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.

My vehicle was repurchased by GM recently. The dealership that handled the transaction was vandergiff Chevrolet in arlington, tx. They did not respond to my calls. They ignored my request. They did not follow through on the paperwork required by GM, and they lied to GM and myself regarding filing the "warranty' with GM resulting in additional time that I had to wait in order to have the vehicle paid off to my loan institute and the remaining funds to me so that I could acquire another vehicle.
