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 #2

Sep 052006

Trailblazer 6-cyl

  • Automatic transmission
  • 35,000 miles


The panel for the power seat controls on the driver's seat is designed such that it is broken loose easily by simply entering and exiting the vehicle. It's design and mounting location causes it to have to support the weight of the driver as he enters or exits the vehicle. Once the mounting supports break, the controls are only supported by the wiring.

While driving approximately 10 mph, the driver's seat suddenly lowered to the right while making a right turn. The consumer broke one of his right ribs in the process of the seat collapsing. The steering wheel did not return to the normal position after making the turn. The cause of the failure had not been determined.
