Toyota Motor Corp. has announced a recall of approximately 1.9 million Prius hybrid vehicles due to a software problem that could cause the vehicle to stall.

A glitch in the hybrid system software could cause transistors to become damaged, causing warnings lights to go off, driving power to be reduced, or the car to stop.

"The setting of the software could cause higher thermal stress in certain transistors within the booster converter, and these transistors could deform or become damaged as a result," Toyota said in a statement.

This recall affects all the third-generation Prius cars sold worldwide, including roughly 713,000 vehicles in North America.

All of the Toyota Prius vehicles included in this recall were manufactured between March 2009 and February 2014.

Toyota will notify owners and dealers will update the software for both the motor/generator control electronic control unit (ECU) and the hybrid control ECU, free of charge. If an owner experiences a failure of the inverter before the vehicle receives updated software, the dealer will replace the inverter assembly with a new one at no charge.
