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: Carrying the not-so-proud traditions of its 2002 predecessor, the 2003 has a handful of instrument panel malfunctions that can leave you guessing your speed, engine temperature or how much gas is left in the tank.

problem #2

Mar 052014

Trailblazer LS V6

  • Automatic transmission
  • 125,000 miles


I own a 2003 Chevrolet Trailblazer. While driving 25 mph, the contact heard a bumping noise when driving over an uneven surface. The dealer stated that the sway bar links, front end links, and the front stabilizer shaft were defective. The dealer repaired the vehicle. Approximately one year later, the failure reoccurred. The dealer stated that the sway bar links, front end links, and the front stabilizer shaft were defective again. The dealer repaired the vehicle. A year and a half later, the failure recurred with the same results.

This is a continuing problem that I have repaired 3 times in the last 3 years. this has to be a defect in Trailblazers. As I hear the sound from just about every Trailblazer I have seen on the roads. Next, the front ends will start causing crashes due to this problem.

Trailblazer LS 4.2L V6

I've noticed that there is an absence of greasable ball joints under the front end of my wife's 03 trailblazer. Could this be the culprit behind the popping and creaking noise we experience when turning or driving on rougher than smooth asphalt roads? Anyone else have this same problem?
