A few days ago my Model X from March 2017 with EAP lost its Autopilot features. It never seems to become available anymore as I'm driving. Navigate on Autopilot doesn't show when I set navigation. The steering wheel icon that shows next to the speedometer in the center display never comes up anymore. When I try to engage Autopilot or cruise control from the steering wheel stalk, it says "Cruise control unavailable". A few days ago everything was working fine. Any ideas? I made a service center appointment but it is a week away.
