San Francisco. Automaker Nissan has issued a recall notice for approximately 9,813 model year 2023 Ariya electric SUVs in the US due to a possible defect in software related to the drive motor.
According to the US National Highway Traffic Safety Administration (NHTSA), the inverter software can detect a short circuit and shut down the EV system, resulting in a loss of drive power.
According to Nissan, vehicles affected by conductive shavings from the slip rings of the drive motor have the potential to short-circuit the two slip rings.
Due to short circuit, the inverter senses an overcurrent and reduces the motor torque as per fail-safe protocol. When this happens, the vehicle may suddenly shut off, displaying an “EV System Off” notice on the dashboard, Electrek reports.
The automaker first noticed the issue during a production trial in January last year.
Owners of potentially affected automobiles will be alerted beginning October 20. Dealers will update the inverter free of charge to improve processes.
According to the company, this process may take less than an hour.
In August, Nissan issued a recall notice for more than 236,000 small cars in the US due to a potential problem with loss of steering control.
Affected vehicles include certain Sentra compact cars from the 2020 to 2022 model years.
