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.

Trailblazer 4WD

  • 36,000 miles
2006 Chevrolet Trailblazer, 4dr, lt, 4WD. Fuel gauge stopped working. Fill up tank, gauge goes up to full, but then falls back down to empty. I do not know the level of fuel in my vehicle. Appears to be a common problem among 2003-2006 Trailblazers. Have ran out of fuel on the road. Most likely fuel sensor or cluster.
