Tesla owners are reporting that old contracts mentioning the company’s Full Self-Driving (FSD) feature have been quietly changed. Electrek reports that it confirmed with multiple Tesla owners that purchase agreements for the FSD feature signed between 2016 and early 2024 now include “supervised” language. In some cases, owners say the original documents are also no longer accessible online. Oliver Abcarius, who owns a 2018 Model 3, told Electrek that he bought FSD for his car in 2019. He recently tried to pull up the purchase agreement while preparing a refund case and noticed that the document had been renamed “Full-Self Driving (Supervised) – August 12, 2019.” But when he tried to open the document, the link led to an invalid page, according to a screenshot published by Electrek. The catch is that Tesla did not start using the “supervised” language for the feature until 2024.

“Tesla has retroactively updated my documents from 2019 when I paid for FSD,” Abcarius told Electrek. “Back in 2019 Tesla did not contain ‘supervised’ language in the purchase agreement. I can no longer actually open the document as it links to an invalid page.”

Abcarius said the same thing happened with documents for his wife’s 2020 Model Y, which was bought with FSD. He said the “Motor Vehicle Purchase Agreement” is no longer accessible. According to Abcarius, the couple’s other Tesla documents are still available, but the documents that would include details about their FSD purchases are not. Electrek says it confirmed that other owners of HW3 Teslas, an older version of Tesla’s self-driving hardware, have run into the same issue.
