I have heard of this problem with quite a few of these cars and Ford's advice is to keep an eye on the coolant level.
If it drops substantially it could be the problem you mention. Should be a recall in my view to prevent the problem in the first place. That would probably work out cheaper for Ford too but they seem to take the attitude of 'wait and see what happens'.
