Toyota´s recall affects all third-generation Prius' manufactured after 2009.
Toyota, the world's biggest carmaker, on Wednesday said it has discovered about 400 faulty vehicles in the world, mostly in Japan, adding; “No accidents and injuries have been reported over the software fault.”
The first generation Prius was first released in 1997.
The warning lights can be set off by Toyota´s Prius software problem and may cause the vehicle to enter a failsafe mode, which will see the car's driving power reduced.
The top-selling global carmaker said the car system can shut down and the vehicle will stop, perhaps while being driven.
