CarComplaints.com 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.

2007 Chevrolet Trailblazer Owner Comments

The mechanic said this is a recurring problem with the Trailblazer. Since mine is only two years old I think this is a bad reflection on GM's ability to build cars. No wonder they are going bankrupt! The warranty has expired mileage wise, but with this known ongoing problem, GM should pay for repairing it. I've bought GM vehicles for many years, but this is the last one

for me.
