Kia forte 2014 steering wheel functions don't work

What is your question?

I have a 2014 Kia Forte whose steering wheel functions (answering calls, ending calls, volume, channel changing, basically all the buttons on the steering wheel) stopped working. The fuses are all good to go. I read an article about it possibly being the clockspring, but before I send it to a professional, what else should I check for? No noises from the wheel or the car itself or leaks. I've taken as good care as I possibly could for it.

What makes this problem better or worse?

N/A

How long has your 2014 Kia Forte had this problem?

Two years
