I have never heard high-pitched whistle after the engine turned off on my 2016 CX-5 GT and my current loaner - a 2017 CX-5 Touring. May be my hearing needs to get checked? (dunno)When I turn off the car, there is a High pitched whistle coming from under the hood. Lasts about 30 seconds or so. Is this normal? Could it be the flux capacitor? (eyeballs)

We don't get i-ELOOP on CX-5 in the US, what is the flux capacitor about? (uhm)
Could be the AC unit pressure slowly equalizing. I shut my AC off about a block from home so I'd never hear it. I will check next time out. Ed
LED headlight fans cooling them down is my guess?
Do Mazda's have this (uhm)
I just checked my 2017 CX-5 loaner and you're right, The noise is more like humming noise from a transformer coming from the throttle body. It'll last about 30 ~ 40 seconds each time I shut off the engine. I've never noticed it because I always have my music on and can"t hear the hum from engine bay.They all do it. I think its the throttle body powering down.

Definitely not from AC unit and LED headlight cooling fans. No way it can be from flux capacitor as it doesn't exist!
That doesn't seem to sound right. I've just checked some Point of View CX-5 driving videos on YouTube and they don't seem to be making that noise.
Does it still make that noise when the engine is at normal temperatures (uhm)
