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

Nov 302007

Trailblazer 4.2L

  • Automatic transmission
  • 62,000 miles


fuel sending unit went out on us, replaced the sending unit, my helper dropped the tank and i had to purchase a tank from the bone yard $520 for the pair, then after i retought the computer from having the battery disconnected it started to surge and backfire a week after the installation. check engine light came on, the only known fault code listed was for a corroded tank pressure sensor. the car only surges and backfires occasionaly it is also shifting strange when this happens. my wife says on two occasions that after a long drive the car will not restart after sitting for a short period of time, give it 15 mins and it will start right up,, oh yea and we too have the ticking issue.
