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.

I have a 2002 chev. Trailblazer and 2 weeks ago the speedometer went upside down- it is not telling me I am going over 100mph or it tells me im going 0-to nothing. The gauge is upside down and will cost over 500 to get if fixed this is a new vehicle I don't think this is fair- if it were a 95 model I wouldn't be surprised but how many vehicles loose a speedometer gauge over within a vehicle that new?
