My 2023 Model Y Long Range (6/2023 delivery) makes a similar high pitched noise around 50 MPH.
The noise is within the range of 8k-10k Hz with 30dB gain. See the attached snapshot of a recording on GarageBand.
It usually starts around 50 MPH, but is otherwise present in a much wider range.
After it starts, even if speeds go below 50 MPH, the noise still tends to stay until the speed is below 30 MPH.
Noise is intermittent and comes and goes with seemingly no input from the driver.
Here is a video demonstrating the noise on audio analyzer:
Tesla Noise
The noise starts around the 8th second. Notice the spike in intensities around the 8k-10k Hz range when the noise starts.
Tesla says this is a normal operating sound, even though it is not one of the noises they have under their
Normal Operating Sounds list.
1st SC visit - tech said they can't hear it.
2nd SC visit - they can hear it, it is a "gear lash", normal noise, most Teslas make it, some are worse than others. Come back later so that eng team can have a look as well.
3rd SC visit - they can hear it, it is a "bearing in FDU", normal noise, no risk to reliability or safety. Though as a goodwill they offer replacing the FDU with a remanufactured unit as a one time thing only. Even if the noise gets worse, no further replacements will be done. They did mention past replacements had a low success rate.
I took the case to NCDS arbitration requesting replacement or repurchase on the grounds that the noise isn't one of their Normal Operating Sounds and that Tesla refuses to take responsibility to fix it if the replacement doesn't work or makes it worse.
NCDS denied the claim. Rationale - "a subjective impairment that one driver may find unacceptable, but another driver may find normal."
Those that proceeded with FDU replacement - did they replace with a new or remanufactured FDU?

Has anyone succeeded enforcing state's "lemon low"?
