Just recently purchased a '21 M3LR, only 15k miles on it. The bottom of the driver's seat isn't attached so that whole plastic section w/ the seat controls flops around loose; there's what sounds like a screw that's fallen out inside the passenger door; and the driver's seatbelt adjustment by the shoulder doesn't work at all, can't move it. Put in a service request via the app and they're giving me an estimate of ~$500. This should definitely be a warranty issue, yes?
