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 #3

Trailblazer LX

  • Automatic transmission
  • 70,000 miles


This has become a permanent problem occurring over and over again no matter how many times I have these lights replaced it keeps happening.

problem #2

Jul 012008

Trailblazer LT V6

  • Automatic transmission
  • 72,000 miles

This repair was required immediately after another repair was done to the rear tail lights due to a GM recall notice. GM has said the two problems are completely unrelated. However, due to the proximity of the electrical wiring, in addition to the time proximity of the two events, it's not clear to me this is really the case.

problem #1

Apr 042005

Trailblazer LT 3.2L V6

  • Automatic transmission
  • 6,000 miles

Headlamps and Taillights must be replaced about every 6 months. The dealership says there is nothing they can do. The lights were covered while under warranty, but now I have to buy them and replace them myself.
