2012 sport stereo fried- what to do?

Hello everybody, been a long time since ive been on here. need to update my pics and mods. Aside from that i live in south dakota and there was recently a gnarly blizzard that dumped about 4 ft of snow in the black hills area where im at. A lot of moisture got tracked into my truck from the snow. Ever since when i try to turn the volume nob on my stereo my cd ejects. also my eject button doesnt work. Is this something i should take my truck to a dealer for or should i try something else? thanks

 

If you are under 36k miles, make the dealer fix it.

 

x3....I seen the snow on the news, better you then me.

 

Thanks for your input gentleman. Im sitting around 13500 miles so i will definitely get that taken in.
