Toyota has issued a recall for 2.43 million hybrid vehicles around the world over potential problems with stalling.
The recall applies to 1.25 million vehicles in Japan, 807,000 in the US, 290,000 in Europe and 3,000 in China with the rest across the globe.
The company said in rare cases the vehicles might fail to enter a "failsafe" driving mode, lose power and stall.
Power steering and braking would still work but a stall at a fast speed could increase the risk of a crash.
The recall applies to some Toyota Prius and Auris hybrids made from October 2008-November 2014.
The vehicles were involved in an earlier recall did not fix the previously unanticipated problem which is being addressed now, the company said.
Toyota said it would update the software of the vehicles to remedy the problem for free.
Toyota said it had received three reports in Japan related to the problem by the end of September and reported them to the transport ministry.
The company would not comment on incidents outside Japan, saying it was difficult to be certain about actual cases.
The recall is meant to address situations in which the failure of a specific component, coupled with hard acceleration, could cause the vehicle to lose power rather than enter a failsafe driving mode.
