Three problems related to tank mounting have been reported for the 2007 GMC Envoy. The most recently reported issues are listed below.
Faulty gas gauge on my 2007 GMC Envoy. Does not show right amount of gas in tank. I have ran out of gas 3 times in the past 2 months. I've tried to keep track of gas by mileage, but that gets tricky.
Fuel tank light comes on and off constantly, gauge bounces back and forth. Occurs daily, several times per day. Changed gas cap, did not matter. Hazard and very difficult to judge amount of fuel. Should be a recall! 2007 GMC Envoy with 28000 miles.
2007 GMC Envoy fuel gauge not registering correct amount. Swings erratically from full to empty regardless of amount of fuel in tank. This is apparently a common issue with these vehicles based on internet message boards with fuel sensor failure most commonly cited problem. There is a risk of running out of fuel without warning and creating a hazardous driving situation. Have seen on msn that NHTSA is investigating so am adding my complaint to the pile and asking that gm be required to recall these vehicles to correct this defect. I have not paid for sensor replacement at this time.
