Bought a maza cx-30 2020 gt sport mhev 2.0L. it's running really well but there is this very strange whistling sound coming from under the bonnet, both at idle and also when driving. I know some people have said the mazdas can make strange noises (high pressure direct fuel injection), but this sounds unhealthy to me and too high pitched. Wondering if could be an alternator belt issue?
Anyone also got this sound or any idea what it is?

Can't upload a video but you can see one I posted on Reddit

Welcome to the forum

Your video should at least be done with the hood open?
