I did the transfer and bought a new Y HW4 last Saturday August 19th. I still have NOT received confirmation that the transfer happened, even though calls to the Service Center and Delivery Center tried to assure me that it did. I do NOT see any thing on my software tab to indicate it has did as promised. I only have a note that the FSD I now have is good for 3 months only, or just the promotional version new buyers were supposed to get. I have an Agent at the Delivery Center supposedly working on the issue, but still noting. I would be very skeptical of the Tesla promise. I wished I knew who to escalate this problem with at Tesla as the Service Center and the Delivery Center have NOT been able to solve it. Anyone have any suggestions?
