Why is my 2022 MG HS EV whistling?

The first thing to check here would be how well the door and window rubbers are sealing. If they’re not sealing absolutely 100 per cent, a whistling noise at higher speeds is often the result. This technology has come a long way but, ultimately, it all depends on the rubber sealing the glass and the door against the rest of the car. Inferior quality rubber has been noted in some cases, and other times a single bad batch of rubber has been to blame.

But the first thing to do is open each door and make sure there’s not a small twig or piece of tree stuck in the rubber as this can cause the same problem. At least the latter is easy to remedy.
