Toyota recalling about 701,000 Gen 3 Prius vehicles in US over software issue in inverter assembly

Green Car Congress

The inverter converts high-voltage direct current (DC) stored in the high-voltage (HV) battery into high-voltage alternating current (AC) for the motor/generator. It also converts AC into DC during regenerative braking for storage in the HV battery. No other Toyota or Lexus models are affected, according to the company.
