Print this page Notes: The 2002-2007 Chevrolet Trailblazer is known for many things, but perhaps it is most famous for its faulty fuel gauge.

This gauge flip-flops more than a politician during election season. Some report that the gauge says "empty" after a fill-up, while others report the gauge says "full" when they're running on fumes. Either way, there's one thing everyone seems to agree on: the darn thing is just wrong.

Following hundreds of complaints and a few accidents allegedly caused by the malfunction, the National Highway Traffic Safety Administration (NHTSA) opened an investigation into the issue in May 2011. Unfortunately for frustrated owners, no recall has been announced.

Fuel gauge reads empty when car is filled and the needle only moves a little..I never can tell how much gas there is.

  • miles
2005 Chevrolet Trailblazer. The fuel gauge stopped working without warning. The consumer stated it didn't matter how much fuel was in the gas tank, the gauge read empty and the amber warning light and alarm intermittently engaged, even when the fuel tank was full. There was no way to accurately confirm how much fuel was in the vehicle at any given time. While enroute to the dealer, the consumer ran out of gas. The consumer finally made it to the dealer and upon inspection, the consumer was informed the fuel sensor was defective and needed to be replaced which required the gas tank to be removed from the vehicle.
