Buttons for audio/clock don't work
 

I just got a 2010 Mazda 6 and the button to change the minutes and a button for the audio system (pushing in the button for tuning the radio doesn't work, but twisting it does) just don't do anything when they are clicked. I was wondering if anyone has heard of this happening to other people and if so, is there any easy fix or something I can do to troubleshoot? It seems odd that this would happen on multiple unrelated buttons, the minutes one being especially odd as it wouldn't make sense to be damaged from overuse.
