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.

2003 Chevrolet Trailblazer Owner Comments

problem #1

Jan 012009

Trailblazer EXT 4.2L

  • Automatic transmission
  • 80,000 miles


First time starting for the day, my blazer shutters and sometimes cuts off.

No one can figure this out, and I don't want to pay someone $80 to look to see if they can figure it out. Some Chevy dealer should have heard about this before to tell me what's wrong. Funny thing is, if you turn the A/C on after 10 seconds the engine suddenly has no problem and it does a normal rev and idles down with no shuttering.
