It is mind boggling that you had freshly replaced HVBJB fail....My car never had a 12V battery issue. It was the HV system that flaked out each time.
The likelyhood of your original, AND replacement HVBJB containing bad contactors seems remote.
Leaving a higher chance of a bad connector, wire harness, or 12v connection failing to send enough 12v to hold the contactor relays properly... allowing arcing, and welding internally.
Do you know whether the Service team removed and examined the wiring and connectors as well as the HVBJB? In particular the harness from HVB to dc-dc, and dc-dc to 12v panel, and 12v panel to 12v battery?
