Only problems with LiFePO4 is if you charge them much below freezing the batteries capacity is severely damaged then if the battery is discharged while above 120F it's rapidly damaged. Between a winter and a summer improper use could kill over 1/3 of the batteries capacity.
The operational temperature range between too hot and too cold is only around a 100F span.
So LiFePO4 batteries need a lavish and robust thermal management system that can have a lot of energy directed towards it, really plug in hybrid are the application for them since the battery isn't depended on and the engine can be fired up to heat or cool the battery and drive the car as needed.
They're also cheap and don't use any of that slave mined cobalt.

The batteries the leaf uses are much more robust.
The do not charge low temperature cut off is around 0F but may be as low as low as -4F, they will charge at +10F slowly and the upper limit is more like 130F.
Rapid high temperature damage like you see in the LiFePO4 doesn't happen with the LiNiMnCo02 until above 140F.
The LiNiMnCoO2 battery comfort range is more like a 120F span. But they explode if they get poked.
