Just a quick update on the return status in case if you have ever have to return your Tesla for whatever reason. According to Tesla rep, 6-8 week delay to get your money refunded. It's over 8-weeks now since I signed my return paper work, and I still haven't receive my refund from Tesla yet...

Yes for me, it was constant and therefore annoying from about 50-80mph.

my answers inline:

Interesting finding, Tesla told us it is related to front motor but did not tell us the exact mechanics of the noise. Can you actually it hear it?

Thank you all for great discussion! As some people here also confirmed that they have a similar issue, but my main purpose was to share my findings and make the potential buyer beware. It could be that my particular model had more than usual noise than other. Now it's up to Tesla if they want...

Thanks, one thing I noticed is that in your first graph, noise seem really high that it can bury any 4kHz tone. The 4kHz tone, in my case, is around -80dB. May be you can try turning off HVAC and use a quiet road? If you send me your recording, I can also check it on my end using adobe audition.

You can use any recording device. In my case I used iPhone voice memo with default settings.

long range

Thats interesting, do you have a dual motor system in your X? From Tesla feedback, it is related to high current drive in the front motor, but I can't speak on behalf of Tesla engineering, but that constant 4kHz doesn't really make sense to me. I have to physically start debugging to root cause...

Thanks for the confirmation! Good luck for a possible fix in a future. I believe there is a lot of mitigation techniques such as using some dampening material or noise cancellation circuitry etc that can be employed as a engineering solution, but in my case Tesla did not take any action to...

Yes, I am familiar with acceleration sound and have no issue with it but 4kHz tone is very specific and pretty constant from speed 50mph to 80mph and never goes away. The problem is that once you have tune into it and its just hard to ignore it.

I guess this particular noise will not be concern here, but will miss out on updated battery and higher mileage/charge.

Good point, but keep in mind other noise band is not in higher frequencies. If you listen to isolated pure 4kHz even with lower amplitude, you will get annoyed pretty quickly. Here is a link to pure 4kHz audio, feel free to adjust the volume down and try listening it all the way. This is what...

Hi Tom, Thanks for the feedback. Yes, recording was done at a constant speed of about 60mph. Below 50mph, its not as bad but still noticeable.

Hi Guys, Just want to share my recent experience with Tesla. I bought and returned 2019 Model X due to some high pitch sound in Cabin. I wrote my whole experience with some technical analysis here. For people who are thinking buying one, please definitely check out following post...
