2017 Tahoe. My Infotainment system is going crazy. It’s as if there is a toddler inside it randomly pushing buttons. It will turn itself on, switch from app to app, put a call on hold, call someone, switch to navigate, try to navigate to a random non-existent location, switch back to Pandora and shudder and jump from playlist to playlist, interrupting songs. It doesn’t always happen, but is getting more frequent and once it starts, all you can do is turn the vehicle off. I called my dealer but didn’t get any intel over the phone. Fixable? Expensive?
