2017 Genesis G80 electrical system problems

The car randomly does not turn on when I press the start button. Nothing happens. It's not the key fob either because absolutely nothing works in the car at that point. I can't open the trunk using the button inside the car, lock or unlock the doors, nothing. The car is essentially a useless hunk of metal. After about 15-20 minutes though, the car will just randomly turn on. I don't press the start button - it'll just turn on. This has happened on 3 separate occasions so far.
