Japanese car giants Toyota and Nissan are recalling a total of 6.5 million cars globally to replace potentially faulty airbag inflators made by Takata.
Toyota said it was recalling just under five million cars, including the Corolla, Vitz and other models made between March 2003 and November 2007.
Nissan is recalling about 1.56 million cars over the same issue.
Both carmakers said the recall was for investigative purposes and no accidents or injuries have been reported.
Toyota, the world's biggest carmaker, said the recall affected 35 of its models made around the world and that it would include 1.36 million cars in Japan.
The move is the latest in the saga of potentially exploding airbags made by Japanese car parts maker Takata that has been linked to at least six deaths - all in Honda cars.
