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.

Trailblazer EXT LS 4.2L

  • Automatic transmission
  • 105,000 miles

I purchased my 2004 Chevy Trailblazer used with 105K miles. When I purchased this vehicle used in 6/13 my code reader showed a bad oxygen sensor. I took my Trailblazer to a local shop to have the oxygen sensor replaced, which cost several hundred dollars.
