I have the leather interior option on my '03 Sport model and the other day noticed that the passenger seat has two 'bumps' that protrude up from something below the leather skin. It's hard to describe, but if I press on them with my finger I can feel something hard inside there. It's really high up on the seat back, below the headrest, and out to each edge of the seat back on the front-facing surface. Does anybody else have this? What is underneath that's protruding?? I just don't want it to cause any damage and eventually poke through the leather.
