2011 Sedan not fully shutting off

[ScottM]

Hello everyone,

I have a problem and have googled my fingers raw looking for a solution as well as calling 2 local dealers. They haven't heard of it.

What's happening is when I shut off the car, the audio video display stays on, and if I leave the vehicle with the key in my pocket, the car sounds the screaming noise it makes when you do that with the vehicle running.

To be clear the engine and dash does all shut down as normal.

Everything else seems to be working, I can start it, go for a drive, etc..
The check engine light is off.

Does anyone have any ideas about how to deal with this myself?

Thanks in advance for your help.....

Did you try the other keyfob?

Is there another fob left in the car? Also, have you tried disconnecting the car battery negative terminal in the trunk for about 5 minutes then reconnect?

I'm having the same issue in my 2011 3.8 Sedan. What was the solution?
