One of my kids was being a kid and either broke something or was just there when it happened (you can pick your version).... End result is a small square (ish) black piece about half the size of a stamp fell out of the charge port. Upon further inspection, it had a matching "from" shape in the inside corner of the port door and looks like it was originally bonded (glued) in place, but for whatever reason was no longer. Being the engineer that I am, I cleaned up the surfaces with some isopropyl alcohol and re-bonded the piece back into the door. As I walked away with the spring clip in place to assure a nice cure, I was struck by the fact that I've got a spring clamp attached to the charge port door glueing a little piece to my $60K car! Anyway, it seemed too easy vs messing with a service call. I'm guessing it was a magnet/plate for sensing door position? Not sure because the door seemed to function fine without it. Anyone else seen this "piece"?
