2006 GMC ENVOY DENALI Fuel System, Gasoline Problems

AT EVERY FILLUP WE CAN SMELL GAS LIKE THERE IS A FUEL LEAK. I HAD A SHOP DO A FOG TEST AND THEY CONFIRMED A LEAK "SOMEWHERE FROM THE TOP OF THE TANK". THE TANK WOULD NEED TO BE DROPPED TO VISUALLY INSPECT AT A COST OF $400-$500 JUST FOR THE DROPPING OF THE TANK. THEN THERE WOULD BE ADDED COSTS TO REPAIR WHATEVER IS CAUSING THE LEAK AND SMELL OF GAS. AFTER HEARING THAT I CAME HOME TO START MY SEARCHING FOR RECALLS & SAFETY NOTICES TO FIND THAT GM HAD A NOTICE ISSUED AS WELL AS THE NHTSA, BUT IT SEEMS THEY CUT THE YEAR OFF AT 2004 & 120,000 MILES. ACCORDING TO THE THREAD BELOW, IT APPEARS THIS WAS EXTENDED TO VEHICLE UNDER 150,000 MILES WHICH WE ARE WELL UNDER, BUT WE DON'T HAVE A 2002-2004 MODEL. THREAD - HTTP://FORUMS.TRAILVOY.COM/SHOWTHREAD.PHP?T=22530 VIN - [XXX] A VIN SEARCH FOR THIS ENVOY DIDN'T BRING UP THE FUEL LEAK ISSUES, BUT WE CAN SMELL GAS & CONFIRMED A LEAK EXISTS ON THE TOP OF THE TANK SOMEWHERE. WAS THIS PROBLEM EVER REPORTED FOR NEWER MODELS YET? INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). *TR

WHILE DRIVING THE VEHICLE THE AIR WILL LET OUT OF THE SHOCKS, ALSO HAPPENS WHEN VEHICLE IS PARKED. SSOMETIMES AIR WILL NOT EVEN ELEVATE SHOCKS WHEN VEHICLE IS TURNED ON. ALSO RANDOMLY WHILE VEHICLE IS STARTED WHWTHER THE FUEL TANK IS FULL OR EMPTY OR INBETWEEN IT WILL GO FROM ACCURATE LEVEL TO EMPTY MARK ON FUEL GAUGE. *TR

FUEL GAUGE STAYS ON EMPTY AFTER FILLING THE GAS TANK. IT MAY ALTERNATE FROM FULL TO EMPTY INTERMITTENTLY. *TT

ABOUT THREE MONTHS AGO THE FUEL GAUGE, AFTER FILLING THE TANK, WOULD READ EMPTY FOR A PERIOD OF TIME. THEN THE GAUGE WOULD READ FULL, THEN IT WOULD GO BACK TO EMPTY. THIS WOULD CONTINUE FOR A SHORT PERIOD OF TIME AND EVENTUALLY THE CORRECT (I ASSUMED) LEVEL WOULD BE SHOWN UNTIL THE NEXT FILL UP. AS TIME HAS PASSED, IT TAKES LONGER FOR THE GAUGE TO FINALLY SETTLE DOWN AND READ NORMALLY. I HAVE NOW RECEIVED A LETTER FROM GMC STATING THEY ARE AWARE OF THE PROBLEM AND WILL PAY FOR HALF THE REPAIR COST. MY QUESTION IS THAT IF THIS IS A PREMATURE FAILURE, AS THE LETTER STATES, WHY GMC IS NOT RESPONSIBLE FOR 100% OF THE COST. THE LETTER ALSO STATES THAT THE FUEL LEVEL SHOWN MAY READ MORE THAN THE ACTUAL LEVEL. COULD LEAD TO RUNNING OUT OF FUEL ON THE INTERSTATE, GETTING IN AN ACCIDENT TRYING TO GET OFF THE ROAD, AND/OR INJECTOR DAMAGE. *TR

