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.

  • 32,000 miles


- the contact stated that while driving the 2005 GMC Envoy with 32000 failure mileage at 35 mph on many different occasions the vehicle switched into 4 wheel drive on its own and slowed the vehicle down in the process. The contact kept control of the vehicle and pulled it onto the side of the road. The vehicle was towed and repaired on several occasions, but nothing seemed to resolve the problem. The current mileage was 41000.
