2006 GMC Envoy Denali Fuel system Problems

MY HUSBAND AND I WERE TRAVELING WHEN THE VEHICLE SHUT OFF WITH NO WARNING AT ALL AND ALL THE DASH BOARD LIGHTS CAME ON. THE VEHICLE WOULD NOT RESTART BUT WOULD TURN. THIS HAPPENED SATURDAY 9/2/17 ON A COUNTRY HIGHWAY OUT IN NOWHERE . WE CALLED A TOW TRUCK. THANK GOD FOR CELLPHONES. ON 11/12/2016 HUB BEARINGS REPLACED. 11/15/16 MODULE AND CONNECTOR REPLACED AND FUEL LEVEL SENSORS AND RING REPLACED. THREE YEARS AGO A/C WENT OUT. REPLACED.

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

INITIALLY, WHEN THE CAR WAS FILLED WITH FUEL, THE FUEL GAUGE WOULD AUTOMATICALLY GO TO EMPTY AND THE ENGINE LIGHT WOULD COME ON. AFTER DRIVING SEVERAL MILES, THE GAUGE WOULD CORRECT ITSELF AND THE ENGINE LIGHT WOULD GO OFF. AFTER MONTHS OF THIS, THE SYSTEM DOES NOT CORRECT ITSELF AND I NEVER KNOW HOW MUCH GAS I HAVE - IT CONSTANTLY GOES FROM FULL TO EMPTY.

INITIALLY, WHEN THE CAR WAS FILLED WITH FUEL, IT IMMEDIATELY INDICATED THAT THE CAR WAS EMPTY AND THE ENGINE LIGHT CAME ON. ONCE YOU USED A COUPLE OF GALLONS THE FUEL GAUGE BEGAN WORKING AND THE ENGINE LIGHT WENT OFF. JUST RECENTLY THE SYSTEM IS NOT CORRECTING ITSELF AND THE FUEL GAUGE WILL CONSTANTLY GO BETWEEN FULL AND EMPTY SO I NEVER KNOW HOW MUCH FUEL I HAVE IN IT. ALSO THE ENGINE LIGHT IS REMAINING 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

1. STARTED WITH HORN HONKING ON ITS OWN, RADIO TURNING ON AND OFF AND HEATING AND COOLING TURNING ON AND OFF AND BATTERY BEING DRAINED. DEALER REPLACED 2 BATTERIES. 2. STABILITRAK WARNING LIGHT WOULD INTERMITTENTLY COME ON AND SAY IT NEEDED SERVICED. 3. GAS GAUGE STARTED MALFUNCTIONING AFTER A FILL UP. NEEDLE WOULD FLUCTUATE AND EVENTUALLY REMAIN ON E. WAS TOLD BY DEALER IT WAS EITHER THE FUEL LEVEL SENSOR OR INSTRUMENT PANEL. 4. VEHICLE STARTED TO JERK FORWARD WHEN SITTING AT STOP LIGHT. JERKS ARE STRONG ENOUGH THAT YOU FEEL LIKE YOU WERE REAR ENDED. THEN STARTED NOTICING THE JERKS WHILE DRIVING AT HIGHWAY SPEED. 5. OIL GAUGE BEGAN FLUCTUATING FROM HIGH TO LOW. WAS AGAIN TOLD IT WAS A BAD INSTRUMENT PANEL .6. REAR AIR SUSPENSION BEGAN DEFLATING WHEN VEHICLE WOULD SIT FOR LONG PERIODS OF TIME. LOW ENOUGH THAT TIRES ALMOST TOUCH TOP OF WHEEL WELL. COMPRESSOR WOULD COME ON AND REAR END WOULD COME BACK UP TO NORMAL. NOW IT DEFLATES OVER SHORT PERIODS OF TIME AND TAKES A CONSIDERABLY LONGER AMOUNT OF TIME TO REINFLATE. I AM NOW NOTICING THAT IT IS DEFLATING SOME WHILE DRIVING. IF YOU HIT A BUMP YOU CAN FEEL THE TIRE HIT THE TOP OF WHEEL WELL. DEALER COULD NOT EXPLAIN THE JERKING. WAS TOLD THERE WAS PROBABLY AN ELECTRICAL PROBLEM CAUSING THINGS TO COME ON AND OFF. FUEL GAUGE IS BEING REPLACED FREE AS A DEFECTIVE PART. WAS TOLD REAR SUSPENSION WAS MOST LIKELY A DEAD COMPRESSOR AND TIRES COULD POSSIBLY RUB OR BLOW OUT IF SUSPENSION DEFLATES WHILE DRIVING. *TR

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

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

FUEL LEVEL SENSOR FAILED AT JUST OVER 52,000. MILES. FROM MY RESEARCH THIS SEEMS TO BE A RECURRING PROBLEM WITH MANY 2006 GMC OR CHEVROLET VEHICLES FROM THE SAME YEAR RANGE 2005 TO 2006. THE RECOMMENDATION FROM THE DEALERSHIP WAS "IF YOU DON'T WANT TO PAY THE $500.00 PLUS REPAIR ESTIMATE, JUST DO WHAT MANY OTHER PEOPLE ARE DOING AND RESET YOUR TRIP METER AT EVERY FILL UP. LOOK TO RE-FUEL BETWEEN 250 AND 300 MILES." IN MY RESEARCH I DISCOVERED A PERSON WHOSE VEHICLE DID THE SAME EXACT THING. HE WAS USING THE TRIP METER AS THE GAUGE AND EVEN WITH FUEL IN THE VEHICLE, HE WAS LEFT STRANDED IN AN INTERSTATE DUE TO AN ENTIRE FUEL SYSTEM FAILURE. SHOULD THIS HAPPEN TO A FAMILY DURING INCLEMENT WEATHER THERE COULD BE SERIOUS SAFETY SITUATIONS. IN LIGHT OF THE FACT THAT THE VEHICLE THAT WE OWN WAS PRICED AT $38,000.00 PLUS MSRP,I WOULD EXPECT THAT THE FUEL SENDING UNIT WOULD PERFORM BEYOND THE 50,000 MILE RANGE. I'M SURE, BY NOW, THAT YOUR ORGANIZATION HAS HEARD FROM OTHER GM OWNERS ABOUT THIS SAME SITUATION. I AM INTERESTED IN YOUR RESPONSE. *TR
