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.

2003 Chevrolet Trailblazer Owner Comments

problem #1

Sep 232011

Trailblazer LS 4.6L 6 cyl

  • Automatic transmission
  • 103,000 miles


Key was stuck and would not move dealer said I would have to tow it in and it was probably an ignition switch,well with a little reasearch and help from this site I determined that the problem was probably not the ignition switch.I called a local mobile auto locksmith he cut me a new key to factory specs but it still didnt work so he said the tumbler was probably bad from the key being so badly worn.He installed a new tumbler and keyed to the key he had just made and what do you know it works.The dealership would have charged me $130 just to hook their computer up to it to read a code that would not have been detected anyway and $130 an hour to install an ignition switch that I would not have needed.
