My last ride with the tech at my local SC backs that up. He told me he's had multiple people coming in for other issues where he's also noticed the loud FDU noise and was surprised the owner wasn't complaining about it.

Just had a visit to the SC yesterday for our Model Y continuing to make this noise after a FDU replacement last spring. What I heard from the team definitely validated what those in this forum have been saying. When my Model 3's FDU was replaced in late 2022 the narrative was "we are starting...

Agreed. My wife and I have been unfortunate enough to need FDU replacements on both our 3 and Y for this issue. Tesla 100% would not replace a drive unit for something that was normal for the vehicle...

My understanding is that they will replace it with a remanufactured unit, but not 100% sure that’s true in all cases.

Also curious if anyone has an update from their SC on the path to a long-term fix. At the tail end of last winter I had finally convinced Tesla to replace the FDU in my family's Model Y (after already having had a FDU replacement resolve the issue in my Model 3) and by the time we got the car...

Update for the group on our Model Y - TL;DR is they've replaced the front drive unit and the noise is gone, just as it was with my model 3. We had brought the Y to the Service Center on April 11th and they had determined it was the rear drive unit making the noise. This had seemed odd to me as...

I was questioning that myself, but the tech said they've done a number of these since the SC worked on my Model 3 with this same issue, so I have confidence that they know what noise they're looking for. Said that it was a loud electrical pulsing noise coming from the rear drive unit. The real...

Good point - The replacement did fully resolve the issue on my Model 3. My wife's Model Y has now been officially diagnosed and the parts ordered, but they can't get me in to perform the work until May 1st. I'll report back when we get the car back to let everyone know if that did the trick...

I had first gone to the on in EP off Wallace Road and did not have luck in resolving the issue. I then went to the Washington Ave EP SC and they've been very helpful.

I had previously posted on this thread about experiencing this issue with my Model 3. Tesla ultimately ended up replacing the front drive unit under warranty. My wife then purchased a Model Y and was experiencing the same issue. We finally got around to bringing it in and had some interesting...

This is what was on the invoice to resolve the issue. So strange that this wouldn't resolve the issue in all cases. The tech said that they got the car up on a lift and ran it up to the speed range where I was hearing the noise and the drive unit specifically had been making the pulsing sound.

Got my M3 back on Friday and am happy to report that the noise seems to be fully resolved. No longer hearing the chirping sound at any speed. Unfortunately in the process they messed up my alignment so I now have to hold the wheel ~5 degrees to the left in order for the car to track straight so...

Bummer to hear that it's taking that many service visits. Good idea on leaving the car to cold soak; I think that's why it wasn't replicable for me when I went in last week. Got an update that the front drive unit needs to be shipped in to the SC so they won't be able to do the repair until...

Sorry for spamming the updates here; just received confirmation that the drive unit is being replaced!

After waiting an hour for the issue to be diagnosed they're saying that 3x techs all observed the problem and they've validated the issue is coming from the front of the car as expected. The words "drive unit replacement" were used as they walked me through next steps, but said they wanted to...

At the SC now. Good news is that this tech said he can hear the noise and says that while it’s a similar pitch to wind noise, the pulsing makes that seem unlikely. They’re taking the car out with 2x techs now to try to better diagnose. Fingers crossed…

So glad I found this community. I have been experiencing this issue on my Model 3 (I know this thread is under the Model Y community, but couldn’t find much documenting this exact issue on the model 3). My car is a September 2022 build Model 3 Long Range which I picked up in late September...
