My 2013 C-Max SE has the exact same repeted dead battery issue. First time the car was found dead it had 1300 miles on it. At the Ford Service Dept , no issue/problem could be found. Now it has gone dead mysteriously twice in a week ( now has 11000 mi). The third time it was found dead it was towed to the Ford Authorized Service Dept without being jump started. It was plugged into the computer and no error messages were found. The car is dead in the service bay and the diagostic computer is showing no problems.The Ford Co "regional customer service manager" has not returned my calls for over a week. My region is New England.I have found.other C-Max owners in the north east who have taken to carrying jumper boxes in the cars due to the same issue. The car handles well and I'm satisfied with the milage. But as a previous poster wrote, if it's unreliable its worthless. Looking into Lemon Laws
