Beeping coming from rear after stopping ecodiesel

[00 Trans Ram]

Had my 2020 JLU for a few weeks now. Every time I turn the engine off, there is this beeping that comes from under the rear of the vehicle. It lasts a few seconds (10-15) and then stops. It doesn't sound like a fuel pump (my wife's Land Rover Disco Sport fuel pump continues pumping, supposedly for cooling purposes) or anything else. It REALLY sounds like an electronic beep, not mechanical.


Any ideas what this is?

Can you record it for us so we can hear it?

Maybe a dealer installed anti theft alarm that wasn’t uninstalled as part of the PDI service?
