IIRC the '13-14 C-Max had some software issues causing 12V system run-down, don't know if the Fusion was affected too.
Thanks for checking. I'm pretty sure the Fusion was 2017. Most of what I read online from others was for the C-Max, so it could be the C-Max having an issue, the C-Max being more popular, or C-Max people being more vocal.

I chalk it up to growing pains, but if it happens to a real customer, I worry about their impression.
