If it's what we're guessing, you do not need to worry about it. Your car will have the upgraded part.What is service soon? Pretty ambiguous....bad?
He likely has the HVBJB pending failure issue. Older cars had an under-performing High Voltage Battery Junction Box (basically a bunch of high powered relays). It can fail. Ford modified their software to detect imminent failure and if it does, then it displays Service Vehicle Soon and drastically reduces the maximum amount of power available in order to lessen the chances of the HVBJB actually failing, thereby leaving the vehicle drivable, but in a reduced state.
But the original HVBJBs have been replaced by more robust parts, so the likelihood of failure is very low (though as with all things, still not zero).
For you and a new car purchase, it's not a worry.
