Similar issue with my CT, had faint etched writing on the hood - "?? of coil #9". It was much more noticeable in certain lighting and angles, so I did not notice for several weeks after taking delivery. BKF actually made it more noticeable. Submitted a service request and Tesla had me take the...
Thanks for sharing, that really sucks but a good datapoint. Both you and @Darryl2006 had the FDU replaced without success. Worked for @Hammy60 and I.
If putting the truck in neutral when the sound is occurring causes the sound to cease it points to an issue with the FDU. Since @Hammy60...
Same. Replacing the FDU fixed it for me. There is a duplicate thread with recent updates here as well.

Thats very helpful you were able to make the noise disappear feathering the accelerator. You found the sweet spot where no torque from either the motor or regen was imparting torque / load to the drivetrain. This is essentially the same as neutral test I mentioned above, which points to torque...
ChatGPT suggested a test. Get the Cybertruck up to around 45 mph where you can hear the noise and shift into neutral. This can help differentiate between aero causes and drive unit torque related causes. I tried it on mine just to make sure it’s safe, and it was, there’s a “Hold for Neutral”...
Yes, its gone in the cold weather. However, I never noticed a strong correlation between temperature and noise. It started in Atlanta in September when its still hot and the noise was persistent.
Only thing related I can think of, is when I took it in on Nov 20. The high was around 75. I...
Long time lurker. I had the same issue - static like / mild grinding noise between 40 - 50, disappears when going around a curve. Have an AWD VIN 53xxx, purchased as inventory in June and the noise started around September.
Took it in and they first replaced a window seal and bearings. Picked...
