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: Carrying the not-so-proud traditions of its 2002 predecessor, the 2003 has a handful of instrument panel malfunctions that can leave you guessing your speed, engine temperature or how much gas is left in the tank.

Every time I crank my Traiblazer it starts ticking like I am carrying around a time bomb. Last night I was standing outside and heard this same noise, I turned to make sure my Trailblazer wasn't being stolen. What I found was another trailblazer coming down the road. What is this sound? I did take it in and was told it was normal. Now it is much louder and almost does it constantly. I know there is 2 out there doing it, are there more? The looks I am getting are starting to scare me. Please HELP.
