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.

The contact owns a 2007 Chevrolet Trailblazer. While driving approximately 25 mph on normal road conditions, there was a low power response when the accelerator pedal was depressed.

The vehicle was taken to the authorized dealer for inspection and they stated that the failure was related to the throttle body freezing. The throttle body was replaced.
