Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“I was driving the truck and the fuel gauge was reading that there was gas in the tank. The vehicle died causing loss of power steering and power brakes. I was able to pull the truck to the side of the road with great effort. Had my wife or teenage daughter been driving the outcome might had been very different.after filling the gas tank the gauge went to e and never worked properly afterwards.”
NHTSA complaint #10587546, filed 2014-05, 90,000 miles“I have a 2006 chevy trailblazer. Since my vehicle hit 69000 miles my fuel gauge has become inoperable. I have tried to get it fixed but it is $1300 and no guarantee that it will not happen again since the part has not been changed. It stalls on many occasions as if I have no gas. I have run out of gas so I know how many miles I can go.”
NHTSA complaint #10399072, filed 2011-05, 69,000 miles“The fuel sensor in my 2006 Chevrolet trailblazer has been spuriously failing. It does not accurately represent the amount of fuel that is in my tank. Sometime it will say that my tank is full when I know that it is not, and sometimes it will say that my tank is empty immediately after filling it. My car has 65,000 miles on it.”
NHTSA complaint #10411842, filed 2011-07, 65,000 miles“Fuel gauge has failed. At any given time, I am uncertain of the amount of fuel in my gas tank. I have contacted the dealer, they said they would diagnose the problem for $99, and the repair could cost $600 - $800. This is an obvious defect and should be replaced by GM as part of a recall. Since I could run out of gas at any time, it is obviously a safety issue.”
NHTSA complaint #10341973, filed 2010-07, 50,000 miles“The fuel gauge sensor is malfunctioning in my 2006 chevy trailblazer. In reading on-line posts, this is a common problem that GM is ignoring. I already had to pay out of pocket for a rear differential that snapped about 7 months ago. Now I have to deal with a gas gauge that could potentially leave me out of gas or even cause problems with the fuel pump.”
