This has happened to me in my 2022 Silverado TB. It’s happened like 5-6 times in the past year. Took it in twice for it and just get told it’s an update. I find that hard to believe and should not have to constantly take it in or worry about it. Definitely a safety issue and could cause a wreck or if you have newborn baby in the vehicle and volume goes to max. Mute or power button does nothing. I had to scramble to grab my phone and switch over to Apple Music and start and pause a song.
