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.

  • 235,000 miles


The airbag deactivated light on the dash cluster comes on and off but mostly stays on now. No codes showing the cause. While driving both low beam headlights suddenly turned off, later diagnosis showed an electrical issue that melted both low beam light connectors and wires at the bulb end, new connectors were installed. Two different times within 1yr the heater blower motor relay has gotten hot enough to melt the connector and burn out the relay, connector replaced twice and currently melting again as fan speed 1, 4, and 5 have again stopped working. Heater blower motor also replaced twice concurrent with relay.

2006 Chevy Trailblazer spun out on snow while my daughter was driving. It went towards the left then immediately jerked around to the right and continued to gain speed as it launched us off the roadway and into a group of trees. The brake pedal wouldn't budge, the steering wheel continued to turn in circles not controlling the tires at all. The backseat broke apart before impact and was throwing my teenage son around in the back. The front seats broke loose as well and slammed both driver and passenger into the dash during impact. The seatbelts did not engage to lock into place like they are supposed to and despite full frontal damage and a SUV deemed totalled/destroyed by my insurance company, not a single airbag deployed or attempted to deploy. We were all trapped inside the vehicle down an embankment and all sustained injuries in the crash including cuts, bruises, whiplash, and my daughter had a concussion. My daughter had a vp shunt placed in her brain last year and could've easily died in this crash due to her injuries. Something needs to be done about these airbags and seatbelts not working!!

My son was in an accident in his 2006 Trailblazer. He was crossing a city street intersection when another vehicle struck his truck on the drivers side at an estimated 40+mph, the truck flipped and slid about 15-20 feet. None of the airbags deployed.

I was in a crash and neither front airbag deployed, my insurance adjuster questioned if the air bag system even works. I have copy of the estimate to repair as well. Due to the force of impact even local repair shop stated that my air bags should have gone off as well. Is there a recall on this model for air bags not deploying? I was in a second wreck on 3/7/17 and neither air bag deployed at that time either and there was no bumper so air bags should have definitely gone off.

Letter from senator nelson on behalf of constituent regarding general motor safety defects. The consumer suggested there was a defect with the GM air bags in 2006 Chevrolet Trailblazer, in which the driver sustained a brain injury and his wife was injured, when it was impacted on the driver's side, resulting in left A-pillar contact when the air bag failed to deploy and his seat belt restraints failed. The crash was of enormous severity, with a speed change of 38 mph with a line force in the direction of the a pillar.

I was involved in an automobile accident out of state. I was traveling during the evening hours to try to avoid heavy traffic. I started having trouble with the dim lights and could only proceed using the bright lights. The next thing I realize is that I am unable to control the vehicle and struck another vehicle on the road. I then proceeded to slide down an embankment approximately 30 feet. My vehicle sustained enormous damage to the front and side of the vehicle. The front airbags did not deploy and my vehicle was deemed totaled by my insurer.

I was driving down the highway and had got cut off by a car. I swerved and avoided hitting the car but ended up hitting the median almost directly head on. The whole front of the vehicle was smashed in and the vehicle was totaled. The airbags never went off, me and my passenger were both wearing our seat belt and I ended up hitting my head on the steering wheel leaving me unconscious. An ambulance rushed me to the hospital and I received 10 stitches above my left eye.

This complaint is being filed on behalf of the vehicle owner and driver. This Chevy Trailblazer was involved in a two vehicle, double fatal crash. The front of the Trailblazer struck the driver's side door of a cavalier that failed to yield from a stop sign. The Trailblazer stayed connected with the cavalier, forcing it off the left side of the roadway and into a large tree. Both occupants in the cavalier were fatally injured. The front airbags did not deploy on the Trailblazer and no event was recorded on the airbag control module.

I purchased a used car from ez cars & credit located in riverside California because they had some very good reviews. I could of bought a car from a private owner but I decided to go with a dealership because I figured that the law would protect me and they could not sale me a defective vehicle. I purchased an SUV, Chevrolet Trailblazer 2006 on 2/07/2013 and after taking the car for a test drive, I noticed the airbag light on. The manager [xxx] said it was just something that could be fixed in like 5 minutes and that it had to do with the fuses being replaced but his service technician left for the day so I should bring the car in tomorrow. I contacted the dealership and asked for [xxx], I was told by the sales manager who's name is [xxx], that [xxx] was on vacation for 1 week in Mexico. I explained the airbag situation and[xxx]said he doesn't know anything about it and I would have to wait for [xxx] to return from Mexico. A week and a half later driving with the airbag light on, not knowing if my kids, husband or myself were safe in this vehicle but we spent all our money to purchase this car. We here from [xxx] so I brought the car into the dealership, [xxx] had the car for 4 days and the airbag light is still on today! I contacted [xxx] and told him I was on my way to pickup my car, mr. [xxx] he was at the office, now when I pick up my car, I get my keys from the owner of the auto repair shop next door. He doesn't even work for the dealership! I have serious water corrosion under my car, the steering wheel feels shaky the fuel gauge never reads correctly and the lights go off and on inside the car after a while of driving. I don't know what to do?? information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).

I was driving on highway 20 heading towards North Carolina. I was about 5 to 10 miles from meridian, ms and I was driving into a down pour of rain. Two semis passed me splashing water and after the second semi passed all I knew was my vehicle spinning out of control at a rapid speed bouncing up and down for about 30 to 50 yards and finally slamming into a tree on the driver side and the airbags did not deploy. I myself sustained minor injuries along with my oldest son. My two younger sons were in the backseat but I had a basket next to the drivers side passengers door which made one of my son's sit in the middle and my other son to the right of him.

In approximately April of 2010 my gas gage on my 06 Trailblazer quit working. The part was no longer under warranty at 84K miles. Very dangerous when traveling 400 miles with elderly aunt and small child 2X a week. On October 1, 2010 I was involved in a high speed collision when a car pulled in front of me, while I was going 70mph. The airbags did not deploy, I suffered major trauma to my knees and am unable to walk well or drive. I hit my head on the steering wheel and continue to have pain. My elderly aunt broke 3 cervical vertebrae and still has a trachiotomy over a month later. She is still in the hospital, and it is unknown if she will come home.
