Mine does same rattle since 22miles. Cannot figure it out . I have 6,000 miles now. I checked the bins, the seats, the headliner. Seems to be coming from rear pass side door between front and back pillars. My seat makes noises on passenger side, adjustable headrest vibrates too but it's a different noise. The door area rattle sounds like window is rattling or inside lock mechanism rattling . I'm stumped as to the exact source of the rattle noise. I am sure that it's coming from inside vehicle though. ??????
