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

Feb 182013

Trailblazer LS 2.5L

  • Automatic transmission
  • 162,000 miles


All the dashboard lights came on. All the gauges dropped. As I was driving the highway all electrical slowly died (the radio even shutdown). I arrived home and turned off the truck and it would not restart. Had to jump it to get it to the dealer. This has been an ongoing problem but the dealer has no clue how to fix it.
