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.

I will soon be replacing my 3rd fuel pump. You can not purchase a sending unit separately and you can not replace a fuel filter for maintenance. Also the master window switch stopped operating yesterday after a burning smell filled the truck. The master window switch is melted. Had issues with I first bought the truck with it "shutting down" on the highway, no gas, no power steering, no control. Received a year of free oil changes from Chevy after a complaint was filed, they still to this day can not tell my why my truck would randomly shut down.....updated 06/18/12 updated IVOQ 06/20/12
