Why I returned my 2019 Tesla Model X?
- Thread starter Kashif
- Start date
Below are measurements i made on my Raven model S at 55 mph and 35 mph using a Zoom H2 recorder and Audacity FFT analysis.
Peaks (tones) are observed near 4 KHz at both speeds and more peaks at 11 and 13 KHz at the higher speed.
It appears that the high pitched noise is simlar to that reported in this thread.
My guess it ithat the noise is related to the new front motor.
I would like to have this fixed, since I did not hear these whistles on my pre-Raven S.

The noise will have a linear relationship with speed. It's permanent magnet cogging, as above. The motor is just not as smooth as the old induction motor.
I'll be amazed if Tesla does anything. They already either did the best they could, or found the noise to be acceptable.

Hi, sorry about you issue.
I'm a little puzzle now about getting a Model X. Test drive are a little bit short for making a decision.
I was considering to rent one over the weekend to get a better feeling but finding a Raven is not easy.
I know you can return it but this seems to be a lot of trouble too.
- I was wondering if you were able to get your payment back, or how long it took or will take to get it back?
- Just by curiosity, what equivalent car you bought, or plan to buy istead, or hesitate or been hesitating between?
- Would you recommend trying finding a pre-Raven instead?
Either it's gotten a little better with time, or I'm just better at ignoring it. It's definitely not 100% gone though. That said, I LOVE the new suspension, I can never go back to a pre-Raven.
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?
I am considering trading in a 2018 Model S for a Raven S. Very interesting info here. On the short test drive I had, I did not hear any high-pitched whine, but I did not know about this issue at that time.
I listened to the audio sample the OP provided. I can hear the 4 KHz whine in the beginning of the clip, but it got much fainter after about the 7 second mark. In real life, was the whine amplitude constant (at a constant vehicle speed)? Anyone knows whether the problem is more severe in the Model S?
Is there a way to rent a Raven S for a day? Or maybe get a longer test drive to take it to the freeway?

Doesn't any of the Bay Area showrooms have an S Raven you can test drive?
I just test-drove the raven S a couple of hours ago. I can hear the high pitch whine, but it's at a very low level. I don't think I would be bothered by it.

Great. I hear a bit of whine in mine, but only at certain speeds say 25-40 mph. It is like a much quieter version of a BART when they first start off from a station. When I drove forklifts they made a similar noise when acclerating. So to me it is just electrical motor whine like ICE engines have exhaust noise.
The senior Tesla tech in my area agreed he could hear the whistles and took a recording using a Tascam portable recorder. He escalated the sound clip to the Tesla NVH (noise, vibration, harshness) engineers who have reported back stating the noise heard is well within the expected range. I interpret this to mean that there is no solution offered by Tesla.
I have driven 3 examples of 2018 models without any whistles and 3 examples of Raven, all with whistles.
Some people like the OP and me are very annoyed by the whistles, others not so much or not at all.
If you are one of those who is annoyed, what to do?

On the Model 3 LR AWD, you can slightly hear when the front motor get engaged, like when doing sudden accelerations,
but I never noticed a whining noise, I think the road noise would be more noticable.
I started to become a little bit picky on this subject, by preferring riding on a less noisy road, when I have the choice,
even if I have to make a little detour.
Just picked up a Raven Model S. I hear the whine but only at highway speeds and only when motor is at certain RPMs. Specifically when it is consuming <15 KW or generating <15KW or so. Outside of that range the noise is non-existent for me. The issue isn't nearly bad enough for me to return the car, and many times road/traffic noise or the sound system drowns it out completely.
The 3 has a permanent magnet motor in the rear and an induction motor in the front. Therefore, the rear motor in the 3 is the appropriate one to compare to the front motor in the S/X Raven refresh. OP, the ~4kHz tone in your audio sounds identical to the tone I hear in my RWD 3 under hard acceleration at any speed.
