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.

Sierra 2500 6-cyl

First the transmission cooling lines rusted out costing over $400 to repair. Today the brake lines failed because of rust. This will be a very expensive repair. I was fortunate that I was able to avoid crashing the truck when the brakes failed.
