Pretty sure mine has the same problem. It's a March build. The noise is noticeable after it's been sitting for a short while after being driven and restarted. It isn't as audible outside the car, but you can hear it under the passenger dash inside the car. My 2022 didn't make this noise.

It goes away after the car has been driven. I'm taking the car to the dealer tomorrow morning with a printout of the TSB.
