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.

2004 GMC Sierra 2500 Owner Comments

problem #1

Dec 022007

Sierra 2500 4WD 8-cyl

  • Automatic transmission
  • 68,000 miles


The contact owns a 2004 GMC Sierra 2500. While attempting to place the vehicle in reverse, the gear automatically shifted into neutral, causing the vehicle to coast backwards. Two days later, while driving at an unknown speed, the vehicle automatically disengaged out of two wheel drive and shifted into neutral. The vehicle would not accelerate so the contact safely pulled off the road and waited two minutes. He then pressed the button on the transfer case to re-engage the 4 wheel drive. He took his vehicle to the dealer and they replaced the transfer case control module and motor. There had been no further occurrences. The contact filed a complaint with the manufacturer. The failure mileage was 68,000 and current mileage was 68,268.
