    I wonder if it’s missing sound dampening material for the motor.

    This frequency range is very treatable, but you need to get the right material into the right places. My other EV simply has a little jacket over the motor, about 1/2 inch thick.

    Could they check that the sound treatment is installed?

    Great supporting evidence! Mine only makes that high pitched whine if I accelerate really hard, but then there's nothing to hear after I'm done accelerating hard (I don't mind this at all, but M3 SR+ didn't do this at all). Yours is constantly there, which would drive me nuts as well, and Tesla should fix this, IMHO.

    Exactly what my 89K VIN does, but I thought it was coming from the rear motor. Will need pay closer attention next time.

    Decided to get a proper video of a drive. Phone is on a tripod in the middle rear seat.

    Sounds like a jet engine taking off, IMO that ain't normal. My MY doesn't do that unless I'm flooring it, and then I expect it. But your car seems to make a whole bunch of other noises also! Whew.

    Yeah, I'm super disappointed with the vehicle right now and the SC for being so dismissive. I'm planning to remove the rear seat cushions myself and try to see if I can find anything abnormal.

    Even without an A/B comparison that sounds abnormal for any EV. I drove a Model Y the other day and it did not sound like that.
    Really sounds like someone forgot to add the acoustic barrier for the motor.

    I pulled out the lower rear seat cushion and it does not appear that the Perimeter Penthouse Seal is present. I believe there should be a gray sponge material in the lower part of the cavity here.

    My 89k vin makes this noise when any regen bars are present. As soon as the regen bars are gone it’s completely silent.

    Saga Update:
    I took my car to a second SC on Feb. 16 and explained the issue. A tech. drove the car and agreed the noise was unbearable. They said they would do some troubleshooting to determine what the cause was. I also asked if they could verify the penthouse perimeter seal was present and they agreed they would. I showed them a video of the noise and (what I believed was) the missing penthouse perimeter seal and they told me to send the files to them so they could add them to my service file. (I sent them a link to dropbox)They got back to me later that day and told me the rear-drive unit needed to be replaced but they would need to order the part and scheduled a new appointment for March 1st.

    I took my car back on March 1st and they replaced the rear-drive unit. I got a call and was told the noise was still present and they would need to do some more investigation and asked to keep the car another day; I agreed. They called back at the end of the day on March 2nd. They figured out what was causing the issue. It turned out to be a...missing penthouse perimeter seal. o_O

    Picked up my car today and the issue has been resolved!

    TL;DR: Issue Resolved; missing penthouse perimeter seal.

    ^^^: Sorry you had to go to a different SC for a resolution to your issues, but very pleased they were willing to pursue it, and solve it. Thanks for being persistent and not letting Tesla off the hook for this!

    Amazing! Really glad you got it fixed. You could have just ended up as another "Within spec" casualty otherwise.

    Glad your issue has been resolved even if it took a second service center to correct the problem.
