I brought my car to brooklyn tesla service because my driver seat started to rocking (its moving like it got loose) after technician duplicated the issue, he said it's a "normal wear and tear" and that tesla seat can start moving after a certain time if the driver is heavy. they refused to do anything i am concerned about safety and i'm sure that loose driver seat is dangerous. in addion the seat has metal bar on buttom cusion that is paintfull for "heavy" drivers, also a very big safety concern because you can't really drive in pain and this as per tesla the seat is designed this way.
