Model Y Buffeting

[ilovecoffee]

Do you have any more info on the tap on the hatch latch?

I did the rigid hatch stops with pvc, noticed an improvement and #2, #3, #5. Believe or or not the coilovers wasn't worth doing for the sound alone, ride quality better but boominess was still there.

Other than that link to the post from @after-dark who translated that video I posted, I don't have any more info.

I think they suggested in the video that wrapping the hatch catch with tape helped.

I put 1.5 layers of electrical tape on the latch and can't say Ive noticed a difference, but it's harmless to do so just leaving it on there.

+1 on Putting vinyl tubing in the gasket has definitely paid off; I think the booming is reduced by half.

Yep, just went to try the tape and didn't notice much. Between the gasket tubing and the pvc stops, the difference is good. I now only notice when going over bumpy roads at low speed is when the car transmits the low frequency rumble.

I'm a UK M3 owner thinking of buying a MY. A few weeks ago we test drove a MY, expecting it to be a no-brainer switch and just a bigger, more practical M3 (UK 2022 model, no rear parcel shelf). We were surprised by the air pressure feeling / buffeting feeling and both found it pretty unbearable on UK roads at medium speeds, that's when I found this thread.
We test drove a different, newer 2022 MY last week, which had a parcel shelf. I also did the 'envelope grip test' on the car and all 4 tailgate stops were nice and tight. That newer MY with parcel shelf had very little pressure/ buffeting. I wouldn't say 'none', but over the same roads it was much, much better than the previous test car. I don't know the manufacturing dates or locations of either car.
I now know I'm someone who does feel this pressure sensation, but I also know that not every MY has it bad. I just don't know if I want to take the gamble that any MY I ordered would be a 'good' one!

My car has the same buffeting issue, it’s a 2022 MYP. Service center said they couldn’t reproduce the issue. Adjusted the knobs doesn’t seem to help. I also have a Model 3 that’s just fine.

I am experiencing the air buffeting issue with my new MYLR. Burlingame Service Center stated that they couldn't duplicate the issue and nothing would be done.

Was your issue ever resolved?

Apologies in advance for a lengthy post, but a few things to report here.

I received the same message prior to my service appointment and thought it was generous that they offered a loaner (depending on availability) OR $100/day toward Uber/Lyft, so I kept the appointment. Happily, when I showed up, within about a half-hour they put their lead technician, who was very competent, diligent, and understanding, on it. We spent a good bit of time together in my car ensuring he was perceiving the same issue I was and talked a good bit about the nature of the suspension on the car and the general consensus in the forums that it is the rear door that causes the issue (I’m still not sure that is true—I think it may be the “frequency” of energy coming from the suspension on certain surfaces with a certain inherent resonance in the car frame, body, or interior, though rear door movement may exacerbate the issue).

After duplicating the issue by driving my car, we drove another MY of the same configuration (same wheels and suspension MY LR DM), and it had the same issue. Whether it was as severe as mine, hard to say. He showed me how they adjust the rear door and explained the function of the different adjustments. Contrary to what is popularly said in the forums, he said the four rear door “stops,” however tightly they are adjusted, provide minimal rigidity to the door compared to the actual latch, the body-attached rectangular “loop” of which can be moved to adjust the degree to which the door presses down on the seals when it is closed. He explained that to make it more fixed in place, the latch can be moved “down” so that the door closes more tightly against the door seal. Before we adjusted the “loop,” the door stops on mine were already adjusted out to the point that paper could not be pulled out from between any one of them and the door without tearing it. Adjusting the loop to “tighten” the door closure is a game of moving the loop “down” to the point where the door is pulled down further when the closing mechanism “cranks” the door down, but not to the point that the closing mechanism (motor) is not powerful enough to close the door completely. So, I was surprised that he was able to move the loop down significantly without readjusting the stops and the door was still able to close. Thus, the rear door on my MY now closes MUCH more tightly than it did before I took it for service, visibly more tightly, because there is now noticeable misalignment between the door and the body around it, though it is not unsightly because it is symmetrical left and right.

Key question, though: did it help with the irritating low frequency sound? No. Not significantly anyway. Certainly not on roads where it was a noticeable issue before. So I’m not convinced it is the rear door that is the issue.

Next step may be to adjust the door so that it closes less tightly than before to see if that helps. I am curious whether the issue is as noticeable in a performance MY which has a different suspension. I’m also curious whether a different suspension such as an air suspension would help. In any case, I’m surprised Tesla makes a car in which such an issue exists, though obviously the MY is not the only car with the issue — MS suffers from it, too. I’m pretty busy so I can’t dedicate a huge amount of time to going for service over and over to try to resolve it, though I wonder if it could be escalated so that Tesla engineers would have a look at it. I’ll keep you all posted.

I can tell that my MYLR hatch lid is not symmetrical left and right. That might be one of the reasons for the air buffeting. Can someone share some hint how to DIY adjust the rectangular "loop"?

Thanks!

We have this booming issue on our new Y. I reported it as a service issue. They listened to it and told me it was normal. Today (4/11/2023) when I went in for a different issue, the tech remembered me and told me they now have a fix for the booming and he added it to today's ticket. He indicated it did require part(s). I have not yet picked up the car but I am hopeful!

I wonder if it is just adding the package shelf that the new MY's have now. Let us know what they do.

It'll probably be these rubber dampers

Can you share some pics of where you put it on the front wheel wells? Looking in the frunk, I couldn't find a place where they were exposed enough like they are in the rear. I haven't pulled the frunk out yet. When I first got my car I pulled the covers off of the exterior of the wheel wells...

Any update on what they did? And would you mind posting a snippet from the service invoice?
