Japan car makers recall millions of cars over defective airbag

Japan's top four car makers are recalling a total of  3.4 million cars over a defect in passenger airbags.  

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. 

Globally, Honda is recalling 1.13 million cars, Nissan almost 500,000 and Mazda 45,000.  

In the UK, Toyota, Nissan and Honda are all recalling certain models. The cars were sold between 2000 and 2004.
