Air release noise from engine? stock 2011 v6

If anyone else has a 2011 v6 auto that can test to see if it happens on theirs to that would help. It only happens when you turn the engine off. See video

I have a 2011 v6 automatic. The Styrofoam crap is just to deaden sound and not a heat shield, I think ? That's what I 'think' its for. My Mustang 'does not' make this sound. Come back when you find out what's doing it when you find out

I have determined it is coming from the intake. I took the cover over and stuck my head in there and put my ear to the hole leading to the throttle body and it made the noise much louder. You can even kinda feel the rush of air coming back down the intake from the throttle body. I will be taking it to the dealership to get it diagnosed. I am afraid the rodents probably chewed up a vacuum tube/seal somewhere and that is why it is now making this noise...

these cars want to be driven so sometimes when they're turned off they just sigh

Are you 100% sure it does not? I have determined it is releasing air back down the intake tube.

OK. Good news for you. I just went out and checked. Mine does it too. I've never noticed it before, probably because I always have the radio on plus my mufflers are a little loud

I have come to the conclusion this is "normal" and I just never noticed it before. I have not had the car very long.
