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.

2007 Chevrolet Trailblazer Owner Comments

problem #1

Jun 262009


  • 32,000 miles


The contact owns a 2007 Chevrolet Trailblazer. While driving 55 mph, the anti-theft system flashed three times on the instrument panel before the fuel line failed. The vehicle lost power and the contact managed to pull the vehicle over and turn it completely off. After 15 minutes, she attempted to restart the vehicle and then turned it back off. She restarted the vehicle a few times before driving back on the freeway. The dealer performed a diagnostic, but there were no failure codes showing up on the computer. The dealer discovered that the ignition switch shorted internally. They replaced the ignition switch, but were unable to confirm if the vehicle is permanently repaired. The current and failure mileages were 32,000. Updated 08/14/09. The consumer stated since the dealer replaced the ignition switch, the vehicle continues to shut off because there is a problem with the anti-theft system. Updated 08/17/09.
