TOKYO - Toyota on Wednesday announced a global recall of 1.9 million of its signature Prius hybrid cars, dealing a blow to a brand favoured by the eco-conscious including Hollywood celebrities.
The company said it decided on the call-back -- its biggest-ever for the vehicle -- after the discovery of problems with software used to control a power converter that posed a risk to drivers.
"Because, in the worst case, the car could stop while driving we do consider this a potential safety issue and that's the reason why we are implementing this recall," a Tokyo-based company spokesman said.
No accidents have been reported as a result of the defect, the world's biggest automaker said.
The Prius was one of the first hybrid cars to go mainstream and was quickly adopted as a symbol of green, with the likes of Leonardo DiCaprio and Cameron Diaz snapped behind the wheel.
The company recalled Prius models last year and in 2010 for different problems, but Wednesday's announcement marked the biggest call-back for a car that Toyota has bet will lead a bigger move to green cars.
