What owners report
I filled up my 2005 GMC Envoy XL slt when it had 71,000 miles. I had no previous fuel gauge issues. Started the vehicle and fuel gauge went to empty even though I had filled it completely. I don't have the money to repair so have been driving it for the past month and this has been a daily issue while driving. The fuel gauge fluctuates between empty and full and will stick on empty and the bell chimes constantly even when I just filled it up. I have no way of knowing exactly how much fuel is in there except to monitor miles driven and fill it back up more frequently. I feel this is a safety issue. What if my calculations are incorrect and my vehicle stalls on the highway. I have two young children and am afraid of a stall happening resulting in a crash. The fuel gauge is not working. I have no way of knowing exactly how much gas is in there. …
Faulty fuel gauge on 2005 GMC Envoy, slt. Everytime the tank is filled, the gauge in the instrument cluster reads empty - sometimes it will rise to about an eighth of a tank, but shortly thereafter, it will go right back to empty. This problem has persisted for over a year now. There are thousands of participants on online forums with the same problem for several various GM brands. The average cost to rectify the problem is well over $500.00. The problem not only affects recent model vehicles but, it appears to affect earlier GM model vehicles as well, some as old as 1998. The problem appears to be a known defect, as many people have taken their vehicles to mechanics and/or the dealership to have the problem addressed. Nothing has been done to rectify the problem nor provide a resolution to the problem. …
