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 Trailblazer emerged from an "upscale trim line" of the Blazer, but there's nothing upscale about its transmission problems or its wonky, unpredictable headlights.

Metal plate with all of the connections to the plastic gas tank rotted away, causing fuel vapors to enter the vehicle. We only have 38,000 miles on the truck. Tank design will hold mud and water in a depression on the top of the fuel tank, promoting rust holes, that not only allowed vapors to escape also leaked gas when the tank was filled.

The fuel tank filler neck detached from the tank. As a result, when filling the vehicle with fuel it poured out onto the ground.
