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 #1

Sierra 3500 5

  • Automatic transmission
  • 55,000 miles


If this situation happened at freeway speeds, there would have been fatalities. I had this truck into the shop just before to have the tires balanced and rotated and brakes inspected. When I did a light lite on my panel for a brake issue, it was already too late. I have experience downshifting and handling loads. I drove in the ditch to slow the truck down and used a trees and rocks to finally stop the truck.

I know that GM is under pressure to recall these trucks and they should be. If the front lines were separated from the back lines then at least there would be front or rear brakes. It is a design flaw in more than one way. The brake lines should not lay on top of the frame where dirt, snow, ice and salt sit and rust these away. This is a perfect condition for problems, it is not easy to see that the brake lines are rusted. Just that area is rusted. GM knows this is a problem. The truck had less than 55,000 miles! It is still the old GM. There is no change.
