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.

The passenger seat belt retractor is designed to lock and not release if the shoulder belt is pulled all the way out. This creates a saftey hazard. If the passenger has to reach for something that casuses the shoulder belt to extend completly, you then have to unbuckle the seat belt, retract it, then rebuckle the belt. If this occurs while the car is in motion, the passenger is open to injury should an impact occur at the time the belt is unbuckled. If the belt is not unbuckled to release the retractor, it is extrememly uncomfortable to sit in the seat as the belt will prevent any forward movement. I believe this to be a flaw in the design of the seat belt and not a feature as General Motors describes it. This occurs on any GM seat where the belt is integrated with the seat rather than mounted to the framework of the car.
