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.

The contact owns a 2002 Chevrolet Trailblazer. The contact was underneath the vehicle trying to remove the spare tire, but was unable to raise his vehicle to the proper level. He believes the failure to be a manufacturer defect because the tire is the original tire that came with the vehicle. As a result, the contact believes that the manufacturer should be responsible for the vehicle to be raised to a proper level to remove the spare tire. The current and failure mileages were 28,400.
