Japan's top four carmakers are recalling 3.4 million cars globally over a defect in passenger airbags, BBC News reported.
Toyota, which is recalling 1.73 million cars, said the vehicles had a defective part which "could cause the airbag inflator to rupture and deploy the airbag abnormally in a crash".
Honda Motors is recalling 1.13 million cars, while 480,000 of Nissan's and 45,000 Mazda cars are affected.
The firms said the defective part was supplied by parts maker Takata Corp.
Shares in Takata fell 9% to 1,819 yen on the Tokyo Stock Exchange on Thursday, April 11.
Ryo Sakai, a spokesperson for Toyota, told the BBC that the firm had received reports of five separate incidents of the airbag inflator being ruptured.
Two of these incidents took place in Japan and three in the U.S., Sakai said. However, he added that there had been no injuries as a result of the incidents.
Meanwhile, Honda, Nissan and Mazda said that there had been no incidents involving their cars.
All four carmakers have said that they will replace the defective parts for free.
"We are conducting a voluntary safety recall to address this issue and replace the front passenger bag inflator," a spokesperson for Nissan told the BBC. "We plan to notify the customers over the next 30 days," he added.
