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.

My 2020 Blazer just started doing the same thing this week. I'm assuming its a software/update issue vs hardware since we both have the same symptoms during the same period of time. I confirm that the radio do shut off just not when you open door like in the past.

This is good to know, my 2019 just started doing this with the radio this past week. My auto start/stop hasn't been working since December. I have an appointment at the dealer on Monday. Hoping it is just a software update they can fix quickly. I hadn't noticed the dome light but will pay attention to that this weekend before I take it in. Thanks All
