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's side seat belt will continuously tighten up after it is buckled. Manufacturer claims that this is the way the belt is designed for the use with child safety seats.

Front passenger window shattered for no apparent reason-heard a pop, and the entire window shattered. For the rear seatbelts, the inertia locks activate and the belts lock up too easily, trapping the passenger in the seat. To release the belt, it must be completely removed and reattached. Dealer claims this is normal operation, due to child seat safety design. But this design seems dangerous to the adult or grown children as passengers.

Seat belt locks properly on brake application then will not release and continues to tighten on passenger, to the point where passenger refuse to wear the belt. One replacement belt fail to lock up at all. Have been told by dealer and Chevrolet that child restrain in belt is causing problem. Child restrain is only operational if belt pulled out all the way which is not the case.

Problem #1: passenger side seat belt will lock up and not release until buckle release is pushed. The seat belt tightens so that passenger cannot even make small movements, like opening the glovebox or operating the radio. This is a saftey hazard as the seat belt is particularirly restricting to my pregnant wife. To release the belt by releasing the buckle would be unsafe while the vehicle is moving. Barton birks Chevrolet dealer says belt is of "normal operation as per make and model design". driver side seat belt has no such problem however. Problem #2: driver and passeger side power mirrors will change their positions at random. This is another saftey hazard because often you will not notice that the mirriors have changed their positions on their own until you need them to perform a lane change. Mirrors out of alignment are increasing the"blind spot". to realign mirrors when driving is also distraction, all of which could result in an increased risk of collision. Barton birks dealer says "could not duplicate customer concern".
