All 3 Known Issues
On the 2023-2025 Toyota bZ4X, the bZ4X's DC fast charging peaks at approximately 100kW but quickly tapers to 40-60kW, making charging sessions significantly longer than competitors. Cold weather reduces charging speed further, and the battery thermal management system is less aggressive than rivals.
Common Symptoms
- DC fast charging slower than expected
- Charging speed drops quickly above 30% SOC
- Very slow charging in cold weather below 40F
- Charging sessions take 60+ minutes for 10-80%
How to Fix
Pre-condition the battery before DC fast charging by using the climate control while driving to the charger. Toyota released OTA software updates improving charging curve management. Charge at higher power stations (150kW+) to maximize the initial charge burst. In cold weather, plan for significantly longer charging times. Level 2 home charging overnight is the most practical daily charging method.

On the 2023-2025 Toyota bZ4X, the bZ4X experiences 30-45% range reduction in cold weather (below 32F/0C), dropping from the EPA-rated 252 miles to 140-175 miles in winter conditions. The heat pump system helps but cannot fully compensate for battery efficiency loss and cabin heating demands.
Common Symptoms
- Range estimate drops dramatically in cold weather
- Actual range 30-45% less than EPA rating in winter
- Battery SOC drops faster in cold temperatures
- Climate control uses significant battery energy
How to Fix
Use scheduled departure to pre-condition the cabin and battery while plugged in (this uses grid power, not battery). Set climate to Eco mode and use heated seats/steering wheel instead of cabin heat when possible. Maintain tire pressure (cold weather drops PSI). OTA updates from Toyota have improved energy management. Plan routes with 30% extra range buffer in winter.

On the 2023-2025 Toyota bZ4X Electric Motor, the bZ4X exhibits dramatically reduced DC fast charging speeds in cold weather (below 40°F/4°C), sometimes charging at only 6-15 kW on a 150 kW charger. The battery thermal management system aggressively limits charging current to protect the battery, but owners report charging sessions taking 2+ hours for a 20-80% charge in winter. Pre-conditioning via the app helps but doesn't fully resolve the issue.
Common Symptoms
- DC fast charging at 6-15 kW instead of 100+ kW
- Charging sessions taking over 2 hours
- Battery temperature warning on dashboard
- Estimated charge time showing excessive duration
How to Fix
Use the Toyota app to pre-condition the battery before arriving at a DC fast charger. Drive at highway speeds for at least 20 minutes before charging to warm the battery pack. In extremely cold weather, consider using Level 2 (AC) charging overnight instead. A software update (TSB T-SB-0109-23) improved cold-weather charging algorithms but didn't eliminate the limitation.
