Evaluate more options. Could this little plastic bit not be the problem and the actual problem be the real cause for the recall? They have to track back the origin of the plastic piece.

  -maybe the tiny piece is not the problem?
  -maybe the tiny piece is not the problem but consumer 
   perspective and therefore cheaper to recall than 
   image damage?
  -maybe the piece belongs to something wearing out
   and the possibility of something (a chemical for example)
   being introduce is a possibility (and therefore a
   legal demand?)?
  -maybe there is no problem, but is better to recall than
   to have x reports on a non existing problem.
