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.

2005 Chevrolet Trailblazer Owner Comments

Trailblazer 6-cyl

  • 140,000 miles


The heater levels started to go out. First 5, then 1 until it no longer worked at all. I got it repaired but the 5th level does not work any more. The left half of the radio/cd player no longer lights up. My gas gauge would only register a quarter tank and then would eventually dropped to empty. It no longer works at all. Most recently my speedometer will occasionally quit working or register the wrong speed. I have to shut the car off and restart until it works again. Also, my tachometer goes way up when I begin driving and the car seems to rev way up before it changes gears and jerks into gear. I questioned a mechanic about this, thinking it was the transmission, which it isn't. there doesn't seem to be enough power. I have constantly had issues with this Trailblazer every since I purchased it. I also owned a Blazer at one time and also had a lot of trouble with it. I should have known better to purchase another Chevy, but never again!
