Hello did you ever find the cause. I have an 2020 GMC Sierra 1500 X31 and it started this morning when I pulled up to go into the store and my radio refused to turn off. Cranked the vehicle twice and turn it off to no avail. so I left the vehicle locked and went it and still the same problem. Suddenly an update message popped up so I am letting it update itself and hopefully this will help.
Radio (infotainment) stays on after exiting vehicle **now window motor issue per dealer**
Today my infotainment system stopped turning off when I turn off the vehicle and exit.
Have tried a few things including:
removed USB drive with music
disconnected cell phone
removed vehicle profile
tried opening & closing all doors several times (see below)*
called onstar for remote diag. (nothing helpful)
disconnected battery for an hour
*As a side note, the dome light does not come on with the driver door during this problem but does come on with the other three doors & hatch. And when the radio does eventually time out (10 minutes I think), the drive door does activate the dome light. So it does not appear to be the physical door sensor.
None of this helped, so off to the dealer I go with my two month old Blazer with 1200 miles. :-(
If anyone has any ideas, feel free to post.

For everyone that has this problem I went into my updates and let it update itself and now things are working properly. So maybe you maybe try the same.Hello did you ever find the cause.

Am glad you got it taken care of.Yes, some have said that doing an update fixes the issue. My dealership replaced my driver window motor and said it was the problem. The explanation was that the door switch communicates with the small board in the window motor and that in turn sends a signal on the CAN bus (link to computer). So mine went bad per the tech.
