Don't think getting upset at FCA not covering something that far out of warranty is reasonable, but also agree the door should last longer. But things break. Perhaps you could reach a compromise with your dealership and see if they will sell the parts at dealer cost. I would try talking with your sales person if they are still there, parts office really has no reason to sell parts cheap, but sales person may want to try to keep a possible future customer happy. Maybe calling customer service line and calmly describing your issue and dismay at something breaking so soon, and asking if they can make a good will gesture of offering the part for free, then if they don't ask if they would sell at dealer cost. Maybe not what you want, but you might get it fixed for best possible price and you aren't seeing broken part all the time. From past experience in customer service, nice has a better chance, they get enough nasty every day. Good luck, hope it works out.
