Take back to dealer and get it reset they caused problems and should fix it free

Im not sure if your fuse box looks like the screenshot however if it does I would at your own risk turn this switch off and back on as suggested in the other photo.
Again I am not a mechanic, I do however try to give the best advice I can.
Hope this helps.

Does this have blue tooth ? The last update Hyundai sent out has done this to some vehicles easy fix if I have all info
