Just bought a 2021 M3LR and having same issue. Notice it glitches when radio is loud. Almost like the vibrations make it glitch. When I hold screen and press it towards me to prevent it from vibrating it stops. As soon as I release, it starts back up. Worst part is that screen automatically selects features like songs, opens apps, changes HVAC settings, opens locations ok Navigation system because the vibrations make it think someone is selecting these features. I have maintenance coming down in a week. Hoping to get this resolved.