I BOUGHT A USED 2006 GMC ENVOY DENALI WITH 69,000 MILES IN JUNE 2010, BY JULY I WAS REPLACING THE AIR SHOCKS ON THE RIGHT SIDE OF THE VEHICLE. ON ABOUT 7/28/2011 ON THE BELTWAY WHERE THE SPEED LIMIT IS 65 I WAS IN THE FAR LEFT LANE APPROACHING A LEFT HAND EXIT WHEN MY CAR STALLED, I HAD RUN OUT OF GAS WITH NO INDICATION. I WAITED OVER AN HOUR FOR SOMEONE TO COME PUT GAS IN MY TRUCK IN ABOUT 100 DEGREE TEMPATURE. I LATER RAN OUT OF GAS ON A BACK ROAD COMING TO MY HOUSE AT NIGHT. AGAIN NO INDICATOR LIGHT CAME ON TO LET ME KNOW I WAS LOW ON GAS. NOW THE GAS GAUGE FLOATS BETWEEN FULL AND EMPTY CONTIONUSLY. THIS WAS A VERY DANGEROUS AND SCARY SITUATION BOTH TIMES. MY FLASHERS WERE ON THE WHOLE TIME AND I HAD TO CHANGE THE BATTERY. NOW THE AIR WILL NOT COME OUT OF THE VENTS ONLY THE FLOOR AND DEFROST. BUT THE MOST IMPORTANT THING IS THE GAS GAUGE, I COULD HAVE BEEN INVOLVED IN AN ACCIDENT BOTH TIMES. *KB

2006 ENVOY DENALI. CONSUMER WRITES STATES GAS NEEDLE STOPPED FUNCTIONING *TGW THE CONSUMER STATED THE GAS NEEDLE BEGAN TO FLUCTUATE IN THE BEGINNING AND SINCE THAT TIME, THE NEEDLE HAS BEEN STUCK ON EMPTY, AND THE ENGINE LIGHT ILLUMINATED AS A RESULT. IN MARCH OF 2009, WHEN THE CONSUMER STARED THE VEHICLE, IT SOUNDED AS IF THERE WAS SOMETHING METAL TUMBLING AROUND UNDER THE HOOD. UPON INSPECTION OF THE VEHICLE, IT WAS DETERMINED THE ENGINE NEEDED TO BE REPLACED. ON JUNE 10, 2010, THE VEHICLE WOULD NOT START AND HAD TO BE TOWED TO THE DEALER. AN INSPECTION REVEALED A STARTER WAS NEEDED. ALSO, AN ALIGNMENT WAS DONE AND THE REAR BRAKE LIGHT WAS REPLACED. ON JUNE 12, 2010, THE VEHICLE WOULD NOT COME OUT OF PARK. AFTER 25 MINUTES AND OVER 50 ATTEMPTS, IT FINALLY CAME OUT OF PARK. THE CONSUMER DROVE TO THE DEALER, BUT THEY WERE UNABLE TO FIND A PROBLEM. SEPTEMBER 2010, THE CONSUMER NOTICED THE REAR OF THE TRUCK WAS SITTING VERY LOW. THE REAR END AIR SUSPENSION NEEDED TO BE REPLACED. THE AIR CONDITION RANDOMLY WORKED. THERE WERE TIMES WHERE THE AIR WOULD JUST START BLOWING AND NO BUTTONS WERE PUSHED. ALSO, THE DEFROSTER STOPPED WORKING. THE CONSUMER CONTINUED TO EXPERIENCE PROBLEMS WITH THE VEHICLE NOT COMING OUT OF PARK. *JB

TL* THE CONTACT OWNS A 2006 GMC ENVOY DENALI. WHILE DRIVING APPROXIMATELY 35 MPH THE CONTACT NOTICED THE FUEL GAUGE DISPLAYED EMPTY. THE CONTACT PREVIOUSLY ADDED FUEL AND CONFIRMED THAT THE FUEL TANK WAS NOT EMPTY. THE VEHICLE WAS NOT TAKEN TO THE DEALER FOR DIAGNOSTIC TESTING. THE VEHICLE WAS NOT REPAIRED. THE APPROXIMATE FAILURE MILEAGE WAS 57,000.

FUEL SENSOR FAILURE IN THE GAS TANK. CAUSING THE FUEL TANK TO READ EMPTY WHEN FULL, CAUSING THE SUV TO STALL WHEN THE TANK IS FULL, CAUSING THE CHECK ENGINE LIGHT TO COME ONE. THIS IS A SAFETY ISSUE. *KB

