My Model X (with 22" wheels) has slight door rattles in the front driver and passenger doors, and more pronounced rattles in the passenger side falcon wing door. I just picked it up from the service center to fix the falcon wing door rattles, where they told me it was caused by a loose motor which they tightened and shimmed. Driving it home, the rattles are still there, with new rattles in the front doors. I had a loaner Model S (with 19" wheels) the week it was in the service center and there were no rattles in that car. Anyone else with a model X have door rattles? Am I justified to keep taking it back to the service center until they are gone?
