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.

problem #2

Dec 012009

Trailblazer EXT

  • 43,600 miles


4WD quit working and was told by the dealership today I needed to replace the transfer case for over $2,000. Already reported the fuel sensor quit working. Told by a phone rep for NHTSA it could take at least a year to investigate and was given a phone number for the ftc. My car has under 44,000 and when the transfer case went it there was a smell of smoke.

Trailblazer EXT 4WD 6-cyl

  • Automatic transmission
  • 22,430 miles
While driving, the vehicle would shift from 2wheel drive down to 4 low, causing a very rapid decrease in speed and loss of control over vehicle, depending on driving speeds and rd conditions this could cause a very dangerous accident. I have had the vehicle into the dealer 4 times in the last month and they have replaced, 4wheel drive switch on dash, encoder motor on transfer case and reprogrammed stabiltrac, vehicle is still at dealer and trying to solve problem. Dealer has been very polite and understanding during this entire process.
