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.

CarComplaints.com 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.

While driving the, window switch began to smoke so I physically removed the switch and have since not had power window access on the passenger side front door. The cost to replace was too great and at the bottom of the priority list. More recently, maybe 2 months ago, the driver side switch showed signs of the same results after a smell of burning electronics and heat to the touch so I simply unplugged the switch all together. The cost to replace these switches is quite significant and have not had any luck with Chevrolet in the past with complaints so I figured I would wait until I had a little extra money to replace these switches. On the news today I heard the end of a report and only caught the words GM and window switches so I came home and searched and came across so articles involving 2006 models. That is how I came across this website. I would very much hate to find out that the company does not know the problem exists further than 2006. An unrelated problem I encountered with the vehicle, which was quite unnerving, was that the third brake light assembly came off while driving on a local highway at @ 65 mph approximately 2 years ago. The fixture became un attached from the passenger side and was "flapping" off the driver's side. Only for a matter of time, I'm sure. Luckily our family was being followed by another family and they notified us by cell phone and we were able to remove the fixture without incident on the shoulder. It would have caused serious problems without doubt had it come completely off. When we notified the dealership, they told us we were out of our warranty and were on our own. Thank you for taking the time to try to make our highways safer!

The fuel gauge does not work. This seems to be a very common problem, and GM's only remedy is to screw over consumers by making them pay for a known defective part out of pocket. This should be recalled and fixed at GM's expense, or they should at least offer a discount. Their $800 estimate is silly.

Trailblazer 4WD 6-cyl

  • 76,000 miles
At the time of purchase the owners noticed the rear brake lights did not work. The owners immediately return the car to the place of purchase for replacement of the brake lights. Several weeks later there was an issue with the vehicle speakers and that seemed to indicate an issue with the electrical in the car. While listening to the radio at any volume (low, medium or high) a high pitch, frequency or reverberation would happen. This is only when the radio is played, not when listening to cd's. the temporary solution is to firmly hit the middle arm rest to stop the reverberation. It's an annoyance but could potentially lead to other electrical issues and enormous costs. Please advice of either safety recalls, defects and possible service repair to the vehicle.

While driving to work my cruise control shut down and my speedometer stopped working. A couple weeks later the speedometer began working and now it has stopped again and stuck on 55 and doesn't move regardless if the vehicle is on or off. The cruise control won't work. I am very frightened to continue driving without knowing what speed I am driving. I can't afford to keep spending money on this vehicle to repair all the problems it's had. Wondering if the speedometer is covered under my 100,000 mile warranty. Please help.

Both the speedometer and gas gauge quit working. In doing research, this appears to be a problem with alot of other owners of this vehicle; this should be a recall. This could be a very dangerous combination with the speedometer not working and if fuel runs out on a busy highway for example. I was just quoted over $880 to fix and declined due to the cost.

Cluster instrument panel failed. RPM odometer doesn't work, speed ranges from 80-off the charts, gas gauge not accurate. Apparently big problem w/over 300 complaints yet no recall. Firestone just quoted me $700 for a remove and replace instrument cluster gauge. $600 for the gauge itself. I can't afford that.

Like many people my 2005 Chevy Trailblazer has several issues regarding the instrumental panel. The first time this occurred was during a cold snap and all of the gauges got stuck on the down or off position. After some time some of the gauges (ie. Speedometer, tachometer, and oil pressure ) starting working again however, the majority of the time the readings were inaccurate. After some time elapsed (this year - 2012) the tachometer and oil pressure gauge stopped working completely. This has become an extremely hazardous situation because no vital information is being provide to the driver and the manufacture will not fix the issue.

The lighting, both interior and exterior, flickers this causes disorientation and inhibits my ability to drive safely. It has also caused me to be pulled over by police because he thought there was something wrong in the vehicle. I do not even like driving at night anymore because I'm afraid they will go out completely.

My speedometer does not work at all. The heater and A/C don't work. My fuel gauge does not work. The interior lights inside my car do not work, the right front passenger window does not work. Basically my entire dashboard does not work. What did Chevy do about it?? sent me a letter stating they are willing to pay half of the cost to repair the fuel gage but it would have to be fixed at a Chevy dealership. I could get the same thing fixed at my mechanic and pay the full amount and it would still cost me less than having the dealership fix it and Chevy paying half the costs. Don't think I will be buying another Chevy anytime soon.

My gas gauge always reads empty even when the car is full. Engine light always goes on and off between a matter of days. Recently my heat went out in my car we changed the resistor and found out one of the prongs were burnt out. A week later the heat went out again. Looked at the resistor and the same prong was burnt out!! I'm getting really fed up with this vehicle!
