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.

Ignition switch failed while driving on a busy street which caused the engine to stop immediately. Vehicle was towed to dealership with a suspicion of a dead battery by the consumer. After examination by mechanic it was revealed that the ignition switch was left on when suddenly all doors automatically locked. Center console was dismantled and a cable attached to a solenoid had to be pulled to release the shift lever to open the door. Ignition switch was replaced.
