2006 GMC ENVOY DENALI XL Complaints

WITH NO ADVANCE WARNING, THE FUEL GAUGE STARTED READING EMPTY IMMEDIATELY WHEN TANK WAS FILLED. POSSIBLY RELATED OR NOT, THE FLAP IN THE FUEL FILLER NECK DISAPPEARED ABOUT THE SAME TIME THE PROBLEM STARTED. ONCE THE PROBLEM BEGAN, THE FUEL LIGHT WOULD COME ON WHEN THE CAR WAS STARTED AND WOULD STAY ON CONSTANTLY. THE CHECK ENGINE LIGHT IS ALWAYS ON AS WELL. AS FUEL LEVEL DECREASED SOMETIMES THE GAUGE WOULD APPARENTLY READ CORRECTLY (E.G. BELOW 3/4 TANK). STOPPING OR STARTING SOMETIMES CAUSED THE GAUGE TO FLUCTUATE; OFTEN THE GAUGE GOES UP AND DOWN SEVERAL TIMES A MINUTE. OVER THE LAST EIGHT MONTHS THE CONDITION HAS WORSENED AND THE GAUGE OFTEN READS EMPTY, WITH OCCASIONAL SWINGS UP TO APPROXIMATELY CORRECT LEVEL (ESTIMATE BASED ON MILES DRIVEN SINCE FILLING TANK). HOWEVER, THE GAUGE NEVER WENT BELOW 1/8 TANK, EVEN THOUGH IT WAS LESS THAN TWO GALLONS FROM EMPTY IN A 24-GALLON TANK. *TR

I AM THE OWNER OF THE GMC ENVOY DENALI, 2006 MODEL VEHICLE. THE GAS TANK SENSOR AFTER A FILLUP BEGAN TO MALFUNCTION. SPECIFICALLY, THE TANK WAS FILLED, HOWEVER, THE GAS TANK FILL INDICATOR REMAINED ON EMPTY. THE FAILURE OF THE SENSOR HAS CAUSED THE "CHECK ENGINE" LIGHT TO COME ON AND REMAIN ON. *TR

ON MAY 10, 2011 THE REAR SPOILER (WITH THIRD BRAKE LIGHT) FLEW OFF THE BACK OF MY 2006 GMC ENVOY DENALI XL SHORTLY AFTER ENTERING THE HIGHWAY. LUCKY FOR ME IT WAS CRUSHED BY A PASSING TRACTOR TRAILER INSTEAD OF HITTING SOMEONE'S WINDSHIELD. GMC SAID THAT SINCE MY SUV WAS 6 YEARS OLD AND OVER 100K MILES I "SHOULD EXPECT " THESE KIND OF PROBLEMS. ON JULY 24, 2011 SHORTLY AFTER ENTERING THE HIGHWAY THE ENTIRE LIFTGATE WINDOW PULLED AWAY FROM THE VEHICLE. I AM ABOUT TO OPEN ANOTHER COMPLAINT WITH GMC, BUT EXPECT LITTLE HELP FROM THEM. APPARENTLY THE WINDOW AND SPOILER ARE BOTH ATTACHED WITH DOUBLE SIDED TAPE ON THIS MODEL YEAR.A DEFINITE DESIGN FLAW. IT IN MY OPINION IS A HAZARD TO ANYONE DRIVING BEHIND ONE OF THESE VEHICLES AND SHOULD BE RECALLED AND THE WINDOWS AND SPOILERS "BOLTED" INTO PLACE. *TR

2006 ENVOY DENALI CHECK ENGINE LIGHT CAME ON FUEL GAUGE STOPPED WORKING PROPERLY. DEALER SAYS IT IS THE SENDING UNIT. IF THIS IS COMMON SHOULDN'T THERE BE A RECALL. *TR

TL* THE CONTACT OWNS A 2006 GMC ENVOY DENALI XL. THE CONTACT STATED THAT THE CHECK ENGINE WARNING LIGHT ILLUMINATED. THE FUEL GAUGE ALSO FLUCTUATED BETWEEN EMPTY AND FULL ANDWOULD NOT PROVIDE AN ACCURATE READING. THE DEALER WAS INFORMED OF THE FIALURE AND THE CONTACT WAS AWAITING A SERVICE APPOINTMENT. THE MANUFACTURER WAS NOT AWARE OF THE FAILURE. THE CURRENT MILEAGE WAS APPROXIMATELY 56,000 AND THE APPROXIMATE FAILURE MILEAGE WAS 55,000.

MY FUEL LEVEL SENSOR IS FAILING TO TELL ME THE TRUE AMOUNT OF FUEL LEFT IN THE TANK. I OFTEN SAYS THAT THE TANK IS EMPTY BUT MANY TIMES IT CHANGES FROM 3/4 FULL TO 1/2 FULL AND SOMETIMES BACK UP TO FULL THEN EMPTY. I REPLACED THE FUEL LEVEL SENSOR AND IS NOW WORKING. I DO HAVE THE OLD SENSOR AVAILABLE. 2006 ENVOY DENALI XL. *TR

2006 GMC ENVOY DENALI XL- FUEL GAUGE IS BROKEN. GOES FROM EMPTY TO FULL OFTEN. I'VE SEEN SEVERAL OTHER COMPLAINTS ABOUT THIS AND THE DEALERSHIP IS SAYING THIS IS A COMMON PROBLEM...WHERE IS THE RECALL???? *TR

ABOUT 4 MONTHS AGO, AT AROUND 42,000 MILES, AFTER FILLING UP THE FUEL TANK, THE FUEL GAUGE STARTED FLUCTUATING FROM FULL TO EMPTY. FOR A FEW MONTHS THIS WOULD ONLY HAPPEN WHEN THE FUEL TANK WAS ABOVE FULL, BUT LATELY THE FUEL GAUGE WILL DROP TO EMPTY FOR LONGER PERIODS OF TIME AND AT ANY FUEL TANK LEVEL NOT JUST WHEN IT IS FULL. THIS MAKES IT REAL HARD TO KNOW HOW MUCH GAS IS LEFT IN THE TANK AND WOULD MAKE IT POSSIBLE TO RUN OUT OF GAS. *TR
