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.

Sonoma LS 2.2L

  • Manual transmission
  • 14,995 miles


I purchased my GMC sonoma Oct 2003 with 8miles on it!!! It was a great truck till Feb 2005 @ 14,995 Miles....I was driving from SE Georgia to Jacksonville, Florida Airport approx. 85Mile trip. As soon as i hit the FL/GA state line I noticed the windshield becoming very blurry. I take a look at my gauges, everything was fine....Then all of a sudden I hear a bang and my check gauge light goes ON.....i pull to the side of the freeway and open the hood discovering my FAN & Fan shroud, a piece of pipe (atop the water pump) was missing, AC compressor, Radiator. AC condenser, belt, and Intake Pipe were all damaged!!...Same problem appeared again in Aug 2006, this time in Sacramento, CA....After the vehicle was repaired under warranty...I sold it with 22,000 Miles on it....Ill never buy GM again!!!Back to Toyota I go.......
