Follow up - Tesla said that it probably needed a "roof rebuild" and that they wont know if it needs a full rebuild until it gets in and they dig into it. They said a full rebuild would cost around $4k. I reminded them that I had the extended warranty, for which their system didnt show. After providing evidence, magically the estimate dropped down to $1400 if it wasn't covered under the extended warranty...hmm? After rescheduling the repair 3 times now due to parts not being available, I am scheduled to drop it off next week Thursday (barring any additional parts delays). I will send an update when I learn more.
