my model S 60D September 2016's heated steering wheel suddenly stopped working. I've rebooted both screens, tried toggling settings on and off, nothing I do seems to work. Could it have really gone out this quickly? I have a service appointment in the first week of April for my 12,500 service so I can get it looked at then, but I'm also considering trading up to a AP2 model in which case I'm going to forgo the service but I'd like to sell it with everything working so if there is a fix I'd like to do it without a service appt. anyone with any experience?
