After downshifting to 2nd gear and coming to a stop at red light, I accelerated with the green light not realizing the F10 was still in 2nd. As I ramped up and heard the high revs, at the same time my car went into a reduced power or Failsafe mode, and the warning message appeared that the power train had malfunctioned. At this point my F10 sounded like it was mis-timed and hesitated badly. I drove slowly in this condition for about a minute, then all by itself everything returned to normal full power!

I thought the rev limiter was supposed to cut in well before any automatic default to a low power setting and an associated warning.
Might be worth a call to your dealer.

Take it in for service and the dealer can read the computer and see what the issue is.

Absolutely no need to take a 2011 car in for a service. Apart from the fact that it would be unscheduled, unnecessary and at customer request, the OP would be charged for it.
If there's a fault and, as the rev limiter didn't appear to have cut in, I suspect there might be - this is a simple warranty investigation.

Pretty sure that's what he meant by service. Not "normal scheduled maintenance service" but "fix it under warranty" service.
