That's awesome, congrats. Great to see more white interiors coming. In my case, my financing expired and I was never notified nor did my account ever change. I also haven't gotten a VIN yet, and I just so happened to be chatting with Tesla support the day after it expired when they told me that and that I would need to renew it.
I've learned to always be proactive when it comes to this process, but I'm sure they would catch it at some point if you didn't feel like reaching out to them to get it renewed. Be prepared to get a worse rate though. I had 2.59 with chase originally in March, then they renewed it with US bank and I got 2.99%. I emailed Tesla Finance and had them check it again with chase and ended up with 2.29 in the end.
