MFD and Steering Wheel Buttons Stopped Working

2012 Plug In. My wife was driving to work and the radio/MFD just went dark. I checked fuses but did not find any blown. That was two weeks ago. The other day I tried to press the trip/odometer button on the steering wheel but nothing happened. The horn works. The cruise control works. No other warning lights or issues that I can find. I had been thinking I needed to replace the MFD but now, I am wondering if that is good and it is something else. Could it be the clock spring?
