TL* THE CONTACT OWNS A 2002 GMC ENVOY. THE CONTACT STATED THAT WHILE OPERATING THE VEHICLE, AN ODOR OF FUEL WAS PRESENT INSIDE AND OUTSIDE OF THE VEHICLE. ALSO AT TIMES, FUEL WAS SEEN ON THE PAVEMENT UNDERNEATH THE VEHICLE. THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC WHO DIAGNOSED THE VEHICLE AND STATED THAT THE FUEL PUMP CONNECTION LINE WAS DEFECTIVE AND NEEDED TO BE REPLACED. THE VEHICLE WAS NOT YET REPAIRED. THE LOCAL DEALER AND MANUFACTURER WERE NOT NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS 173,000. INVALID VIN.

I SMELLED A STRONG ODOR OF GASOLINE WHILE THE VEHICLE WAS PARKED OUTSIDE MY RESIDENCE. PERFORMED A WALK AROUND INSPECTION AND FOUND NO VISIBLE SIGNS OF FUEL LEAKAGE. OPENED THE HOOD AND HAD NO VISIBLE SIGNS OF LEAKAGE. ENVOY IS HARD TO START BUT ONCE STARTED CONTINUES TO RUN WITH NO ISSUES. GASOLINE FUMES ARE EVIDENT IN THE CAB WHILE PARKED BUT DISPERSE WHEN MOVING DOWN THE ROAD. UPON STOPPING IN TRAFFIC, FUMES IMMEDIATELY BECOME VERY STRONG IN THE CAB. RESEARCHING ON LINE SIMILAR SITUATIONS, IT APPEARS THAT THERE IS A PROBLEM ON TOP OF THE GAS TANK. CHECKED UNDER THE ENVOY AND NOTICED SOME MINOR STREAKING ON THE TANK. I HAVE STOPPED DRIVING THE VEHICLE UNTIL I CAN GET THE VEHICLE REPAIRED. ASSUMING IT IS THE SAME FUEL PUMP EROSION ISSUE, THE ESTIMATED COST TO REPAIR IS BETWEEN $650 AND $900. MA 10/6 THE CONSUMER STATED AFTER REMOVING THE GAS TANK, HE ATTEMPTED TO REMOVE THE FUEL LINES FROM THE FUEL PUMP. THE METAL LINES BROKE OFF AT THE TOP OF THE FUEL PUMP AS HE ATTEMPTED TO REMOVE THE CLIPS HOLDING THE LINES ON TO THE FUEL PUMP. THE TOP OF THE FUEL PUMP AND THE ASSOCIATED METAL LINE WERE RUSTED BEYOND REPAIR. IT APPEARED THE METAL LINES AS PART OF THE FUEL PUMP WERE SPRAYING FUEL ON THE TOP OF THE FUEL TANK WHEN THE PUMP WAS RUNNING. THE DESIGN OF THE TOP OF THE TANK WITH THE FUEL PUMP PROVIDED A BOWL ON THE TOP OF THE TANK WHERE THE FUEL PUMP WAS LOCATED ALLOWING SALT WATER TO POOL ON TOP OF THE TANK DURING THE WINTER DRIVING SEASON. THE FUEL PUMP WAS REPLACED AND THE TANK WAS RE-INSTALLED. UPDATED 03/01/16.*JB

