I am in the same boat as you. 2020 Ford Fusion Energi. Not in the program. Still under factory warranty.
I spoke with my dealer about my options.
Part $318 + tax
Labor $120
PROBLEM!!! Ford is advising to NOT install this in 2020 vehicle outside the Customer Satisfaction Bulletin due to connectivity and software issues.
He told me they can install it but when they try to update they may brick(Freeze) the software on your car and not be able to get it back to normal.
He figures ford is still trying to figure how to make all the software jive in the newer cars and there may be a later customer satisfaction program again.
