I’ve seen posts about this issue on the MY and M3 forums, but not for the refreshed model S. I get a high pitched whine (sounds like a dental instrument) during acceleration that is most noticeable around 30-70mph. It comes and goes and oscillates at times too. In the MY forum they mention a missing penthouse perimeter seal that fixed the issue on some cars. I have a service scheduled, but wanted to see if anyone else has had this issue and resolution for their refreshed Model S. Thanks.
