Sounds like your usbc board needs replacing. I suggest booking it in and kicking up a fuss for a free replacement. Fortunately on your model they have made the board replaceable and not part of the main logic board.
Aw fs. Edit its actually a 2017 and still has to get the keyboard replaced under there warranty thing.
