The exact same part broke in the exact same way on my 14' last year. As I had under 50K miles on the car, it was under warranty. The steering wheel was definitely taken off as it was initially put back on at least one tooth off resulting in the steering wheel being off center. They fixed it immediately though. I could tell just by the feel that the whole "triangle" of buttons were all new and obviously came as all one piece. I've no problems with that or the other triangle of switches since.
2014 SXL, only mods are after market rims due to recall. Plenty on the list though!
