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.

Trailblazer LS 4.2L 6 cyl

  • Automatic transmission
  • 142,000 miles

this problem also has the service engine soon light on, tune up has been done. has anyone else had this problem? also had transmission overhauled, replaced an overpriced electronic fan clutch, plus interior trim pieces falling off. I'm a big gm fan but wouldn't own another damn trailblazer as long as i live.
