Triple Honk when powering down car...

Earlier today I ran through the drive-thru at Dunkin and then parked for a moment to get situated before taking off again. My fresh coffee was cold, so I shut down the car to go inside and get it replaced.

The instant I turned off the car, it startled me a bit with the dreaded "triple honk"...

There were no messages on the DIC or anything. I was able to lock and then unlock the doors with the button on the handle, and it started back up fine, without any messages about the remote or anything. Random anomaly, or was it trying to subtly tell me something? :confused:

Edit: I should note that all the doors were closed when I shut it off, as usual.

I have a 2017 LT. The first time I turn the car off after charging I get the triple honk. This happens every time except if I open the door before turning off the vehicle (I imagine the door chirp overrides the honk). I charge outdoor with a level 1 charger. The charger is in the trunk with the cable and an extension cable coming out of the trunk (for security). The trunk is not completely latched all the way but is latched enough to be locked. The trunk light goes off after 10min. Can the car be "remembering" the trunk is open and honking about that?
