2014 Ford Fusion stability control problems

I avoided another vehicle that cut me off on the expressway by honking the horn, slamming on the brakes and quickly changing lanes. As soon as I maneuvered into an empty lane, my vehicles instrument panel went dark, the horn stopped sounding, all gauges went to zero and the car lost all electric power (including steering assist) and the engine stumbled. After a second or two everything on the instrument panel reset.

I pulled out of my driveway and decided to check my mail. I drove up onto the curb to access my mailbox. As I was about to pull away a vehicle approached causing me to suddenly stop as the wheel was descending the curb. Warning lights flashed & bells sounded. I received messages that my advancetrac had failed & that the hillside assist had failed. I now have 2 warning lights still illuminated on my dash regarding traction control. The power steering is not longer functional.
