New Model Y high pitch whining sound

I got my Telsa Model Y on later Oct. It is pretty new and I found there is consistent high pitch whining sound while driving (seems > 20 mph) and sometimes goes away a short period, then come back. Attached is a mp3 file I recorded while driving locally about 30 to 40 mph. This annoying whining sound also repro while driving in highway (though I didn't record it).
By the way, it is interesting, and very odd, that the sound seems not repo driving in rain ... I don't know what does this mean, and cannot 100% sure if this is just a coincident, but most time I drove, the sound is in my ear and in my brain, it made me crazy. I love Tesla, almost everything but this annoy whining sound.
Can anyone please listen the attached file (especially 2bd half from 30 seconds) and see if you have similar issue, and how did you solve it?
I had appointment for a service in early November, but the service center told me the issue cannot be repro. I now schedule a new service (two weeks later) with a recorded sound. Hope I can get some help from this community before service center. This sound really kills me.
P.S. I have problem to attach a .mp3 file in this post. I renamed the file to .mp3.txt. If you can click and open it directly, please download and rename the *.mp3.txt back to *.mp3 and list.

I would think it’s likely the rear motor ground strap/cable.
This is a common fix for the infamous whine, if your car has it.
They all whine a bit when cold, or when pre-conditioning.
Constant or loud, even in warm weather usually points to the ground cable.
It’s usually loose, but they usually just replace it.

Can you say more or point to more info? It really sounds like jet engine when accelerating or driving along. It was disappointing to hear because I expected to hear only road noise when I received my Y in Nov 2021.

It was determined that the ground cable to the rear motor is often the culprit.
I’ve had the whine for years. Thought it was normal. Had the cable replaced about a month or two ago. All different now. Only hear it when cold or preconditioning to a supercharger. Even then, it’s quieter.
There’s a service bulletin out on this from Tesla as well. Not sure where to find those now though.
