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

problem #1

May 312008


  • 70,000 miles


I was stopped for my tail light being out. The next day, I replaced all of the fuses in the rear of my Trailblazer. Everything seemed to work, but then two weeks later I was stopped again for my tail lights not working. I replaced all the fuses, even though it was on one side (passenger side) then checked the circuit board, still the top tail light will not work. Found out that it does not work, when head lights are on..that is why I was getting pulled over at night. Only one tail light is not working and I can not drive at night because I keep getting pulled over because of this defect. It comes out of the blue. I have noticed that my right blinker sometimes blinks really fast. Also, over the past month I have experienced a total power failure in my Trailblazer. Nothing will work...its like the car was unplugged...totally out and will not turn over, no lights, radio and power to ignition...sometimes I can not remove my key or change into neutral....completely drained of all power...where I need a jump, then it works fine, but the tail light is still out when my head lights are on. I am afraid of having a total power failure when driving, especially since my tail lights will not work the head lights are on.
