In a significant development, FAW Toyota, the joint venture between Toyota and FAW Group in China, has announced the recall of 25,815 bZ3 electric vehicles (EVs). This recall, the first since the bZ3’s launch in April, is prompted by issues related to the power battery management controller. The recall, effective immediately, encompasses vehicles produced between March 13 and November 9.
Details of the Recall
FAW Toyota’s swift response to the issue highlights the commitment to consumer safety. The recall addresses a specific problem: the improper program of the power battery management controller, resulting in an excessive deviation in the remaining power estimation. This becomes apparent when the vehicle hasn’t been fully charged for consecutive occasions and is driven at high speeds.
Power Estimation Deviation
Understanding the technical aspect, the deviation in remaining power estimation poses risks, especially when the vehicle is not fully charged. In such cases, the displayed remaining battery charge exceeds the actual amount. In extreme scenarios, this discrepancy leads to power loss before the charging warning light activates, raising concerns about on-road safety.
Safety Hazards and Solution
To rectify this issue, FAW Toyota plans to upgrade the control program through Over-The-Air (OTA) technology. This crucial update, provided free of charge, aims to eliminate the safety hazard associated with inaccurate power estimation. Owners of the affected bZ3 vehicles are urged to respond promptly to ensure their vehicles receive the necessary upgrades.
Background of Toyota bZ3
Unveiled in China on October 25, 2022, the bZ3 holds significance as the second model in Toyota’s bZ series, following the bZ4X SUV. With pre-sales starting on March 6 and official sales commencing on April 16, the bZ3 is positioned as a mid-sized electric sedan based on Toyota’s e-TNGA architecture.
Measuring 4,725 mm in length, 1,835 mm in width, and 1,475 mm in height, with a wheelbase of 2,880 mm, the bZ3 boasts electric motors and blade batteries supplied by BYD.

With a single rear-mounted motor available in 135 kW and 180 kW options, the bZ3 accelerates from 0 to 50 km/h in just 3.2 seconds.
In spite of the recall, sales of the bZ3 were consistent. November saw a 2.17 percent increase in wholesale sales to 3,065 units from the previous month. Information from the China Passenger Car Association (CPCA) clarifies how the model performs in the cutthroat market for electric vehicles.
To sum up, the bZ3 recall highlights how electric car technology is always developing and the proactive steps manufacturers are taking to address possible safety issues. The industry’s commitment to consumer safety is demonstrated by FAW Toyota’s upgrade of the control program.
