Toyota Motor Corp. said Wednesday that 997,000 Prius cars in Japan, some 713,000 in North America, another 130,000 in Europe and the rest in other regions are being recalled for a problem in the software to control the hybrid system.
No accidents or injuries have been reported related to the problem.
The software could cause transistors to become damaged, causing warnings lights to go off, driving power to be reduced or the car to stop. The recalled vehicles were manufactured between March 2009 and February 2014.
The Japanese automaker suffered massive recalls starting in 2009, affecting more than 14 million vehicles for problems including floor mats, gas pedals and brakes.
