2015 MKC when accelerating with traffic and when crossing traffic my car lost all power and the dash board when blank. After a few seconds (which seems like a long time when cars are coming at you) the power came back and part of the dashboard disappeared. The dealer said was a software update. Took the car in and it has happened again since I have gotten the car back. Seems like a safety concern to me and I'm fearful of driving the vehicle.
