Just wanted to add my experience to the list: I took delivery at the beginning of 2017 of a new inventory MS P100D so I'm assuming Q4 2016 build, and almost immediately noticed the rattle/clunking noise in the front suspension being discussed in this thread (#1 in the quoted wav file). I finally got it replaced at the beginning of this year after reading that this was a common issue with no known fix, hoping that by now it would have been fixed.
When I got the car back, the issue was gone and the car was sublime... for about a day. The day after, in the morning, I heard the rattle faintly again, and by the end of the day it was right back to pre-fix volume. So, no dice, there's still no fix.
I'm still trying to get the exact part number of what was installed, just to see - I didn't keep the receipt. I'll post the details as soon as I have them.
