Does anyone's seat have a slight rocking motion to it like its not bolted in properly? I'm on my second Model S, the first a P85+ and I had this same issue on my first car (Classic Seats) and now my P85D with the Next Gen seats still have that 1/2" rock that I notice when the car is under braking conditions. I've noticed this in a few cars I've sat in and some demo cars I've driven. Does anyone else have this issue and was your service center able to address it? Thanks in advance!
