Toyota Motors has issued a massive recall for the third-generation Prius, which is sold around the world, according to Reuters.
The recall affects 1.9 million Prius vehicles.
Toyota said the issue was in the software used to control the boost converter in a module that is part of the hybrid system.
"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.
No accidents have been reported related to the issue at press time.
In some cases, the hybrid system can shut down, which causes the vehicle stop suddenly, possibly while it's being driven, according to Toyota.
"This will result in various warning lights being illuminated, and will probably cause the vehicle to enter a failsafe mode," it said, noting that the car can be driven but with reduced driving power.
This is the third recall for the current Prius model. The last recall was announced back in June 2013 due to an issue with the brake accumulator.
The Prius is annually one of the top-selling vehicles in the world.
Toyota has yet to announce the cost estimates for recalls.
