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.

The contact submitted an email and requested that the official IVOQ be written verbatim to the email: I have a 2007 trailer Blazer and had these problems for 2 years. Gas gauge would show 1/4 to 1/2 tank but ran out of fuel twice. Gauge shows empty all the time now. Service department said it's a bad sensor in tank and will cost $ $800 to fix. This has been a problem with GM for 3 or 4 years. 1,000's of complaints on different forums. The failure mileage was 30,000. Updated 09/27/11 updated 10/11/11
