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.

  • miles
2005 Chevrolet Trailblazer. The fuel gauge stopped working without warning. The consumer stated it didn't matter how much fuel was in the gas tank, the gauge read empty and the amber warning light and alarm intermittently engaged, even when the fuel tank was full. There was no way to accurately confirm how much fuel was in the vehicle at any given time. While enroute to the dealer, the consumer ran out of gas. The consumer finally made it to the dealer and upon inspection, the consumer was informed the fuel sensor was defective and needed to be replaced which required the gas tank to be removed from the vehicle.
