PCM problem yesterday -weird high pitched squealing
Yesterday while driving in my 2023 cab at around 50 mph, heard high pitched squealing audio sound from the dash. Thinking it was from the outside I muted the radio and it was coming from the PCM screen. A moment later, PCM shut down and rebooted itself and I did not have any issues rest of the day or today. This is an issue which I can guarantee will never be replicated at the dealer ! Anyone have a similar issue ?

Never had that specific issue, but I do get fairly persistent issues with the built in Spotify app that requires a reboot to fix. If it happens again, follow the instructions on thread below to reboot the PCM and see if that doesn't resolve your issues.

I haven't run into this exact problem before, but based on what you're saying, it could be a good idea to see if any error codes popped up during that musical moment. Sometimes these things leave a mark, even if they don't happen again.
