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. 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.

ABS always engaging at low speeds, issue cause by ABS module located under vechicle, gets wet or moisture, poor GM design, poor location to pit electronics under vechicle. Alota of people online have same issue spening over $1000 on new module does not correct problem per online forums.

The manufacturer was not made aware of the failure. The failure mileage was 136,000.

All of the lines on my vehicle (fuel, brake, power steering) have really bad rust corrosion. These will have to be replaced before there is a serious failure. The truck is only a 2007 and the lines look like it's a 1987.

Trailblazer 6-cyl

While driving at 45 mph (foot not on the gas, going downhill) the vehicle lost all power. Was approaching a stoplight and brake to stop. After truck came to full stop due to me braking for light anyhow, brake pedal became hard, unable to push down or pump. Stopped at traffic light not knowing what happened since gas tank was full, I shut key (truck) off, and on waited till light turned green, it restarted on the first attempt thank goodness. Why the complete powerfailure while driving at 45 mph, I have heard this could be onstar related, even though I am not signed up as a customer, if a Trailblazer 07 is stolen or in an accident, I heard the onstar features confusion w/ satellite and causes them all to shut down. Don't know if this is true, but something went way wrong, luckily no one was hurt or I'd be suing bigtime. Today is 10-12-12, yesterday got a recall notice in the mail for door/windows/locks problem. They will fix for free however no parts to replace are currently available, really"?" wow.