FUEL GAUGE IS NOT WORKING PROPERLY ON MY VEHICLE. IT STAYS ON "E" WHEN THERE IS PLENTY OF GASOLINE IN THE CAR. THERE HAVE BEEN SEVERAL COMPLAINTS ABOUT THIS THAT I HAVE SEEN ON WEBSITES. OCCASIONALLY THE GAUGE WILL MOVE UP BUT THEN GO BACK TO "E". I WENT TO DEALER AND THEY SAID IT IS A BAD FUEL SENOR GAUGE WHICH IS IN THE GASOLINE TANK. SEEMS LIKE THIS IS A COMMON ISSUE AND COULD CAUSE OTHER PROBLEMS. THE FUEL GAUGE HAS BEEN LIKE THAT FOR OVER 6 MONTHS, AS THE COST WAS ASTRONOMICAL AND I BELIEVE THERE SHOULD BE A RECALL. ADDITIONALLY, RECENTLY MY OIL PRESSURE GAUGE HAS SHOWN THE MAX AMOUNT AND THEN LAST NIGHT IT WENT DOWN TO THE LOWEST AMOUNT ON THE INSTRUMENT PANEL. IT GOES BACK AND FORTH FROM HIGH TO LOW AND THE OIL PRESSURE LOW LIGHT COMES ON THE INSTRUMENT PANEL AND THEN GOES OFF. IT SAYS TO STOP ENGINE. THERE DOES NOT APPEAR TO BE ANYTHING PHYSICALLY WRONG WITH MY ENGINE AND I WILL BE TAKING IT TO THE DEALER TOMORROW TO CONFIRM THAT. I BELIEVE BOTH OF THESE ISSUES ARE CAUSED BY A FAULTY INSTRUMENT PANEL OR ELECTRICAL SYSTEM INCLUDED IN GM'S MODELS. I HAVE A FAMILY MEMBER WITH AN OLDER GMC SUV WITH SIMILAR ISSUES AND THEY ALSO HAD ISSUES WITH A GMC TRUCK THEY USED TO HAVE BUT GOT RID OF IT, DUE TO THE MALFUNCTIONS. SEEMS LIKE A VERY COMMON ISSUE THAT SHOULD BE RESOLVED BY GE. *TR

THE PROBLEM IS WITH MY 2006 GMC ENVOY DENALI EDITION. ABOUT JANUARY 1, 2011 I RECEIVED GAS AT A SHELL GAS STATION. AFTER RECEIVING FUEL THE FUEL GAUGE REMAINED AT E AND DID NOT G TO F SIGNALING A FUEL TANK. EVERY TIME I REFILL THE TANK THE GAS NEEDLE SWINGS BACK AND FORTH BETWEEN F AND E. AROUND HALF A TANK THE NEEDLE DROPS TO E. THE FUEL GAUGE IS NOT READING ACCURATELY AND HAS CAUSED THE TRUCK TO STALL ONCE WHILE DRIVING. THE CHECK ENGINE LIGHT IS CONSTANTLY ON. I HAVE NOT DONE ANY REPAIRS BECAUSE I'VE BEEN TOLD THE FUEL ASSEMBLY HAS TO BE REPLACED WHICH IS A COSTLY REPAIR. TO PREVENT THE TRUCK FROM RUNNING OUT OF GAS WHILE DRIVING I'VE BEEN MONITORING THE TRIP METER AND GOING BY THE GAS MILEAGE. *TR

I HAVE A 06 ENVOY DENALI IT STARTED WITH THE CHECK ENGINE LIGHT BEING ON, I WAS TOLD BY A MECHANIC THAT IT NEEDS TO BE REPROGRAMMED WHICH WORKED UNTIL I DROVE A FEW MILES THEN CAME ON AGAIN.. THEN MY FUEL INDICATOR STOP WORKING STAYS ON E WHEN I FUEL UP. NOW THE OTHER DAY I LOST POWER IN MY GAS PEDDLE(READ LOW PRESSURE) THEN THE CAR DIED. IT STARTED UP BUT DIDN'T HAVE ENOUGH POWER IN THE PEDDLE. WAITING FOR MECHANIC TO LOOK AT IT. *TR

I HAVE A 2006 ENVOY DENALI WITH 53000 MILES, ABOUT 4 WEEKS AGO, I WAS FILING UP WITH GAS, I ALWAYS FILL UP AT 1/2 TANK SINCE I PURCHASED IT IN 06. AFTER FILLING THE GAS GAGE WENT TO EMPTY, AND THEN WOULD GO TO FULL, THEN BACK TO EMPTY. IT DID THIS FOR ABOUT 5 MIN AND THEN WENT TO EMPTY. NOW THE GAGE DO NOT READ CORRECTLY AT ALL, I USE THE TRIP TO KEEP TRACK OF MY MILEAGE AS THE REMAINING MILES FUEL GAGE DOES NOT REGISTER EITHER..... *TR
