If you park it with the climate control set on defog it will do this. The condensation is from water evaporating out of the airbox under the dash and condensing on the windshield. It usually happens if you are driving on a wet day then park on a flat or slightly incline. The water can't drain out of the box.
The easiest way to prevent this is to turn the clime control to off before shutting off the car when you are driving in the rain.
