I had two rattles:

1) driver's side (left side in the US) rear seat latch - adjusted and fixed by the dealer
2) rattle in the back hatch - supposedly fixed by the dealer but there's still a rattle there.

I just went outside and checked on #2 since it was annoying me. If you actually hold the latch with your finger and try to move it around, it sounds exactly like the rattle I get. Once I figure out a way to stop it from jiggling, I will road test to verify that the noise is gone.
