MXLR Refresh High Pitch Sound Accelerating

[Maybe22]

Title says it all — anyone else experiencing this? More noticeable at highway speeds, ie, 50 -80 mph. Sort of like very high pitch dental drill… appreciate any feedback ty

I do.. its a high pitch whining sound. Much more pronounced then when I drive my Model Y... I have it on my list for the service shop next week

I notice I can sorta 'modulate the sound' by slightly letting off the pedal and then pressing it back down a bit

Yaa me too — when was your car built and is it LR or Plaid? Do you think it’s “normal”? I wonder if the whole front drive unit might need to be replaced? Seems like it good be a big deal??

Mine was built 2/12 — LR

My 2018 X had a slight high-pitched noise in those speed ranges. Took it in and they said it was normal front-drive noise.

From Raven onwards I'm pretty sure they introduced the new front motor from model 3 design. I have this same issue on my 2019 Raven S. The whining is indeed by design and you get used to it. Annoying, though.

Isn't that a permanent magnetic design? Does that mean the newer X/Ss can be driven with one pedal and will come to a full stop without pressing on the brake pedal like a 3?

 

[Kilowatt]

Yes, that’s right!

Here is a link to a video of what my MX sounds like… I’m assuming everyone else’s refresh S and X sounds the same…

Mine (refresh MX just delivered) has the high pitch sound too when I accelerate it. It's probably normal.

Sounds similar to the model Y, which is normal.

Yes, and the high pitch is normal for this type of motor.

Just dropped off for service today and had that on my list. It seems to only do it intensely/loudly when I floor it from a slower speed. I do hear it faintly but continuously at high speeds though.
