If I remember right the subcodes for P1449 are battery deterioration, battery deviation, and battery overheat. The first time my car threw P1449 was after a long down hill stretch with constant regen, so I think that might have been an overheat code, but I didn't know about the subcodes so I didn't check. The second time I was able to check and it was battery deterioration, and the code was set right after the car quickly exhausted what it believed to be a nearly full pack, so that would make sense. If I were to allow assist to function normally again it would do the same thing in short order.
As I understand it, the P1447 code is for battery degradation and is more likely to point to one or more damaged cells in the pack, which makes me optimistic that mine could be saved by rebalancing.
