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: It would be ill-advised to blaze any trails with the 2004 Trailblazer. Its faulty fuel gauge could leave you stranded.

On 4 separate occasions vehicle stalled. When this occurred consumer tried to restart vehicle, but it wouldn't restart. Also, keys were stuck in the ignition. As a result, battery was drained. Dealership has replaced automatic transmission shift lock control, battery fuses, programmed the calibration for the engine control module, the starter, and its relay switch.
