Had a 48V battery failure yesterday. Since everything runs off it (oil pump water pump AC) all the critical functions shut down to persevere battery life. Warnings on both screens to pull the fuck over right now. Even low beam headlights turned off based on the errors it was firing. No hybrid assist and man this car is laggy as fuck without it.
Parked it for 5 mins, restarted, and everything came back. Stopped by the dealer to scan, saw codes, one time, system checked out fine. They think it's a one time thing, if it comes back they'll take the car in and dig in further.
I'll update once I get stranded.
