2017 CX-5 High pitch noise when accelerating

[virusdmk]

I recently bought Mazda CX-5 2017. The car has high pitch noise when accelerating. I tried to push the throttle pedal when doesn't move - doesn't have noise. Just when it moving. It's seems for me it's like noise goes from dashboard(driver side), when I get closer to dashboard, looks like noise from there. But I'm not sure.
I don't think it's noise from wheel bearing. I heard it before, it's different.

I read forum similar threads but didn't find solution.

Guys, help please

Does this happen when the heating or a/c is on AND off? I had a similar issue and it ended up being a small piece of leaf in the cabin intake blower under the dash. It’s fairly simple to remove the blower motor and clean the filter out - if that sounds like it could be it?

If that’s not the case, no idea what it is.

Do you think it could be transmission?

Does the noise change when you brake? Make sure there is not a small rock or gravel between brake rotor and pad.

That is not the normal hypoid gear whine of the Skyactiv transmissions. That’s exactly my concern. Dealer is giving me a hard time about it and says it’s good now. It’s not. Going to take it back.
