NHTSA complaint #10960069, filed 2017-03, 110,000 miles“My fuel gauge keeps fluctuating. Even when I have a full tank of gas, the gauge fluctuates, and goes to empty and the low fuel light comes on. This happens when I am parked, stopped at a light, and going down the road. It doesn't matter what speed I'm going, the gauge goes to empty and the light comes on. It happens when I have a full tank, half tank, quarter tank. Please help!”
NHTSA complaint #10511734, filed 2013-05, 83,800 miles“I own a 2006 Gmc Envoy. The gas gauge is reading empty even when it is full. I have researched this and found many people are having the same issue. I feel that this is a safety hazard because if I run out of gas while driving it could result in a rear end collision. Not to mention that this car is new and shouldn't have these type of issues.”
NHTSA complaint #10386344, filed 2011-03, 60,000 miles“I read in the newspaper that the NHTSA had opened an investigation concerning 2006 Gmc Envoy gas gauge problems. I have the same problem as many others with the gauge fluctuating. This should be considered a safety issue since it could cause someone to be stranded. I have 53000 miles on my Envoy and this problem started about a month ago.”
NHTSA complaint #10399371, filed 2011-05, 51,500 miles“The gas gauge on my 2006 Envoy starting acting crazy going from empty to full and mostly staying on empty all the time. This has been a command problem with this model and other GM vehicles and should be recalled. I haven't been left on the side of the road or rearended yet from running out of gas, but it's certainly a concern.”
