    It is a humming noise and seems to be coming from the general area of the hybrid plug midway under the car. Occurs randomly long after the car is turned off. Any ideas?

    That's normal. Your car's checking for fuel leaks.

    Is it 5 hours after you turn off the vehicle? Page 22 of the Owner's Manual:
