2016 Sorento SXL
Those buttons are soft buttons. (logic signals normally and not power interrupting type of the old days). Hence a signal is still missing to tell it to power down when the door opened and the engine is off. Thats the way I see it.I hadn’t mentioned that we can turn the radio off with the control button.
Thanks. Dealership it is.Cant exactly say for a 2017 but in my 2015 SX it's controlled by the 'Leak Current Autocut Device' within the BCM. The audio and a few other devices (power windows, door locks, interior console lights) stay on till door is opened, OR for a fixed amount of time (5-10 mins ??) after the key is turned off. Dealer is the best option as they have correct schematics for your exact model, and can see if other devices on the circuit beyond the audio are working or not.
my 2016 cadenza does the same sometimes i wish it would last longer eventually it goes off & that is with me inside but the car shut down. I am not sure about the door as i have never tested it but will next time. Nothing like wanting to finish my favorite song playing.On my 2016 ex the radio will shut off a few minutes after I turn off ignition . Even if I stay in without opening door. Take it to dealer if still under warranty.
Where is the head unit and resetting does what. I carry a small ratchet and socket to reset my puter bc my lift gate on my 2018 Sorento sxl keeps acting up.If the BCM thinks a door is still open, then you won't be able to lock the car, and you'll see the door ajar icon on the dash. Given that neither of these is happening, I really doubt it's in any way related to door detection.
The battery disconnect is a bit radical, but will probably work. There is a tiny hole in the face of the head unit designed for a gentle paper-clip reboot.
So it was the switch after all. Where was it hidden?We had the door switched replaced at the dealership. $240.
We could haves continued shutting off the radio and headlights, but would rather have it work the way it was designed to.
Thanks for all of your suggestions.
