MY FUEL GAUGE STOPPED WORKING IN MY 2005 ENVOY AT APPROXIMATELY 40,000 MILES. THE FUEL GAUGE INDICATES THAT THE CAR IS OUT OF FUEL AFTER FILL THE TANK FULL. I HAVE NOTICED NUMEROUS COMPLAINTS ABOUT THIS PROBLEM AND HAVE ALSO RECEIVED A LETTER FROM GM STATING THAT THEY ARE AWARE OF THE PROBLEM AND WILL COVER UP TO 50% OF REPAIR AS MY WARRANT HAS EXPIRED. THE PROBLEM WITH ONLY COVERING 50% IS PAYING WITH FOR MY HALF OF THE REPAIR. I HAVE BEEN UNABLE TO COME UP WITH APPROXIMATELY THE $200 FOR THE REPAIR THEREFORE UNABLE TO HAVE IT REPAIRED. I SPOKE WITH GM CUSTOMER SERVICE AND THEY INFORMED ME THAT WAS MY OPTION. WHEN I ASKED WHY THERE HAS NOT BEEN A RECALL ON THE PROBLEM THEY INFORMED ME THAT I SHOULD CONTACT THE NHTSA. MY CONCERN IS THAT I LIVE IN A STATE WITH COLD WEATHER THAT REQUIRES THAT CAR TO WARM UP PRIOR TO DRIVING. SO I WAS KEEPING TRACK OF MY MILEAGE KNOWING WHEN I NEEDED TO FILL UP WITH GAS. ALTHOUGH, THIS WILL NOT BE ACCURATE IN WINTER AND AFRAID THAT MY SPOUSE (PRIMARY DRIVER OF THIS VEHICLE) WILL GET STRANDED ON THE ROAD. I HOPE IF/WHEN THIS HAPPENS IT IS NOT DURING A SNOW STORM WHERE AN AUTO ACCIDENT WILL THEN BECOME LIKELY. WHEN TALKING TO GM ALONG WITH THE FUEL SENSOR I EXPRESSES CONCERNS ABOUT OTHER ISSUES THAT I HAVE BEEN HAVING. FOR EXAMPLE, MY LICENSE PLATE LIGHT STOPPED WORKING, CHANGED THE BULB AND CHECKED THE FUSES AND STILL DOES NOT WORK; ALONG WITH HEAT ISSUES AND WAS INFORMED TO TAKE IN FOR DIAGNOSIS. *TR

THE SPEEDOMETER FAILS TO REPRESENT TRUE VEHICLE SPEED. USING A GPS WE CAN MONITOR THE INACCURACY IN THE GAUGE READING. THE SPEEDOMETER REFLECTS A SPEED OF 25 WHEN ACTUAL SPEED IS 45. THIS BECOMES WORSE AS THE VEHICLE IS DRIVEN AS THE SPEEDOMETER COMPLETELY FAILS TO REGISTER SPEED. AN IDENTICAL ISSUE WAS PRESENT ON A 2003 CH…

THE SPEEDOMETER FAILS TO REPRESENT TRUE VEHICLE SPEED. USING A GPS WE CAN MONITOR THE INACCURACY IN THE GAUGE READING. THE SPEEDOMETER REFLECTS A SPEED OF 25 WHEN ACTUAL SPEED IS 45. THIS BECOMES WORSE AS THE VEHICLE IS DRIVEN AS THE SPEEDOMETER COMPLETELY FAILS TO REGISTER SPEED. AN IDENTICAL ISSUE WAS PRESENT ON A 2003 CHEVROLET TRUCK WE OWN WHICH WAS REPAIRED BY GM UNDER AN IN-HOUSE PROGRAM RESULTING FROM A LAWSUIT. GM HAS DECLINED TO REPAIR THIS SAME PROBLEM ON THIS MODEL. IF A DRIVER CANNOT ACCURATELY DETERMINE HIS/HER SPEED AT ANY GIVEN MOMENT THE POSSIBILITY FOR SAFETY RELATED INSTANCES ARE INCREASED FOR THE DRIVER AND OTHERS. *TR

FUEL SENSOR, LOCATED IN GAS TANK, HAS FAILED. NO MATTER HOW MUCH GAS IS IN THE TANK, BE IT FULL, HALF FULL, OR LESS, THE SENSOR BELL RINGS AND THE GAUGE REGISTERS EMPTY. THIS ALSO CAUSES THE CHECK ENGINE LIGHT TO COME ON. GMC SHOULD RECALL, AS THIS IS VERY DANGEROUS. I THOUGHT I HAD MORE FUEL BUT RAN OUT OF GAS ON A MAJOR RO…

THIS ALSO CAUSES THE CHECK ENGINE LIGHT TO COME ON. GMC SHOULD RECALL, AS THIS IS VERY DANGEROUS. I THOUGHT I HAD MORE FUEL BUT RAN OUT OF GAS ON A MAJOR ROAD, THANKFULLY NO ACCIDENT. GMC HAS ADMITTED THERE IS A PROBLEM AND HAS AGREED TO PAY 50% OF REPAIRS, BUT THIS IS ONLY DONE UNDER A VEHICLE WARRANTY EXTENSION, NOT RECALL. *TR
