This thread is pretty lengthy and it seems there are a few different issues being discussed. I've noticed within the past month or so a "rattling" that seems towards the front of my Model S (2018 P100D) under hard acceleration (75%-100% accelerator press). It seems to have coincided somewhat with colder weather. It is less noticeable with "low" rather than "standard" suspension, but still present. I have no rattling under normal acceleration or speeds. It does not feel unsafe -- it's more of a slight vibration and an audible sound than anything. Has this problem been solved/addressed/experienced?
