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.

2004 Chevrolet Trailblazer Owner Comments

problem #1

Aug 132009

Trailblazer LT EXT V8

  • Automatic transmission
  • 68,979 miles


Glad for the extended warranty. Have had all kinds of expensive to fix problems to fix! Many such as the tailgate spoiler were because of poor design.

Update from Aug 9, 2011: because of the bar that the the spoiler is attached to the rear glass window, not only did the spoiler have to be replaced but the rear window also had to be replaced and that really drove the price up to over $900.00. Now here it is 2 years later and the same problem has occured with the bolt breaking that holds it to the chassis. This time the estimate is around $1700.00 because not only will the spoiler have to be replaced but the rear glass must also be replaced. Am I in for it again in another 2 years. The chevy dealer said they were sorry and that they had fixed several other 2004 ext trailblazers with the same problem and that GMAC doesn't help out with it.
