Whistle noise, only one every morning
 

So you know how the car revs higher at cold start with the blue light on, well being that my car is garage kept and I live in Florida, so I don't let the car heat up very long.

so once I pull out of my driveway and drive to the stop sign maybe 20mph max, I hear a whistle like the car is sucking in a lot of air, it just started maybe 2 days ago. but once I stop and drive again it doesn't do it.

I was just wondering is anyone else has had this?

its a new 2013 mzada3 with Skyactiv, automatic, 1,400 miles.

Any input is helpful, thanks
