Toyota is issuing a safety recall for around 625,000 Prius hybrids globally due to a software glitch that can result in the hybrid system shutting down while the car is running. Currently, there are no crashes or injuries reported due to this issue.
According to the automaker, the glitch is caused by a software setting for the motor/generator control ECU and the hybrid control ECU that can cause excessive thermal stress on the transistors which can result in damage. If damage does occur, the vehicle can notify drivers via warning lights while entering failsafe mode. However, in some cases the damage could lead to loss of power and the vehicle shutting down while in motion.
Around 120,000 of the recalled vehicles are in North America with 160,000 in Europe and the remaining 340,000 in Japan. About 109,000 of the models are Pruis V minivans built from May 2010 through November 2014. This model is called the Prius Plus in Europe and the Prius Alpa in other markets.
The recalled models will be updated at Toyota dealerships who will fix the software for the motor/generator control ECU and the hybrid control ECU.
