Users in Canada and the northern US reported that an estimated 400km range could drop to roughly 230km (about 140 miles) in winter, often seeing "range melt" in temperatures below 0∘C0 raised to the composed with power C 32∘F32 raised to the composed with power F

Note: For the 2025/2026 model year, the car has been updated and renamed simply to the "Toyota bZ" in some markets. Users in Canada and the northern US reported

Later models and specifically the 2026 refresh are designed to address these, with improved battery management, faster charging, and a better heat pump. The car manages its battery conservatively, which can

Owners found that parking in a garage, using the "Eco" heat mode, and using the cabin pre-heating feature while plugged in helped mitigate some losses. The car manages its battery conservatively

The car manages its battery conservatively, which can exaggerate the feeling of range loss when the battery is actually near empty.

The 2022 Toyota bZ4X (and early 2023-2024 models) is well-documented for experiencing significant, visible range loss in cold temperatures, with some users reporting reductions of 40-50%. While all EVs lose range in cold weather, this model specifically struggled with battery chemistry management, HVAC energy consumption, and charging speeds in freezing conditions.
