I've had the dreaded red lights come on a couple of times, both times not that long after carefully (i.e. with low hose pressure) washing the bike - no recurrence recently, but am not entirely confident I won't ever have to pedal it unassisted a very long way one day, and I have a dirty bike now too.
My mate who hoses his S-Works down after every ride had a total power failure when it was only a week old, and so had the take it back 250 km to the LBS who replaced all the cables one by one until it worked again - it turned out to be the speed sensor cable that was the culprit, and I suspect water ingress is the prime suspect in this case as well.
