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.

Just after purchasing the vehicle on December 29, 2008, I noticed the engine has accelerated and the car surges forward when stopped. If I do not keep my foot on the brake, there is a high potential of surging into the back of a vehicle in front of me. An accident has almost happened many times. I have had it looked at by the dealer I purchased the vehicle from on February 4,2009 and was told there is not a problem. It most likely will "not be a problem" until I rear end someone while stopped. This continues to happen on a regular basis, a year and a half later. I was not aware I had an opportunity to report until the Toyota recall happened. I have been living with it, anticipating the surge every time I am at a stop.

When I bought this vehicle 2 months ago, I thought the gas gauge was empty upon purchase, as it was a used car, but no it is the fuel system problem that everybody keeps mentioning. I fill the vehicle, and it only shows a half tank. Then it will go to empty with the warning light coming on. As someone who travels a lot, and for long distances, this is a horrible defect. The exhaust manifold has become loud, which means another expense on a 2005 which shouldn't be happening.

The contact owns a 2005 Chevrolet Trailblazer. Whenever the contact started the vehicle, she noticed that the exhaust system was very loud. The vehicle was taken to a local mechanic shop and they stated that there was a crack in the exhaust manifold. The vehicle was also diagnosed by the dealer for the same failure. The contact did not notice any differences beforehand. The current mileage was 68,239 and failure mileage was 54,100.
