I've got a 2018 Silverado and mine started doing this at just over 40k miles! Of course it's over 3 years and 36k miles so no warranty for me. Has anyone found a fix for this yet? It's the most irritating thing in the world to hear the buttons clicking, changing songs, putting phone calls on hold, etc, etc. I'm not about to pay over $1k to have this fixed when it seems to me it is a known issue throughout the GM community. I doubt there would be a recall on it because it is not considered a safety issue, right?!
