It has never happened to me but from reading this group for the last couple of years my understanding is that the car is trying to protect its battery from some unusual event. If it isn't just a software bug then it will be something like driving very hard when the battery is nearly drained. Or perhaps the temperature is extreme (unlikely at this time of year). Best practice seems to be to give the car a rest for a bit when you can.

Was this a fleeting indication or something that persisted?

Is that the 12v battery or HV pack?

hv pack

Makes sense, given your initial post, looks like you had a ‘weak’ cell that activated ‘tortoise mode’.
How long was the car in the garage?

Not bad, diagnosing a HV battery issue and replacing it used to take months..
