While driving down the baja peninsula my steering wheel began to vibrate and make strange noises. Shortly after I lost all power steering making navigation over the mountain roads extremely dangerous and hard. Once home in the us I contacted a local ford/mercury dealer and was told the recall had already been satisfied.
