Radio Completely Dead
Started my car earlier and the radio wouldn't play anything. No radio, no XM, no phone streaming. Nothing at all would play. Drove for 20 mins, turned off car, started an hour later everything worked fine. Anyone encounter this?

I had something kind of like this. Was one of my Modules. Was kind of a pain to figure out, GM made my dealer try a bunch of software resets and they eventually ended up changing the module out under warranty. My problem was mostly tied to audio cutting out, dying, then coming back randomly.

I had something similar. No radio, black screen.
It happened when i went to pick up the car at the window tinter. We he said it was nothing he did to the car since he was only replacing the rear hatch tint.
Jumped in the car when around the corner back to the dealer who had just done an oil change and he dropped it off at the tinter.
I got the usual "Gee I've Never Seen That Before" story. They took it in the back and did a reset on the computer and never had it happen again.
Go figure...FM

I have a 2017 Z51 2LT Stingray. My build was in October in 2016.
Mine was more of a freezing problem, though it caused audio to cut out and no matter what I did it wouldn't come back. Restarting the car didn't even help.
I have some footage of the issue up in a VLOG I made last year. Go to 3:30 in the video to see it. I can't get my link to go just to that for some reason.
My dealer had to eventually install a new HMI module. That fixed up the problem and it hasn't come back in over a year.

I think that I have had at least one minor glitch at startup with every GM infotainment stack starting with my 2008 CTS which would on rare occasion require a restart after a remote start for all of the separate audio amps to initialize and come online. My 2016 Z06 started one time with an apparently active radio except no audio. My 2018 GMC has required two restarts since I bought it in 2018 to correct an audio system that didn't initialize correctly and another time it required a restart so that its steering wheel audio and favorites buttons were operational. Once my 2014 ATS woke up and didn't see its USB ports.
All of these situations were resolved by a restart. Pretty much everything electronic in current vehicles is part of one or more vehicle networks and there is a lot of network traffic going on immediately after start and it seems that sometimes a conflict occurs that results in a temporary problem. This is the reason I wasn't terribly upset about having to turn my original version of the Range module on AFTER my 2016 Z06 was started in order to avoid a conflict that resulted in loss of communications between the ECM and TCM at startup; if GM has troubles getting everything to talk nicely during module initialization it isn't surprising that a third party producer would have some issues to resolve and of course the current version of the Range module works perfectly now without having to leave it off at startup.
These little glitches are one of the reasons I really don't have a lot of faith in autonomous vehicles in the near term because these systems are FAR simpler than what is necessary to make an autonomous system functional under real world driving conditions.
