Lose Power Steering problems of the 2014 Ford C-max

1st incident the vehicle completely died while I was doing 50mph down a 5 lane road. All electrical went out while I was driving. Lost my power steering and braking was extremely difficult. Had to have the vehicle towed as it would not re-start. 2nd time about two weeks after getting the car "fixed" the vehicle died while I was driving on i75 with same scenario. I was able to pull over on shoulder and had to have the vehicle towed in. 3rd time after getting the "fixed" vehicle back the radio went out, then the clock went wacky, the check engine light came on and when off. Then while running errands the car simply did not restart. No power to the dash, locks, etc. Had to have it towed in. Took the vehicle back again and the 4th time after driving an 1 1/2 hours to work the vehicle would not restart without being jump started. I had it towed to the dealer again and they cannot find anything wrong with it and I am being forced to take back a brand new 2014 Ford cmax energi with 4400 miles on it that keeps dying every week. I do not feel safe nor do I want the vehicle any longer. Ford has not yet sent any special assistance to the dealer to help rectify the problem.
