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.

CarComplaints.com 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.

For a vehicle that is only 18 months old, I had to replace the passenger side headlamp 4 times already. Yet no one agrees that there could possibly be a short in the electrical system causing the problem. I can't see 4 different sets of bulb being bad.

problem #5

Trailblazer 4WD 6-cyl

  • 10,000 miles
Engine stall - truck stalled and all lighting and components went dead while slow to stop at an intersection. The truck could not be re-started. After 10 minutes, the truck started again and was able to drive on. Subsequent attempts to start the truck failed resulting in it being towed to the dealer. The dealer had to replace one of the computers in the truck and it has been fine ever since. I heard about the investigation for the Envoy and Bravada but not the Trailblazer. My truck is a Trailblazer and did experience the same problems as the two sister trucks that share the same mechanicals.
