You need to check a couple of places, some have been listed, but there is one not mentioned and is a common leak point. And a minor fix!

On the passenger side of the engine at the front, there is a lower radiator hose, in it is a sensor. The O-Ring fails and it could be leaking from there. The fact that yours is not coming out rapidly lends itself to a smaller leak point. If you take it to the dealer they will replace the entire hose and sensor for several hundred. But you can just buy an O-Ring from Home Depot and fix yourself.
