Putting the kids car seat back in the left rear seat I noticed the latch bar on the back of the seat is loose. Moves side to side and back and forth. If you pull on the bar you can see the whole back of the seat flex. Something appears loose or broken. How do you get the carpet piece off the back of the seat to inspect the stuff?? I pried on it a little but it seemed solid and I didn't want to break it. Just doing that seems to have loosened the carpet piece a bit. I know I should just take it to the dealer, but if it's easy enough to just tighten a bolt I'd like to take care of it.
