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: The Trailblazer emerged from an "upscale trim line" of the Blazer, but there's nothing upscale about its transmission problems or its wonky, unpredictable headlights.

2002 Chevrolet Trailblazer Owner Comments

problem #1

Jan 152016

Trailblazer LS 4.2L V6

  • Automatic transmission
  • 181,000 miles


I was attempting to brake while in moderately heavy freeway traffic at 60 MPH. The car began slowing and then suddenly accelerated rapidly. I managed to shift into neutral, while furiously stomping on the brakes, and stopped just inches behind the vehicle standing in front of me. The Trailblazer is working fine now, no re-occurrences, yet, but I'm worried about the "next time ". Is this a recall issue? I need this fixed ASAP. What's my best move? Take it to my trusted mechanic and hope he can fix it? Ask GM about this? Thanks for your help.
