Toyota is recalling 2.4 million hybrid vehicles worldwide. More than 800,000 of the affected cars are in the U.S.
The recall includes 2010-2014 Toyota Prius and 2012-2014 Prius v vehicles.
Toyota says the issue is in the vehicle's failsafe feature, which is supposed to automatically idle the car so it can get to the side of the road. But Toyota says in "rare situations" the feature hasn't functioned, causing the car to lose power and stall. The company warns that while power steering and braking still function in the failsafe mode, it could increase the risk of a crash.
Toyota says the affected cars have already faced two previous recalls in February 2014 and July 2015 for separate issues.
And last month, Toyota issued a safety recall for more than 1 million hybrid vehicles because of an electrical issue that could cause the cars to catch on fire.
