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.

Well - poor idling left me worried - which led to the check engine light coming on which made me worried which left me getting it diagnosed which made me worried which led to them finding a bad coil which solved the problem - for about 6 months when another one went or was starting to go - I ditched the piece and traded it in for a vehicle with a great full warranty... crap really... if you have to replace one replace them all but i'll tell ya - they aren't cheap. Chevy really let me down. Misfiring and down a cyl. also your check engine light will start blinking
