From what I have experienced on two WJ jeeps (I know yours is a late model WY) A whine from 50-80kph that progressively get louder over time is the front driveshaft. You chase your tail because it seems to come from the diff. In both cases it was the CV at the transfer case that over time wears and causes drivetrain noise. But I do not know how the new model jeeps are set up.
Either way a car fresh out of the factory shouldnt be making any noises
