Each time my 2013 S has gone to the shop, it has come back with something updated/upgraded. I gather that there are other things that they'll update if you ask... I wonder what those have been for you? ...and therefore what I might request when it goes back in for scheduled service in March. Mine included AC Compressor mounts and noise suppression cover Steering shims and later higher-torque-spec bolts to correct a squeak Brake rotors (but they still squeak/grunt when coming to a stop) Floor mats. Crazy that they made anti-roll-up mats but they did. Drive unit updates Wire chafing rear wheel well clearance update... Things like that... THANKS!!
