Moderator Note: I have done a slight renaming of the thread, and have made a tiny edit to the OP - I moved the section about why it's being called a "computer overheating issue" to the very top, before the description of the owner's issues, so that readers understand this is the specific owner's terminology based on a discussion with a Tesla Service technician.
Kudos.
With that, I'm unsubbing from this thread. Someone ping me if my further input is helpful.
