Although my focus doesn't do this, I really can't believe people are defending this quirk as normal. Especially since most people who are having this issue are saying it lasts much longer than Ford's "3 minutes" and even when the doors are locked. I have never seen or heard of a car doing this before. Maybe 30 seconds to a 1 minute can be understandable, but longer than that? really? As mentioned before I am sure this will wear parts out faster if this happens for minutes nearly every time the car is started from sitting.
This is just straight up bad engineering.
