Humming / whirring sound (2019 CX-5)

[Jb0702]

Hello, I bought a 2019 2.0 petrol auto last July from local Mazda dealer. From day one I have noticed a whirring/ humming noise from the car. It is very noticeable during cold start and faints out after 20mins of driving ( but I can still hear that is it there). I wasn’t sure if this sounds I normal or not.

It changes its pitch as I change rpm and when I drive, I can’t hear it if the rpm goes over 1000. So usually very noticeable in P,R or even when I slow down in traffic. I took a video. Does anyone know why I am hearing this? Thanks!

Our 2018 CX5 (2.5 non-turbo US)) had a little of that sound when it was cold but it quickly went away when the engine warmed up.

Thank you, mine quiets down after the engine warms up but I can still hear it… maybe I am just being so dramatic!
