Clunk from back seat area.
 

My in-law's Fit has a cluck that seems to be coming from the rear right side seat. I have found that it is either in a latch or hindge. They will be taking it to the dealer for a warrenty claim but I was wondering if any one else had this issue?

Maybe it's the tool bag clunking around in the spare tire area?

Could be your exhaust pipe is loose. Had similar problem in Prelude and eventually put a hole in the pipe. Might just need a hanger. ;)

The seat latch for the seat on the floor might be blocked by something so the seat is bouncing up and down on bumps, or the latch it's self is broken.

See the link I put up for this. It may be what I had.
