Well, you know what they say about "first year cars".
Honestly it could be anything though, with all the electronic systems in today's cars, even the best of them occaisionally get a "ghost" in the system, or react to some unseen outside force.
My Dodge did exactly what you described to me, exactly once, never could duplicate it. I punched it from a light, about 10 yards later it lurched, died, and didn't want to start. Got out, opened the hood, made sure everything looked allright, turned the key three times to get a list of codes, got three, turned it again to start it, light went out on it's own, and when I got to the shop and put the Mopar scantool on it? No codes, no history, no nothing, and it never did it again. I was a freaking Chrysler/Jeep tech at the time, had access to everything in Mopar's database, and couldn't find the cause, couldn't duplicate it.
I've seen other equally weird things in the four different dealerships I've worked in. I've seen a radar detecter set off the entire TPMS system in one, I've seen a power inverter cause a drive-by-wire system to go to limp home mode, I've seen someone throw something in the microwave in the break room and watched all the sensor data go crazy on a car that was being scanned with a scantool.
Hopefully Ford figures out what happened here, but honestly, there's a real chance they won't be able to duplicate it.
