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.

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

GAS GAUGE AND FUEL SENSOR STOPPED WORKING, TWO ESTIMATES TO REPAIR OF $800.00. THIS IS AN EXTREME SAFETY ISSUE NOT KNOWING HOW MUCH FUEL IS IN YOUR TANK.
