Radio not shutting off when I open my door

I have a 2002 Sunfire and until a few days ago, the radio always shut off when I opened my door. Now, it doesn't shut off immediately. It's almost like clockwork. After I open my door, it waits almost exactly 5 seconds before shutting off.

Not that it's a problem but I've had the car for 2 years now and until a couple of days ago, the radio always shut off as I opened the door and now it doesn't.

Anyone experienced this or know what the issue may be?

Did you noitice if the interior light comes on as soon as you open door? The switch in door is likely just gumming up

Mine is doing the same thing. Door switch works fine. It takes mine almost exactly 40 seconds for the radio to turn off with the door open. Also, with door closed and this issue happening, the alarm will not set either. But after 40 seconds, everything works just fine.
