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.

Avoid the trailblazer at all costs this thing leaks oil, burns through water pumps, and wears down tires fast!

Trailblazer ES Inline 6

  • Automatic transmission
  • 126,000 miles

This SUV has cost me nearly $15,000 in electrical and engine repairs. It has nearly bankrupted me, and it has placed my wife and youngest daughter in serious danger several times. I've reported problems to the NHTSA and GM on two occasions. GM has offered nothing.

I would like to know whether there are any class-action lawsuits underway or pending on the Trailblazer. Mine is the 2008 model.
