So here we are January 2018 and I hear I need a new upper and lower hose and a mysterious T connector..

There is a national back order Till January 16th, Today I hear the back order is now February 16th..No after market part available for this fix. This seems to indicate these are failing all over the country and there is high demand. (my car place has two of these in the shop right now)

Come on Ford, hose going out at this low mileage is not normal.

There seems to be a problem with the hose construction, the proprietary design approach or maybe the coolant or your forecast of the expected fail rates of these components is way wrong...??

I also see the same thing reported Jan 2017...a year ago..??
