High Pitch Whine after Shutdown

Hello all,
My wife has a 2013 3.6 Oscar Mike. Tonight when we came home, after getting out of the Jeep after turning the engine off, a high pitch whine came from the engine compartment. This was about 60 seconds after turning the engine off.

We have had the Jeep for about 6 months and she says it has started making this noise recently. Any ideas before we take it in? I just know it won't replicate if we take it in to the dealer.

Thanks

Right after you turned it off until 60 seconds? Or everything is quiet and then a minute later you hear the noise.

The noise is heard one minute after it has been shut off. The noise sounds air pressure releasing through a very small hole causing a high pitch whine/squeal. It only last for a few seconds...

I've heard what I think is the same sound. I usually hear it while sitting inside the cabin after it's been shut off. I think it is coming from the area of the temp control? Not sure it's the same sound. I assumed it to be normal, just wanted to know what it was.

I can hear something as well, very low, I have to pay attention, but it sounds like it's repositioning the flaps of the climate control.

Yeah my 11 does the same, I figured it was something with the cabin air filter system...

Perhaps it's just your supercharger spooling down...
