Battery Fault (self corrected) on 1 week anniversary

[cgfrndpor]

Drove a short distance, parked and shopped. On returning "battery fault' error appear and car would not budge (stayed in P)
Shut down, locked and put key in Faraday pouch. Only waited about 5 minutes (instead of the recommended 15) and things returned to normal.

From what I've read this doesn't leave anything in the car history, so I will just ignore for now.
Question: based on others experience am I headed down the road to 'ruin'? Or can I be comfortable with this as a one-time glitch.

2021 4S; supposedly updated for software.

Any information would be much appreciated.

The 2020 update of the car and charger was going to fix the 12 volt battery draining problem. What I understood, the main battery charging process caused the 12v battery to drain. It's important therefore to have the charger updated at the same time because it blocks the discharge.
