Update: I picked up the car today. They had to replace the AP4 car computer, multiple coolant purges were performed, latest firmware downloaded and installed. Version: 2023.44.30.7. They test drove the car to see if all features were working as they should and they confirmed everything was working.
I picked up, test drove, it's all working fine now. Turned on Sentry Mode as soon as I get home after the drive from the SC.
I dont expect it to malfunction just because of the Sentry Mode being turned on but we'll see.
Aside from the long wait, a month to be exact, of sometimes frustrating situations, time-consuming research on how to possible remedy the problem, the experience with Tesla Repair Services were great!
