I got my car back after the 2nd time in Ford Service for dead battery issue. They kept the car a few extra days to make sure the same thing didn't happen to them. Thank you Russael for your information regarding a possible short in the wiring of the high voltage battery fans. The first time my car died it was as dead as greyghost88's wife's car and that freaked me out. I didn't even KNOW about the hidden key, thank goodness the guy from AAA did! I highly recommend taking (or towing) your vehicle to Ford Service to have it checked. Ford Roadside Assistance towed my car both times at no cost to me. Each time they have replaced the 12-volt battery and performed "updates". Also, an official record of issues is being compiled in case we need it later. I like driving new cars because I am relatively certain that when I get in it to go somewhere it will RUN. So far, so good after this last trip to Ford Service. I will keep you posted.
