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.

problem #1

Trailblazer 4WD

  • miles
Wiring harness burned up. Caused damage to control panel, dash, computer system. Entire vehicle gutted to replace wiring. A door panel was broken in process. Several rattles now exist. We were told there was no way of knowing if electrical problem would occur again. GM agreed for repurchase. However, they delayed procedure so that 0% financing can not apply. Also wanted us to pay out of pocket, buy back amount said we would be reimburced, but would not put it in writing.