IT LIKE IT NOT GETING ANY GAS WHEN I HIT THE GAS IN BOGGS DOWN LET OFF OTS FINE PCM IM GUESS. *TR

IN FEBRUARY OF 2012 I BEGAN TO NOTICE A VERY LARGE ODOR OF GASOLINE COMING FROM THE REAR OF THE VEHICLE. I HAVE OWNED THIS CAR SINCE SEPTEMBER OF 2009 AND THIS HAS JUST BECOME AND ISSUE. LOOKED UP VEHICLE RECALLS AND CAME ACROSS THIS. SUMMARY: ON CERTAIN SPORT UTILITY VEHICLES, A FUEL FILTER FITTING CAN BECOME DISCONNECTED. IF THIS WERE TO OCCUR WHILE ATTEMPTING TO START THE ENGINE, A NO-START CONDITION WOULD RESULT AND FUEL WOULD BE PUMPED OUT THE FUEL FILTER ONTO THE GROUND. CONSEQUENCE: IF THE FITTING BECOMES DISCONNECTED WHILE THE VEHICLE IS IN MOTION, THE ENGINE WOULD STOP DUE TO INADEQUATE FUEL SUPPLY AND CAUSE A LOSS OF POWER STEERING ASSIST. IF AN IGNITION SOURCE WERE PRESENT, FUEL LEAKAGE FROM A DISCONNECTED FUEL FILTER FITTING COULD RESULT IN A FIRE. ACTIONS: DEALERS WILL REPLACE THE FUEL FILTER QUICK CONNECT RETAINERS. OWNER NOTIFICATION BEGAN SEPTEMBER 20, 2002. OWNERS WHO TAKE THEIR VEHICLES TO AN AUTHORIZED DEALER ON AN AGREED UPON SERVICE DATE AND DO NOT RECEIVE THE FREE REMEDY WITHIN A REASONABLE TIME SHOULD CONTACT CHEVROLET AT 1-800-222-1020. GMC AT 1-800-462-8782, OR OLDSMOBILE AT 1-800-442-6537. FOR DETAILED INFORMATION & SUPPORTING DOCUMENTS, SEE THE OFFICIAL NHTSA PAGE CONCERNING RECALL #02V121000 GM SAID MY CAR WAS NOT ELIGABLE FOR REPAIR.

2002 GMC ENVOY - CONTINUE TO EXPERIENCE FUEL SMELL CONDITION. HAD VEHICLE SERVICED IN 2009 FOR THIS ISSUE.

GAS SMELL BOTH IN AND OUT OF VEHICLE. WITHIN A COUPLE OF DAYS GAS WOULD LEAK AFTER CAR WAS DRIVEN. FUEL PUMP LEAKED DUE TO RUSTED PIPE ON FUEL PUMP TO FUEL LINE. IT IS THE ONLY EXPOSED STEEL FITTING AND SITS ON TOP OF THE GAS TANK WHERE WATER AND MOISTURE CAN COLLECT, WHICH IS THEN CONDUCIVE TO RUSTING. *TR

LEAKING FUEL PUMP ASSEMBLY IN TANK. *AK

2002 GMC ENVOY FUEL SMELL. TOOK TO 2 DIFFERENT GM DEALERS BEFORE PROBLEM WAS FOUND. THE 2ND GM DEALER FOUND IT TO BE THE FUEL PUMP MODULE WHICH WAS RUSTED AND LEAKING GAS. GM WOULD NOT STAND BEHIND THIS PROBLEM AS SHE WAS THE SECOND OWNER. THE PROBLEM IS THE WAY METAL FUEL PUMP MODULE SITS IN THE RECESSED PORTION MIDDLE OF THE PLASTIC FUEL TANK INVITES MOISTURE, RUST , SALT, CORROSION ETC. REPLACED AT OUR EXPENSE OF $520.00 THIS IS A DESIGN PROBLEM. *JB

CRACK IN GAS TANK ON GMC ENVOY THAT WAS FOUR MONTHS OLD.

WHEN ATTEMPTING TO FILL THE FUEL TANK, GASOLINE WILL SPILL OUT THE TOP OF THE TANK (NOT THE FILLER HOSE) AND ONTO THE GROUND. RATHER THAN RETURN UP THE HOSE AND INDICATE TO THE PUMP THAT THE TANK IS FULL, THE GASOLINE GOES EVERYWHERE. IF YOU JUST ADD GAS BUT DO NOT FILL THE TANK, THIS DOES NOT HAPPEN.*AK

THE ELECTRICAL COMPUTER MEMORY FOR THE EXTERIOR MIRRORS AND THE SEAT ADJUSTER FAILED. THIS CAUSED THE SEATS FOR DRIVER AND PASSENGER SIDE NOT TO BE ADJUSTED. ALSO THE MIRRORS ARE NOT ABLE TO BE ADJUSTED. DRIVER HAS TO CONTINOUSLY ADJUST THE MIIRRORS IN ORDER TO SEE. DEALER RESET MEMORY SEATS, REPROGRAMMED MIRROR MEMORY, AND REPLACED LEFT AND RIGHT FRONT SEAT MODULES. DID NOT REMEDY PROBLEM. CUSTOMER STATES THAT THERE IS A FUEL LEAK LOSS OF 1/2 TANK IN 3 MILES. DEALER REPAIRED LOOSE CONNECTION BETWEEN MAIN FUEL LINE AND THE FUEL TANK. *TT

WHILE WAITING AT A STOP LIGHT FUEL TANK LOST ALL IT'S FUEL DUE TO A HOSE SEPARATING FROM THE TANK.

