We're a Canon/Profoto family: five cameras, sixteen lenses, fifteen Profoto lights, too many modifiers.
I did see that (from a couple of different sources). However, we're waiting on an official statement from Canon before we publish information on this supposed phenomenon.
I talked to Bryan this morning, and he's never experienced AF issues in cold weather. So if it is a genuine issue, it might be an isolated one or possibly only an issue in extreme circumstances.
This report says it's when temperatures get below 0C, but I imagine it's got to be a super isolated incident. Johnathan's Polar Bear expedition was fairly extreme conditions, at -20C, to -30C for days. If it was common, you'd be hearing loud grumblings from us Canadians, as over a third of the year is sub 0C.

I spent a week in the U.P. at -15 C to -30 C using the camera every day for many hours, and never saw a problem. And have used it many days this winter at -15 deg C with no problem. In fact, there have been very few times I have used it since getting it last September that I have been able to use it above 0 deg C. I hope it is not going to be a future issue, because I would be in trouble.

I recognize that you (while wearing the administrative hat) have an obligation to wait for an official statement. However, for those not in a para-official capacity, it's a worthwhile topic to discuss, as billing a customer for a repair that ought to be free and ought to be covered under a proactive service bulletin is, in my opinion, a rather poor way to treat customers. I say this having replaced the transmission on my Ford Excursion with only 45k miles due to the failure of a plastic part; failure of that part was covered under warranty if the vehicle had a gas engine, but Ford felt the lower RPM of the diesel prevented the part from failing. Imagine the coincidence when a friend's diesel Ford Excursion failed the same part at 45k...
With lots and lots of due respect, one negative sampling does not make the issue 'isolated'.

I got one of the 'early' 1DX cameras in July 2012 and I've never experienced this autofocus problem with it. My recent polar bear trip was the most serious cold-weather test I've ever given it, and I got tack-sharp images the whole way through. So hopefully like Sean said it might be a rare phenomenon, my camera is okay.

Mine was a pre-release pre-order, and although I haven't used it extensively in sub-freezing temps, I have been out shooting eagles on a couple of occasions for a few <32 °F hours, and for several shorter periods when my kids were out playing in the snow. I experienced no AF issues on those occasions.
