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.

Blazer 4WD 6-cyl

  • Automatic transmission
  • 3,222 miles
While driving at 65 mph the the service engine light and emergency brake light came on. Then the odometer and speedometer stopped working. When I stopped at a stop sign it was almost impossible to get the vehicle to accelerate. Pushing the accelerator pedal just caused the engine to race. This is the second time this has occurred. It first occured on May 20, 2004. The car was towed to a dealer who could find no problem.
