Hello from Europe. I have an October 2017 M S 100D. Just came back from SC today. After like replacing almost everything the last week they came with the same answer. Bad designed front suspension. Don't know about you guys, but it spoils the whole 'zen' experience of an electric car. As for me. I wait 2 months, but if there's no fix within 2 months I'll start legal action. A model S is a really expensive car - if I would have known that it would rattle like that I would not have made the purchase. So hope there is a fix soon ....
Let us know if you get anywhere, I completely agree that it spoons the zen experience. I do most of my driving in the city at low speeds over bumps so I hear it a lot.
