I have the same problem. Im about to put something on the door seal to make it stop. Could be out of whack cause passengers seem to slam the door.

 

I added more of the round rubber stoppers on the door jam to increase the pressure on the door once it was latched with very little difference if any.
All the body lines are nice and even and nevr had a need to slam it to get it to latch, thought the added rubber stoppers would mean additional force woul be nded to close and latch it properly buut no change or improvement. I guess I'll move the postion of the door latch to increase the pressure to get the thing to quiet down. Driving me crazy!

 

Did you flip your striker already? If not try it.

Also grab a screw driver and with the door open - close the door on the screwdriver and pay attention to the latch mechanism. It is a metal latch with a plastic black covering. When - not if - that deteriorates and/or falls off then you get slop in the door with everything else being as it should.

 

I had rattling on both doors (more on the driver's side), and I couldn't find anything wrong with my latches or catches or paneling. Tried some different things, but after wrapping electrical tape a few times around the catch (where the latch locks on), that seemed to take care of it.
