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 1500 8-cyl

While driving the vehicle at a rate of 20 mph and started stopping and notice the brakes where going out. I had then lost brake pressure altogether. Used the parking brake to get stopped after putting the vehicle into neutral. I had the truck towed to my local independent mechanic and he checked the vehicle and found all the brake lines to be rusted out, and had lost all brake fluid. Upon finding this he found the majority of the undercarriage to have severe rust damage an several parts also.

This is a constant and ongoing issue with the vehicle. When driving the vehicle on the highway or road at speeds above 15 or 20 mph the front suspension will shake violently when hitting bridge expansions, any sort of road bump, man hole covers with minimal edges, etc. The violent shaking in the suspension will then stop and not be felt during normal smooth highway or road travel but recurs each and every time road bumps are encountered. The shaking is violent and feels as though the whole front end of the vehicle is about to fall off. This has been happening for more than a year now. I have had the vehicle examined by the dealer and independent shops and they all say the suspension components all look intact and in good service condition.

The contact owns a 2007 GMC Sierra 1500. When the pavement was wet, the vehicle would begin to fishtail and aggressively turn 180 degrees. The dealer stated that nothing could be done unless the pavement was wet. They gave her the option to trade in the vehicle for a different vehicle, but she declined. The dealer then advised her to look in her owner's manual and call NHTSA. She stated that the dealer would not even keep the vehicle to inspect. The failure mileage was 12 and current mileage was 11,000.
