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.

My vehicle started losing power and would shut down on me. I was driving and the vehicle lost all power and then stalled. Luckily I was able to get off the road and avoid an accident. Had to have the vehicle towed. Found out it was the clutch fan. Had it replaced and no problem since. I have read many complaints on this issue. This could have caused a serious accident.
