Model 3 Rattle/Squeak

I have a new Model 3 and it has started making this intermittent sound from the back seat, it sounds like a sort of high pitch tap/rattle (

One thing I have figured out is that the noise stops if I unlatch and relatch the rear passenger side back set, it then seems to come back a few days later. I've tried adding felt tape to the metal section the latch hooks onto but that doesn't seem to have stopped it, has anyone else heard a similar sound to this or have any ideas?

I’m just over a week with my M3 and I’ve got a rattle in the back as well. I should try to see if it’s the seat latch but it sounds a lot like the back deck rattle I had in my Acura. I’ll post here once I diagnose. Frustrating to have to root a rattle out right away but the car is still amazing.
My car has this exact sound. I've noticed I can make the same sound by pulling up and down on the seat back when it is in the down position, so I don't think it is in the latch. It seems to be in the pivot point between the bench and backrest. Does anyone know how to remove the rear seat back cover? I can't see how to get to the pivoting mechanism without removal of the cover.

This is correct, There is a small metal cylinder that connects the smaller back seat to the larger back seat, it goes through this metal loop/hook that is welded to the body. There is some kind of plastic washer in there. When you go over bumps the larger seat shifts left to right causing the plastic on metal squeak.
