I purchased a Kona a month ago and there's this high-pitched whistle I keep hearing when I drive with the windows down.

It happens mostly when I'm on the accelerator. It seems to quieten down a bit if i fullly turn off regenerative braking but I think it's still there.

You can only really hear it when there's a wall or something nearby bouncing the sound back. On an open road I can't hear it at all, and with the windows up it's gone completely.

Is this a Kona thing, do all EVs do it, or should I be getting mine looked at?
