My first post on the forum. I've had my new 2013 LC for a few weeks now and love everything about it but I'm pretty irritated with how loose the 2nd row seats are. I've tried to mitigate the problem by placing rubber tape around the D rings and placing large, thick sponges underneath the seats to limit motion. It has helped tremendously but not entirely solved the problem. The 3rd row seats are much more stable and do not rattle at all. I've noticed on other threads that this is not a new problem and I'm really surprised that Toyota hasn't yet solved this problem. Does anyone else have any ideas?
