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.

Trailblazer LX

  • Automatic transmission
  • 78,000 miles


As soon as I hit 50000 miles on the car, the fan clutch started acting up. When I started the car it sounded like a jet engine taking off. To go from stop to start it, again, sounded like the jet engine it acted slugglishly. The car lots of gas. My mechanic replace the fan clutch. A year later I had to replace the fan clutch again and a year later it is due for another. GM knew about the fan clutch problem, claimed it was a factory defect and refused to issue a recall. The only recall that has been issued for the Trailblazer was for a faulty latch on the glove box. Sure, GM, go for the cheap fix! It doesn't surprise me that GM has had financial troubles, they could care less about the customer who buys their vehicles. If you don't treat your customer right, they will go elsewhere.

the ntsb must look into this because if the rpm is high at number as soon as you turn on the ignition it may cause the vehicle to move at a high rate of speed.
