The blank button under the mode selection and to the right of the scroll on the left side of the steering wheel fell out and is lost. I need to get a replacement, but I do not know what part it is. The dealership is trying to get me to pay $800 to replace all of the buttons. Can anyone help?

 

Hi ,
I have the same model vehicle and I am also looking for the same button replacement. Did you eventually get you replacement sorted? Just curious as yours is the only entry on the wide web about the issue. Any suggestions would be appreciated .
Thanks in advance
