Can't you just take a garden hose and spray the hood until the ice comes out or melts, kind of like a person does to a frozen windshield?
I take it you don't have a garage.
Since it is a leased vehicle, turn it in and get one that has a normal hood. You probably won't have too much trouble doing this due to the reason you are wanting to exchange it.
