Based on my research into this, I agree with this post.I asked Tesla about the suspension when I was last at the service center. They said there have been no suspension component revisions since the Y was released. (I have an early 2020 build.) This squares with the parts catalog which shows a single set of springs and dampers regardless of VIN. So I think the anecdotes of newer Y's feeling softer can't be related to the suspension. Maybe there's something else going on, or maybe it's just rationalization bias for upgrading to a newer Y .
