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

Oct 062006

Trailblazer LT EXT 4.2L 6 cyl

  • Automatic transmission
  • 43,000 miles


Ever since I bought my TrailBlazer in '06 I've heard this annoying whine at low speeds. It may make it at higher ones too, if so the road noise is drowning it out. It doesn't seem to get any worse. I figured it was the transmission, since it's only heard when the car is moving, but when I got a leak in the power steering system I found the whine from the power steering pump was exactly the same. I'm guessing that replacing the power steering pump will eliminate this noise, but I'm not sure.

I really don't like that noise, but I'm not going to put money into it either. If it aint broke I aint gonna fix it.
