All 3 Known Issues
Early 2023 bZ4X models were recalled for hub bolts that can loosen during driving, potentially causing wheel detachment. The hub bolts can lose torque due to a manufacturing defect. Toyota halted sales and issued recall 22V-651 with a stop-drive notice.
Common Symptoms
- Clicking or clunking noise from wheels
- Steering wheel vibration
- Vehicle pulling to one side
- Visible wheel wobble
- Hub bolt torque loss on inspection
How to Fix
This is covered under recall 22V-651 at no cost. All hub bolts are replaced with redesigned bolts and retorqued. Toyota dealers will inspect and replace all hub bolts. Do NOT drive the vehicle if you suspect loose hub bolts - contact Toyota for towing assistance. Re-torque hub bolts at every tire rotation as maintenance.

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.

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.
