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.

Headlamps have gone off and/or turned back on while driving or starting up. High beams work. This problem was supposed to have been repaired in the last recall. My local dealer replaced the module causing the trouble. Now the same problem is happening again. This is happening off and on haphazardly. Can't depend on having lights when I want to go out at night. I want this fixed.

Lines, body work-rust both rear side doors, spare tire winch, ect.when I road tested with dealer plate two days in a row found out my low bea M or daytime running lights would not work at times. Real problem at night. I understand there is a recall for this problem. My local dealer does not show recall for my VIN. #. this Trailblazer needs to be included. Driving in dark back roads at night very dangorous. Oncoming trafic dont like my hi beams. Spoke with past owner, he said this happened to him 3 OR4 times at night to him. My dealer wants me to pay for parts and labor. He is sure it is headlight driver module like recalled vehicles. Let me know if in need to scream at Chevy. Thank you for help.

The headlights will go out while driving the vehicle. There is currently a recall for this problem for Trailblazers. It is GM safety recall 14291. The problem is the headlamp driver module. I contacted GM. After giving them my VIN number, they told me that my vehicle is not included in the recall. The problems I was having matched exactly what this recall is fixing. I believe my vehicle should be included.

When driving with headlamps on low beam, intermittently both headlamps will go out. This happen to me while driving down a steep, curvy, highway on a rainy night. I was facing an oncoming big truck, in a sharp curve. Dimmed my lights and everything went totally black on my vehicle. All I hear is the horn of a big truck as the driver is trying to avoid my vehicle. I called my dealership and took my vehicle in only to be told that this make and model is not on recall, yet. So I am out of pocket for the repair, while other GM vehicles are on recall for this same problem. Called GM, was basically told, no recall, your problem. I have been a GM customer for 30 years, not anymore.

Trailblazer

Low beam headlight failure. While driving at night, the low beam headlights randomly fail. The vehicle is in motion. When they fail, I can't see in front, and on surface roads, oncoming traffic can't see me. The vehicle was recalled for this very reason, and my vehicle is in that group, but when the VIN number was checked my vehicle wasn't on that list. I don't have the recall number, but I found out online my vehicle should be included in that recall.
