I don't think it's your battery. Looks to me it's your drive unit (DU).
**** ... another 10 grand. Hopefully not.

Which code would indicate the DU?

It looks like the BMS codes happened while it was serviced.

BMS_f033
The Battery Management System (BMS) will trigger this alert when it senses a loss of contactor power while the contactors are closed. The BMS assumes that it could be because the pyro fuse on the contactor power supply signal blew during a crash.

This may trigger while a vehicle is in Service and the contactor power supply loop has been pulled.

BMS_f062
The Battery Management System (BMS) has detected that there is a power supply issue with the contactor.

It happened while my wife was driving. Completely shut down. Hopefully it’s not the DU. I can’t afford another 8-10k. Luckily they gave me a loaner. The least they could do. Do you all think it was something different all along??
