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.

Print this page 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.

Trailblazer 6-cyl

Consumer states passenger's side seat belt fits too tightly, passenger unable to move. Dealer replaced seat, but problem was not resolved. Dealer brought in a 2003 Trailblazer. The seat belts did the same thing. The height of the seat belt isn't adjustable and cuts across your throat, depending on you size (driver and passenger side). Consumer had to purchase special seat belt adjusters to make the belts wearable and more importantly-safe. Consumer had recently discovered the tightness of the rear seat belts.
