Known issues

High
Polestar 2 had a 2022 recall (Recall 22V-678) for inverter software causing loss of drive power; addressed via OTA. Pack hardware itself was not implicated.
High
Volvo XC40 Recharge and C40 Recharge share the pack and inverter. Same software-related no-power events on early builds; resolved via dealer reflash.
Low
Cold-weather range loss is consistent with NCM pouch; expect 25-30% reduction at 20°F. Heat-pump option (introduced 2023 in Polestar 2) materially improves winter range.
