Bought my Model 3 used from a non-Tesla auto dealership. The advertisement that got mine in the door for a test drive showed the Software screen on the display. Had the Vehicle VIN, Mileage, and then FULL SELF DRIVE, Acceleration Boost and Premium Connectivity. Bought the car on a Thursday and they needed to replace a tire hat had a bulge, so I didn’t take delivery of the car until the following Monday. Since the paperwork for the deal was done Thursday, I had a temporary registration and went on Tesla website to claim ownership of the Tesla and have the account and car in my name so I could now use my phone as a key and use Superchargers. When I got the car Monday and drove it home, I had my wife and kid come into car so I could show them how fun it was. To my shock, the FSD was GONE. All I saw was “Autopilot” on the Software Screen. I asked Tesla what happened and said the dealership messed something up somewhere acquiring the car at auction and they couldn’t help me, and that I need to resolve with the dealership. The dealership blames Tesla and I am now 7 weeks of ownership with a missing/removed $10,000 upgrade. I told the dealership I am certainly entitled to compensation. I am awaiting their reply before I get a lawyer, which will cost me $ I should never have had to pay in the first place.
