When both key fobs failed today, I could still access the vehicle with the smart phone. That's not the topic of this thread. When I called Tesla Roadside Assistance and gave them my Model X Signature VIN, the reply was not what I expected. My vehicle was listed with a completely different owner name in the Tesla Motors computer. He read back the full VIN and it was the same as the dash screen. They only saw my 3 year old Model S when looking up my name. After some time, they did check the "My Tesla" screens and saw the VINs for both Model S and X. The Tesla person said they would look into the issue of the incorrect data. IMHO, my suggestion is to give Tesla a call after your Model X Signature delivery to check if your information is current.
