Car vibrating, rattling noise over 80mph

[YEmmaKazi]

Hi,
I picked up my Model Y Long Range with 20 inch wheels on 9/12 and totally in love with it . I do have a little misalignment but nothing major, overall quality is good. I took it to a track and it feels like the car will loose control at speeds over 90mph. My biggest issue is the vibration when I go over 80mph. There is also a rattling noise from the back when I pass 90mph. The car is very unsteady when driving over 90mph. In general the wind drag seems to be very poor and it's somewhat loud.

Did anyone experience this issue or have any recommendations? My service appointment is on 10/5 but not looking forward to the below average service experience based on other people's experiences.

Did you guys ever figure out the high speed driving unsteadiness? My model Y has a similar issue and it’s far worse than my old model 3. It seems like a widespread issue. I see a lot of people complaining, but no resolutions.

Hmm, based on the OP's description, one guess is the tires aren't balanced?
