Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

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 have had nothing but problems with my 06 Trailblazer. The front windows rattle horribly, there is a film that is all over the windows all the time, the passenger door speaker has been replaced going on 4 times now, the power points have been replaced, also the stabilizer (which I do not think are fixed) and now they are replacing the stereo in it. They tell me the problem with the windows is "it's how they are made and they all rattle", power points..."don't use them"...speakers..."turn the music down"...stabilizers I have given up on. And now there is a smell like something is burning in the car. It does not happen all the time, so there is no way to point it out. This is the first for the stereo. I can not drive with the windows down..they even rattle when up!

Trailblazer 4WD 8-cyl

  • Automatic transmission
  • 18,850 miles
We have had two 2006 Trailblazers and both of them have been nothing but problems for us. The first one we brought we owned it for six months and we had it in the shop six times (broken sway bar, heater two times, windshield wiper fluid holder two times, shaky front wheel and motor misfiring. We traded in hopefully to avoid more problems and went ahead after assurance that this one must just be bad and got another 2006 Trailblazer. This one we have only had for 2 months and we're already having problems. Three days after we bought it had to go to the shop for the radio not working properly. Then the engine starting misfiring and the engine light was on and it was running really rough. The tech thought that it was happening because the gas cap wasn't all the way tightened. (when the engine light comes on you loose power and I pulled out in front of a car on the highway and barley moved that's how I found that out.) when he called me back he said that I had two cracked sparks plugs and the battery cable was loose making it start slowly. That was fixed but then 5-27-07 the engine light came on again and it was running rough just like before. It seems like everytime that the engine gets wet that it makes it misfire. I told the dealership this several times now. It had been raining that day. Everytime I take it in for the engine they tell me there is a lot of moisture under the hood on the motor. It's in the shop right now.

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.
