NHTSA Complaint #10559725 — 2005 GMC ENVOY

AT LEES THAN 1/4 TANK OF FUEL THE GAS GAUGE IS CLOSE, AFTER REFUELING, THE FUEL GAUGE GOES WAY PAST FULL AND WILL STAY LIKE THAT UNTIL FUEL IS BELOW 1/4 TANK. LAST TIME THE TRUCK TOOK 19.85 GALLONS IN A 20 GALLON TANK UNTIL IT STARTED WORKING CORRECTLY AGAIN. ONE TANK IT WORKED FINE AND NEXT FILL UP IT WAS WAY BEYOND FULL AGAIN. AT THE SAME TIME WHEN FUEL GAUGE IS WRONG, THE SPEEDOMETER WILL BE OFF. MANY TIMES FREEZING AT 35MPH WHILE TRAVELING 65MPH. AFTER MANY RESETS OF IGNITION, THE SPEEDOMETER WILL COME BACK. ALSO WHEN ALL OF THIS IS HAPPENING WITH THE SPEEDOMETER AND FUEL GAUGE, THE RADIO HAS NO AUDIO. EVERY NOW AND AGAIN, THE RADIO WILL COME BACK AND WORK ON ONE SPEAKER. MOST OF THE TIME IT IS OUT. WHEN WEATHER IS WARMER, ALL 3 FUNCTIONS SEEM TO WORK REGULARLY. BELOW 50 DEGREES, ALL MALFUNCTION. *TR
