sorry to necro this, but i just had the same thing happen to my 2017!!!!
your picture is shows the same thing, the rubber it self is completely fried, and sort of a burnt dome on the inside of the rubber cap. the copper terminal looks pretty burnt too..
i took the alt off and if i give it a shake you can hear something rattling around inside. im going to replace the alt, but at aprox $250 per i don't want this to keep happening if the alt is not the cause..
im probably going to upgrade the alt positives wire too while im at it, do the two leads going from the Alt to the fuse box and then to the starter.
did you ever find out what the source was for ur burnt terminal/alternator? did you have issues after?
