I would goto the dealer and INSIST they look it over for free because its a potentially life threatening issue you have there. and see what they say, maybe a call to BMWNA after they look at it will shed some light for you.
P.S. My car will drive itself through parking lots @ about 25mph without me doing anything but tapping the brakes twice real fast lol
any brake tapping prior to this happening?

Should I call BMWNA first before going to the dealer?
What do you mean tapping the brake twice, is that to reset something to the computer?
Thanks
