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.

  • 28,700 miles


Two weeks ago we put new tires on my Trailblazer at 28,700 mi. We were leaving for a trip and took it to have the front end aligned to be sure the new tires wore properly. We did not go to our dealer as there was no time before the trip. Upon checking the car, they discovered both my front struts were leaking badly and they no longer gave a firm ride. We had no choice but to have them replace both struts at only 28,700 mi. The repair shop was quite surprised that both struts were bad. My Trailblazer is garaged, has extremely low mileage, is driven only on city streets or freeway and never carries any loads. Even though we were past the 36 mo. Portion of the warranty, the repair shop told us that they felt the struts should have lasted far longer than 28,700 mi. And that with the excellent care of my car, it was far too early for them to have to be replaced. I checked with some friends who had their cars for far longer than me and many more miles on it and they had never had any issue with struts. I decided to contact GM to file a complaint. They contacted me and the interviewer told me that she completely understood why I would be upset. However, today I was called and told that they would not help with any of the cost for replacement of the struts. My concern is for the safety of other people that own Chevy vehicles with the same struts. We were told that we should not drive our car with the bad struts on the freeway because it was not safe. I want to file a formal complaint so that others can be made aware of the possible dangers of the struts failing at such an early mileage. I plan to contact whatever agencies necessary to make sure the public knows about the problem.

Trailblazer 4WD 6-cyl

  • Automatic transmission
  • 8,000 miles
I have had many many problems with my 2006 Chevrolet Trailblazer most recently the transmission is bad, I had started complaining to the dealer about the transmission slipping at around 8,000 miles, the truck now has 17,000 miles on it. The dealer refuses to repair it under my warranty. The dealer will not cover the repair. The dealer told me I had to pay out of pocket. I was informed of this on 5/4/2007. I have had many many repairs done on this vehicle, something is not right. The dealer also refuses to fix the brakes, the dealer claimed to have repaired them 3,000 miles ago and told me that it is not possible for the brakes to be bad again, the dealer said I need rotors, pads, and they did replace a lt ft caliper that they found to be bad. The dealer will not replace the pads and rotors. The dealer has told me to pick my vehicle up. The vehicle is currently not in safe condition to operate on public highway, I informed the dealer that I will leave the truck there while I contact NHTSA and whoever else I find that will help me. If the dealer insist that I remove my vehicle, I will have it towed, I will not operate the vehicle on public highways, as it is not safe. I will now list some of the items most recently replaced. Also, ABS, check engine, and service 4WD lite was on and off since January 2007. The gas gauge malfunctioned. The instrument panel was replaced twice, also replaced the radio, front heater, rear heater, dvd player, both upper ball joints, brakes, ft wheel bearing, lt ft door control, ft calipers, some kind of bearing in the steering wheel. The front suspension still makes noise, rattles (the dealer cannot find the problem) there is more but this is what I remember right now without looking it up. The dealer also told me that it is not possible for so many things to be wrong and has accused me of changing parts over from another Trailblazer.
