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.

Trailblazer 6-cyl

  • 104,000 miles


I have a 2006 Trailblazer and a few weeks ago my driver side control panel stopped working. Could not use my remote to open the door and was unable to put any windows down. I thought there was a short in the wires somewhere because the next day the panel worked. Now, two weeks later I stopped at the store and was getting out of the car and again I could not lock my doors using the button on the control panel. I left the door unlocked and when I came out (within minutes) my door window had gone down on its own while I was in the store. When I got into the car, my daughter and I could smell something burning. She immediately made me go to the garage and have her mechanic check it out. He was able to remove the panel and showed us where the plastic part that goes inside the handle had melted and could have caused a fire in the car. He called around to try and find a replacement part and was finally able to find one and was quoted over $300 for just the part!! then, I had to set up an appointment with the dealer to have it installed because it has to be programmed to my car and I was quoted about $103 for installation!!!! I can not believe this problem has not been listed as a recall after reading all the complaints with the same problem. I plan on getting a phone number from the dealer for the GM corporate office to file an automotive complaint tomorrow. I hope to be reimbursed for this part and the labor charge. This sounds like a serious safety issue to me and thank goodness my car did not start on fire while I was driving. Read more:

Trailblazer 4WD 6-cyl

  • 71,000 miles
The contact owns a 2006 Chevrolet Trailblazer. The contact stated that the driver side window started opening and closing independently. In addition, the side mirror started moving forward and backward independently and without activation. After parking the vehicle, the engine would shut itself off and the entire electrical system would become inoperable. Also, none of the doors could be unlocked and the failure would recur for several minutes before the contact would be able to restart the vehicle. The vehicle was then taken to the dealer who advised that the power window module was defective, causing all of the electrical system to become inoperable. The contact referenced NHTSA campaign id number: 12V406000: (electrical system) but her VIN was not included in the recall campaign. The manufacturer was notified of the failure who confirmed that the contact's VIN was not included in the recall, offering no further assistance. The failure mileage was 71,000.

Trailblazer 6-cyl

  • miles
The vehicle windows open and close randomly. The front driver panel controls all windows and will close the windows randomly if open. My child has been close to injured due to this. The side view mirror will randomly move in the downward direction while I am driving. The front driver door will stay locked even after turning the vehicle in park and shutting the vehicle off, locking me in. The manual switch to unlock the driver door doesn't always work either, so I need to climb over to the passenger side of the vehicle to get out. All these occurrences are dangerous to me and my children and I would like this to be addressed. I have contacted the dealership and GM and they said I do not fall under the recall due to my location, even though I spend a significant amount of time in the northeast coastal area. The dealer also refused to fix the problem saying they don't have the protocol on the recall repair of this vehicle. GM has that record. Updated 08/11/12

While on vacation in NY I went to move my Trailblazer to be able to pack up for the trip home and when moving it I noticed a strong smell of electrical fire and noticed smoke coming from the area around the drivers door master window switch. I quickly turned the truck off and pulled the switch plate out of the door but it was to late. The damage had already been done. The switch had shorted and melted all of the ribbon cable in the switch and rendered it inoperable. There was a slight misty rain when all of this occurred, I am just glad it happened in the driveway and not on the highway. I called and talked with Chevy and they told me there was no recall for this and there was nothing they could do to help and then stated that it was VIN specific. So which is it no recall or VIN specific?

Initially the interior lights as well as the head lights will flicker while the car is running in park. The drivers side window stopped working in April 2012. The other three windows continued to work. June 2012 the radio began to cut out when hitting a bump in the road. The dash radio lights would go blank and the clock reset to 12:00. This occurred on at least 4-5 occasions. Other times when hitting a bump the radio would make a static cut out sound but wouldn't fully go out. July 2012 on 3-4 different occasions all of the dash lights came on at once while driving down the road, the gas gauge dropped to empty on a full tank and the ding ding ding sound came on while driving. August 19, 2012, after driving about 8 miles the car smelled really funny like burning rubber or wire. Sniffing around the smell was originating from the front drivers side dash/door hinge area. At this time the rear drivers side window stopped working. The two remaining passenger windows continue to work, however hours later the smell still remains in the car.

This not a formal complaint, simply information. We had a 2006 Trailblazer that had the power equipment switchplate melt down when the vehicle was garaged. When I parked it the windows were up and when I went to the garage 2 hours later the drivers window was down and the smell of smoke came from inside the drivers door panel. Switchplate was in-operative. My point is GM know about this as early as 2007 and neglected to do anything about it. This Agency almost killed off Toyota for allegedly hiding known defects; perhaps it is GM, S time in the chair?

My 2006 Chevy Trailblazer driver side door caught on fire sometime early morning while we slept. Now my vehicle will not start and driver side door and window module is totally melted. I have had issues with other things prior to this. My door chimes stopped working. My air will not blow out of the vents and my radio speakers are not working. My teenager drives this vehicle so this is a big concern for me. I really would love GM to step up to the plate and honor their product. I feel taken advantage of. I have seen websites with complaint after complaint with the Trailblazer's electrical problems. We need a voice. Someone who has the power or pull to force Chevy to recall the electrical issues regarding their workmanship or the quality of their product. Updated 8/17/12

Our Trailblazer has the service engine light on and off constantly. Had it checked by our regular mechanic with the tester and it read the thermostat needed replacing which was done. The light is still going on and off and having it rechecked the reading said a problem with the cooling fan. Checked fan and nothing. The headlights go on and off. The windshield wipers come on by themselves and then off. When it is raining they only work on fast speed. The window cleaner comes on when the wipers due which is hazardous when it is raining causing a visibility problem. I will be going to the dealer with the check engine light as we are going on a long trip in two weeks. Didn't know there were so many problems with this vehicle as listed on the complaints section.

2006 Trailblazer was parked not running. When I opened the door there was a burning plastic smell and smoke coming from the drivers door. When I pulled the door window switch panel out, the side of it was melted and had melted part of the door panel, window, door lock, and window lock button don't work. I have to manually lock the drivers door, because the remote doesn't work on that door. Looked up recalls and was surprised when it wasn't on your website. Multiple complaints all over the internet about this same issue. Updated 08/21/12
