My LR has the vibration issue. Feb 12 2022 delivery date. I played around w/ various settings, it seems my car is at its smoothest when I set the suspension to low, advanced suspension -> ride comfort to soft, and handling to comfort.
Not sure if it's related, but when I do floor it occasionally, sometimes I get noticeable vibration in the yoke even at higher speeds. I've driven a few loaners (P90Ds) and it's buttery smooth acceleration all the way. My theory is the vibration at ~43 gets amplified when you don't let go the pedal and the vibration doesn't get a chance to die off.
To be perfectly honest, the occasional hard acceleration vibration bothers me more, even though I don't do it very often. In any case, from following this thread and a couple of other threads that the vibration does go away w/ further lowering (w/ lowering links) and/or track mode that favors rear motor? It makes me hopeful that it could be solved by software one day - I would gladly trade off a few tenth of seconds 0-60 for buttery smooth acceleration at all speeds.