WE PURCHASED NEW VEHICLE OCTOBER 2001 AND WITHIN 4 MONTHS BEGAN EXPERIENCING PROBLEMS BEGINNING WITH A NOISE WITHIN THE STEERING WHEEL. DEALER TECHNICIAN REPLACED DEFECTIVE AIRBAG MODULE. THE NEXT MONTH, MY NEW ENVOY HAS BEEN TO THE DEALER 4 TIMES FOR THE SAME PROBLEM OF 1) WIND AND/OR WHISTLING NOISE AT SPEEDS ABOVE 45MPH, 2) "VIBRATION" NOISE COMING FROM TRANSMISSION WHEN VEHICLE REACHES 3RD GEAR , 3) WHEN VEHICLE HAS REACHED 3RD GEAR AND PREVIOUS NOISE BEGINS, THERE IS ALSO A VIBRATION FELT IN THE ACCELERATION PEDAL. ON THE FIRST TRIP TO DEALER FOR THESE PROBLEMS, TECHNICIAN ONLY AGREED WITH THE WIND NOISE. DISCOVERED THE FRONT SIDE MIRRORS WERE THE CAUSE. REPLACED BOTH MIRRORS---PROBLEM STILL EXISTS, HOWEVER, HE CAN'T HEAR THEM. EXPLAINED IT WAS THE NATURE OF THE VEHICLE. HE ALSO REPAIRED THE WEATHERSTRIPPING WHICH HAD "FALLEN OFF" THE RIGHT REAR DOOR. HE ADVISED THAT HE DID NOT HEAR ANY NOISE IN THE TRANSMISSION AREA OR IN THE GAS PEDAL. WE TOOK TO ANOTHER DEALER WHO HAD A TECHNICIAN TEST DRIVE THE VEHICLE AND ADVISED THAT THERE WAS BOTH A NOISE IN THE AREA OF TRANSMISSION AND A VIBRATION IN THE GAS PEDAL. RETURNED TO THE DEALER WHO ORIGINALLY WAS DOING REPAIR WORK AND HAD HIM RIDE WITH ME. AT THIS TIME, HE HEARD THE NOISE I WAS COMPLAINING ABOUT AND ADVISED THAT IT WAS COMING FROM THE HEAT SHIELD AT THE CATALYTIC CONVERTER. MADE AN APPOINTMENT FOR REPAIRS, PICKED UP THE VEHICLE AND LATER THE SAME DAY, THE NOISE RETURNED. TOOK VEHICLE BACK, TECHNICIAN SAID HE DIDN'T HEAR ANY MORE NOISES. WAITED 2 WEEKS, MADE ANOTHER APPOINTMENT TO RETURN VEHICLE FOR RIGHT REAR DOOR "RATTLING" , AND "HEAT SHIELD" NOISE WHICH HAD BECOME NON STOP. AT THIS TIME, THEY REPLACED THE WEATHERSTRIPPING ON THE DOOR AND AGAIN ADJUSTED HEAT SHIELD BY MAKING A "CUSHION" SO THAT IT WOULD NOT VIBRATE AGAINST THE EXHAUST MANIFOLD. THIS DID NOT RESOLVE THE PROBLEM, AS IT STILL "VIBRATES" SO AS I CAN STILL FEEL STRESS THROUGH THE GAS PEDAL ON THE TRANSMISSION WHEN REACHING SPEED.*

GAS GAUGE WAS 1/4 TANK OFF, RETURNED TO DEALER TO FIX PROBLEM AFTER RUNNING OUT OF GAS. DEALER REPLACED FLOAT/SENDER. RETURNED TO DEALER ONE HOUR LATER AFTER ATTEMPTING TO FILL TANK WITH FUEL AND FUEL POURED OUT OF TOP OF TANK. DEALER THEN CLAIMED THE FUEL TANK WAS DEFECTIVE AND DISTORTED BY THE FACTORY, ORDERED NEW TANK, REPLACED SAME. ALL IS WORKING NOW.*AKI
