEAK AND NOTICED A VERY FINE SPRAY OF GASOLINE COMING FROM THE TOP OF THE TANK. I THEN DROPPED THE FUEL TANK AND NOTICED THAT TUBE FROM THE FUEL PUMP WAS CORRODED TO THE POINT THAT IT WAS SPRAYING GASOLINE WHILE UNDER PRESSURE. THE FUEL PUMP IS LOCATED IN A LOW POINT ON THE TOP OF THE TANK WHICH ALLOWS FOR ROAD DEBRIS/SALT AND WATER TO SIT AND ERODE THESE TUBES ON THE TOP OF THE FUEL PUMP. THIS IS A VERY DANGEROUS PROBLEM AS ALL IT WOULD TAKE IS ANY FORM OF IGNITION TO CAUSE...

TL* THE CONTACT OWNS A 2003 GMC ENVOY. THE CONTACT STATED THAT AN ODOR OF GASOLINE FUEL WAS PRESENT INSIDE AND OUTSIDE OF THE VEHICLE. THE CONTACT INSPECTED THE VEHICLE AND DISCOVERED A FUEL LEAK FROM THE TOP DRIVER'S SIDE OF THE FUEL TANK. THE CONTACT INDICATED THAT THE FUEL LEAK ONLY OCCURRED WHEN THE ENGINE WAS POWERED ON. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS 73,000.

MY CAR IS REAPING WITH THE SMELL OF GAS ON THE INSIDE AND OUTSIDE OF THE CAR. I CALLED GM CUSTOMER CARE CENTER ABOUT THIS PROBLEM BEING HAZARDOUS AND ALL THEY OFFERED WAS A $150 VOUCHER AVAILABLE AT THE GMC DEALERSHIP. I AM CONFUSED AS TO WHY 2006/2007 MODELS WERE RECALLED FOR THIS MATTER AND THE 2003 MODEL WAS NOT RECALLED. I AM AFRAID TO DRIVE THIS CAR BECAUSE I BELIEVE IT WILL EXPLODE! *TR

SOME TIMES WHEN THE BRAKES ARE APPLIED THE THROTTLE ALSO ADVANCES CAUSING UNWANTED ACCELERATION. HAPPENS AT LOW SPEEDS. HAVE THERE BEEN ANY FACTORY RECALLS FOR THIS PROBLEM? *TR

TL* THE CONTACT OWNS A 2003 GMC ENVOY. THE CONTACT STATED THAT AFTER REFUELING, THE FUEL GAUGE WOULD READ EMPTY. THE VEHICLE WAS NOT INSPECTED BY A DEALER OR AN INDEPENDENT MECHANIC. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOT CONTACTED. THE FAILURE MILEAGE WAS APPROXIMATELY 90,000. THE CURRENT MILEAGE WAS APPROXIMATELY 100,000. *TR

I FILLED THE GAS TANK WITH GAS, AND WHEN I WAS DRIVING, I GOT THIS SMELL OF GASOLINE. AND WHEN I GOT OUT TO CHECK THE VEHICLE, I SAW THAT THE INLET CHECK VALVE (ICV) WAS FRACTURED. AND IT WAS LEAKING GASOLINE.AND 2 OR 3 DAYS AFTER I HAD THE CHECK ENGINE LIGHT ON, WITH THE CODE P0442. *TR

NOTICED STRONG FUEL ODOR COMING FROM VEHICLE. UPON DIAGNOSIS AT THIRD PARTY SERVICE PROVIDER, WAS INFORMED OF LEAK AT FUEL TANK. KNOWN ISSUE PER GM BULLETIN 07076, BUT WAS INFORMED BY GM THAT VEHICLE MILEAGE EXCEEDS COVERAGE PARAMETERS PER GM REF#[XXX]. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). *TR

TL* THE CONTACT OWNS A 2003 GMC ENVOY. THE CONTACT STATED WHILE EXITING THE VEHICLE HE NOTICED THE SMELL OF FUEL BEING EMITTED. UPON INSPECTION IT WAS FOUND THAT FUEL WAS LEAKING FROM THE VEHICLE. THE VEHICLE WAS TAKEN TO A DEALER WHERE IT WAS FOUND THAT THE GAS TANK HAD FAILED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS CONTACTED ABOUT THE ISSUE. THE FAILURE MILEAGE WAS 133,120 AND THE CURRENT MILEAGE WAS 133,465. THE VIN WAS NOT AVAILABLE.

THE CAR STARTING LEAKING GAS AND I WAS AFRAID IT WOULD START A FIRE. I FOUND OUT THAT THE GAS TANK FILLER NECK WAS CRACKED. REPLACEMENT COST WAS $1,220.68. GMC SAID THAT THIS WAS NOT A RECALL ITEM FOR MY CAR BUT THERE WERE RECALLS FOR THE SAME PROBLEM FOR THE ENVOY XL. *TR

I HAVE A 03 ENVOY SXL THAT SMELLED LIKE GAS, THE DEALER STATED THERE WAS A CRACK IN THE HOSE. I HAD THAT REPLACED AND NOW IT LEAKS GAS GOING DOWNHILL. AS I SAW OTHERS ARE HAVING THE SAME ISSUES AND MOST IF NOT ALL THAT HAS SUV'S HAVE CHILDREN. IF THE SAME MODEL PART WAS RECALLED ON THE TRAILBLAZER WHY NOT ENVOY'S? GMC SHOULD RECALL ALL CARS THAT HAS THE MODEL NUMBER TO FIX THE PROBLEM BEFORE THEY GO UP IN FLAMES WITH OUR CHILDREN. *TR
