I can't say for sure being that I haven't had a chance to take apart a 2011-up steering wheel but I don't think they're tied into the clock spring.
Check for loose fuses first. Then check any aftermarket wiring tied into anywhere around the column. After that, you'll just have to check for loose connectors, etc. Did anyone work in that area recently?
It could be your cruse control button as that provides power to the rest of the steering wheel controls as well as it could be the clock spring ribbon cable.
