I have bought my 2017 Model X from a 3rd party dealer and it has enhanced autopilot when I bought and I have used it multiple times for auto lane change. But now I see that the feature is removed after I submitted my ownership change looks like. I have the features list printed when the X was originally bought and has EAP with $5000 cost. Anyone experienced a similar situation? This is frustrating and I wrote to Tesla customer support for help.
