It's probably not a new car, but the system.
My vin automatically unlocked on the website T-7 days from delivery; about the hour of my delivery appointment. The next day when I called my service center they told me a logistics issue kept the car from arriving on time, and moved me a week back to a new date. That change hid my VIN again. I know it's the same car/vin though. (My car, despite being delivered in Pittsburgh, was only loaded onto a train at 12:00AM on 9/14,,, if they make it by 9/25 like they say, i'd be amazed)
