On the 2023 Toyota bZ4X, 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.

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.

This issue also affects: Nissan Ariya, Fiat 500e, Mazda MX-30

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.

TipDrive on the highway for 20-30 minutes before hitting a DCFC in cold weather. The battery needs to be above 60°F for decent charge rates. Pre-conditioning through the app while plugged in at home also helps.
