Does anyone know part number for up and down button next to Menu and Home buttons for infotainment system? I have MY14. Mine is starting to fail, down button feels mushy in the beginning but now I can barely click. Funny this starts to happen right after 4 yr warranty is up. I will probably have to replace the whole button assembly including Menu and Home buttons but I hope I won't have to buy the whole arm rest.

I'm pretty sure it's 84782-53040 and you're looking at over $1000 USD. Hopefully you can find one used or buy the extended warranty.

 

Holy hell $1k for just the part with a few buttons? I'll take it apart and maybe blow some compress air into it to see if the button click improves.

 

You can't just buy or replace the button. You will need to buy the whole cup holder and control piece. You can find the part number and item in the link below. It doesn't cost 1000 dollar, so don;t worry about it. Most i would pay is 200 and it's very easy to install that piece yourself.
