Yep. Same here. I have a late-March 2019 MX P100D. A couple of weeks ago, I experienced similar symptoms as ysquared2 illustrated. For me, it started when I received a call while media was playing from my phone. I took the call and hung up, but my music didn't re-start. I just heard static. I, too, was in full autopilot. I thought that was odd, but figured I needed to re-boot my phone (thinking it was the phone causing the problem since I'd also just received a call). A reboot of my phone didn't solve the issue, then slowly other on-screen systems started to fail -- my directionals didn't make the clicking sound, or flash when I changed lanes, then the arrow showing my position on the nav screen froze. I shrugged, rebooted the screens while driving and was impressed that I could continue to drive normally while the car's systems started coming back online. After the reboot, all was great.
I'd have totally panicked if I hadn't read a few posts in this forum about how to reboot if issues arise, so THANK YOU to everyone for posting your experiences. I'm on an old-ish SW version: 2019.5.17 3af66e8 and haven't had a reliable-enough nighttime WiFi connection to upgrade.
