I bought a 2019 Eclipse Cross 6 months ago and it’s been good. But recently whenever I accelerate I would hear a electronic whirring coming from the middle of my car just underneath the middle AC. I checked all my fluids and there all good. I’m not sure if it’s a problem or if anyone has encountered them. I put my car on neutral and revved it and didn’t hear it and only happens when I move the car.

I reckon it's emanating from your CVT transmission, which are known for their whirring/droning noises. The fact that is doesn't happen when in neutral sort of confirms my belief. It may be that you just didn't hear it before because it was a new car to you, and now that you've settled into it you are more aware of all its little foibles.
