On 9-27-14, using adaptive cruise control on straight, 4-lane divided highway with no traffic in lane ahead or behind. vehicle's brakes suddenly activated dropping speed from 74 to 50 mph. taken to dealership 10-7-14 and issue could not be duplicated. happened again on 11-11-14 with same roadway & traffic conditions, this time 55 to 50 mph drop. taken to dealer on 11-20-14 and again no issues were detected with the vehicle. contacted ford customer service who said to take it back again to generate a "hot line" complaint for an engineer to look at the vehicle. took vehicle back 12-3-14 and left it so they could drive it for a few days and try to duplicate the issue (they supplied a rental). called after 2 days and said an engineer "happened to be there looking at another vehicle so they looked at mine". no issue found, but they did a reset of the system. the entire time they had the vehicle, it was driven a total 6 (six) miles. also, adaptive cruise is set as a default and cannot be changed. if you turn the "adaptive" feature off, it goes back when you start the vehicle again. *tr
