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.

2004 Chevrolet Trailblazer Owner Comments

problem #1

Jan 022004

Trailblazer 6-cyl

  • Automatic transmission
  • 100 miles


2004 Trailblazer has 40 second turn on of headlights and back up lights when remote key used to unlock doors. This has on 2 occasions has caused vehicles in travel lanes to suddenly brake because with the back up lights on Blazer appears to be backing into traffic. Solution: Only occurs after dark, so must be relayed thru daylight running detector. Needs to do as brake and turn signals do, flash on and then off. Headlights have stayed on shining into a group who threaten me with bodily harm. Dealer said a GM problem, they can't change. Had 2002,2001,1998 Blazer, never a problem.
