The owner in question, who Jalopnik refers to as Alec, purchased the car last December. The dealer bought the car a month earlier from a Tesla auction, with both “Enhanced Autopilot” and “Full Self Driving Mode” features intact, according to Jalopnik, which reviewed documents related to the car’s ownership and sale. The dealer then listed the Model S, advertising both features. However, unbeknownst to the dealer, Tesla had independently conducted a software “audit” of the car after selling it, and disabled those features in a December update. The end result: when Alec picked up the car on December 20th, he did not have access to all its advertised features.
