I've bought two Model S's in the last 6 months. On the first car, I noticed that the driver's door metal trim that runs horizontally had a series of about four little dents/dings. I brought this the Portland Service's attention and they replaced the whole door panel. Yesterday on my month old car, I noticed the same problem - a new dent/ding. I emailed service about this and they replied that this doesn't fall under warranty and that the last repair was a courtesy. It seems to me given that this has happened on our two brand new S's that there is a problem with the metal trim. It should not dent so easily. We are not heavy users of our cars and don't treat them roughly by any means. Has anyone else had this issue?
