Did Ford address the battery thermal management issues reported on the 2021-2022 Mach-E in the 2023 model?
Ford deployed an over-the-air (OTA) software update for the 2023 Mach-E that improves battery thermal management in cold weather. The battery pre-conditioning routine now activates more aggressively when the navigation system detects an upcoming DC fast-charging stop. In real-world Canadian use at -20°C, 2023 owners report a marginally lower winter range penalty — roughly 30 to 35% versus 38 to 42% on 2021 units. Activating the cabin and battery pre-heat via the FordPass app while still plugged in remains the single most effective strategy to maximize usable range on cold Ontario or Quebec mornings.
