Hi!
2 weeks ago noticed on my MS 2018, that voice command button not working, same common problem - opening driver door and pressing horn activates voice command, but not the right button. Took out airbag module, checked both buttons modules and wires that goes from right to left module. Voice commad switch was in perfect shape and worked well. This voice command switch connects to the eart(negative), when you press it. The other end goes from right buttons module to left and connects straight to STM32F microcontroller. So the problem must be software!? Many people telling, that they think that problem started after software update - now I think, it's very possible. Found today exploded airbag module with buttons set, replaced my LEFT buttons module, and voila - voice command button is working again! I hope, the future software updates don't kill it again!
Long story short - hope that information helps somebody!
