I realized after a few weeks of using the C-Max that the Value Charge/Charge Now setting on the car was “global” (See this post). In short: The setting wouldn’t change when switching profiles.
Last week I had the car in for its first oil change and a few recalls. One of the recalls did involve reprogramming the telematics module. Over the next few days I noticed that the charge setting would switch when the profiles changed..! After watching the screens change as it switches profiles it would appear that when they reprogrammed the telematics module they fixed the value charge/charge now switch–its no longer global.
Finally now I can use it the way it was meant to be used.
