Does your daughter show any evidence of a burn on her skin from the shocks? If not, could she have a problem with a nerve in her arm? That could, when the arm is twisted just so in closing the passenger door, possibly create a neurological symptom that might persist a bit.

I don't think your dealer will do anything. You should either trade the car in to them, or put a ground strap on it, static-guard the seats, and see if the problem is solved.

Did these shocks occur in a dry climate?
