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.

On 9/24/08 I was involved in an auto accident where my 2007 Chevrolet Trailblazer's airbags failed to deploy. My vehicle impacted another with my entire front end at approximately 45 mph. My Trailblazer was totaled. Not only did my airbags fail to deploy, the onstar system did not automatically go off. I had to hit the button to summon assistance. When we asked the dealer about it, their response was "sometimes they go off, sometimes they don't" I sustained a broken left arm, numerous bruises, a cut on my ankle and an ankle sprain. I also injured my back and neck which is requiring ongoing care.
