No i have not. The difficulty is that when i scheduled a dealer visit two weeks in advanced that's usually when the problem was just on set. By the time the appointment is near or due the freaking issue disappeared. Ford service mode really requires any problem that must be persistent for at least 2 wks. Lately the brushing noise seemed to morphed into an annoying full car shattering and "mouse clicking", not very loud but audible enough to be distracting. if you have any idea plz let me know.
