2006 GMC Envoy fuel system, other problems

“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”

“THE FUEL GAUGE DOES NOT READ CORRECTLY. THIS HAS CAUSED THE VEHICLE TO RUN OUT OF GAS SEVERAL TIMES NOW IN THE MIDDLE OF TRAFFIC DUE TO THE GAUGE TELLING ME I HAD MORE FUEL THAN I ACTUALLY HAD. *KB”

“TL* THE CONTACT OWNS A 2006 GMC ENVOY. WHILE DRIVING APPROXIMATELY 65 MPH, THE CONTACT NOTICED THAT THE FUEL GAUGE DISPLAYED AN INACCURATE FUEL LEVEL READING. THE VEHICLE THEN SUDDENLY STALLED DUE TO THE LACK OF FUEL PRESENT IN THE FUEL TANK. THE ROADSIDE ASSISTANCE DISPENSED THE REQUIRED FUEL INTO THE FUEL TANK AND THE VEHICLE RESUMED AS NORMAL. THE VEHICLE WAS TAKEN TO AN AUTHORIZED DEALER, WHO STATED THAT THE FUEL TANK SENSOR WAS FAULTY. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE. THERE WAS AN OPEN INVESTIGATION UNDER NHTSA ACTION NUMBER DP10001 WHICH CLOSED AND A PRELIMINARY EVALUATION HAD BEEN OPENED. THE APPROXIMATE FAILURE WAS 81,000.”

“WITH NO APPARENT CAUSE, THE GAS GAUGE ON MY 2006 GMC ENVOY BEGAN FLUCTUATING WILDLY. IT FIRST HAPPENED AFTER I FILLED UP WITH A FULL TANK OF GAS- THE GAUGE IMMEDIATELY WENT TO EMPTY AND THE WARNING LIGHT CAME ON. EVER SINCE, THE GAUGE DOES NOT GIVE ACCURATE FUEL READINGS- IT WILL READ FULL WHEN EMPTY, EMPTY WHEN FULL, AND THE NEEDLE WILL SPIKE ALL OVER THE PLACE.. I CONSIDER IT TO BE A SIGNIFICANT SAFETY CONCERN- RUNNING OUT OF GAS IN THE MIDDLE OF HEAVY TRAFFIC CAN CAUSE SERIOUS ACCIDENTS. WAS DIAGNOSED AS A FAULTY FUEL SENSOR IN THE GAS TANK AND WOULD COST $700 TO REPLACE. *TR”

“I'VE GOT A 2006 GMC ENVOY AND THE GAS GAUGES NEVER READS FULL. IT'S ALWAYS READYING EITHER EMPTY OR FULL. I'VE BEEN DEALING WITH THIS FOR ABOUT 4 MONTHS NOW. HOPING THAT SOMETHING WOULD COME OF THIS BEFORE I JUST GO OUT AND HAVE SOMEONE FIX IT. MY CHECK ENGINE LIGHT IS ON DUE TO THIS PROBLEM. THANKS! *TT”
