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.

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.

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.

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.

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 AN UNCONTROLLABLE FIRE. GM SHOULD BE REQUIRED TO REPAIR THIS UNDER A MANDATED RECALL DUE TO THE SEVERITY OF THIS PROBLEM. *TR

SMELLING OF GAS AND LEAKING ON GROUND, AS I'M READING THIS IS A COMMON PROBLEM WHICH IS VERY SERIOUS. I REALLY THINK GM NEEDS TO INCLUDE THIS 2003 GMC ENVOY AS PART OF THEIR RECALL AS WELL. THIS HAS BEEN GOING ON FOR YEARS IT LOOKS LIKE AND NOTHING HAS BEEN RECALLED. GUESS HUMAN LIFE IS NOT IMPORTANT.GM NEEDS TO RECALL THIS PROBLEM ASAP BEFORE SOMEONE GETS HURT. *TR
