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.

While decelerating, either braking or coasting, the car will lurch violently when reaching approximately 22 mph. The severity of the lurch varies but in most instances it is hard enough to snap my neck forward.

The cruise control is inoperative. The cruise control light will come on, but you cannot "set" the cruise control. I have read online about several other Kia makes and models having this same issue. As far as I can research, there is not a fuse for the cruise control.
