The prior owner of my 2017 453 Prime Cabrio hit something with the oil pan which also cracked the upper oil pan. The dealer replaced the steel oil pan and the upper aluminum part of the pan which required pulling the engine and transmission. Now I notice that at low speeds there is a plastic sounding rattle coming from either the left quarter panel or the rear of the driver's door. The noise is most apparent the the top is down and the roof pillars are removed. Has anyone experienced something like that and were you able to fix it? The repair took over a month so the rattle may have been there before and I just don't remember it.
