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.

2006 Chevrolet Trailblazer Owner Comments

problem #1

Sep 292007

Trailblazer 6-cyl

  • Automatic transmission
  • 12,000 miles


The contact owns a 2006 Chevrolet Trailblazer. While driving 35 mph, the brake pedal was resistant when it was depressed. The vehicle would not stop and the contact rear ended another vehicle. The road conditions were dry and there were no warning indicator lights prior to the failure. The air bags failed to deploy. A police report was filed. The front bumper was damaged and the vehicle was towed to the contact's residence. The mechanic was unable to determine the cause of the brake failure. The manufacturer stated that the speed was not fast enough to make the air bags deploy. The driver was wearing her seat belt, but she reinjured her back and experiences numbness in her legs. While driving between 30-60 mph, the engine would stall and the check engine warning light flashed. The vehicle would not restart and was towed to the dealer. The dealer stated that the failure was caused by a failed seal that caused water and orange sludge to build up in the engine. The engine was cleaned and the failed seal was replaced. The frame around the license plate was leaking tar. The dealer informed her that the tar was coming from the tailgate. She applied tar remover to the tailgate and license frame and no longer experienced the failure. The failure mileage was 12,000 and current mileage was 14,000.
