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.

I purchased a brand new Chevrolet Trailblazer at the end of 2007. Since then, I have had multiple service issues with the car, most notably a faulty front axle that had to be replaced. In January 2009, my service 4WD light came on and I could not put my car into 4WD. I immediately took my car to the dealership, who could not find a problem and returned my car to me. A week later, I was driving my car in the snow in 4WD, getting ready to enter the highway, when the car stalled and the service 4WD light came on again. I returned to the dealership, who kept my car for 3 days and again could not find the problem. They returned my car to me and said "you probably got snow in your muffler". I drove my car in 4WD periodically for the next 19 months trusting that my car was safe. When the same problem happened again at the end of Nov 2010, I took my car to a different dealership who told me I had a bad front axle and 5 bad gears that were binding, and that I could not drive my car in 4WD until this was repaired. I have also had to have an O2 sensor replaced, several body system repairs, and yesterday my service stabilitrack light came on and stayed on until I restarted the car. I have asked Chevy to buy back my car, as it is clear I have a poorly manufactured and unsafe vehicle, and they have only offered to cover my body systems parts under warranty. I feel unsafe in my car and I don' T know where to turn for help.
