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.

Trailblazer EXT

  • Automatic transmission
  • miles


2003 Chevy trailblazer blew a few fuses so I could not start the vehicle (several times already), per dealer. Tachometer jumps around, radio gets hot, electrical lights turn off along with heater/cooler, rear lights replaced three times, hole in gas tank, drive line replaced, constant chirping/ticking noise (of course dealer does not hear). Purchased brand new and have way too many problems for a new vehicle. You asked for incident date....there are several. Will stick to Toyota's from now on....

Trailblazer EXT 4WD 8-cyl

  • Automatic transmission
  • 35,000 miles
Vehicle when placed in four wheel drive, does not engage front wheels and in fact does remain in only two-wheel drive. This creates a dangerous situation because on snowy roads particularly in rural areas, for example, the vehicle can become unsafe to drive.
