Both Toyota and Nissans airbags have been produced by Takata.

Toyota Motors and Nissan Motors announced on Wednesday they are recalling over 6.56 million vehicles from across the world after discovering a fault on air bags made by Takata.

The recall by Toyota of roughly 5 million vehicles globally affects cars produced between March 2003 and November 2007, spanning 35 models. The number of cars affected in Europe is in the region of 1.2 million and 637,000 in the U.S. Some of the models which are affected include the Toyota Yaris, Corolla, Rav4, Hi-Lux and Avensis models.

Nissan made a separate announcement recalling 1.56 million vehicles which were manufactured between 2004 and 2007. Nissan has said this will affect 326,000 vehicles in North America, 563,000 in Europe and 288,000 in Japan.

These recalls are in addition to 25 million vehicles which have already been recalled by more than 10 auto makers due to Takata air bags. The faulty air bag has been link to at least six deaths due to air-bag explosions.

“Among the parts collected from the Japanese market, certain types of air-bag inflaters were found to have a potential for moisture intrusion over time,” Toyota said in a statement. “As a result, they could be susceptible to abnormal deployment in a crash. The relationship of moisture intrusion, if any, to the risk of inflater rupture is not known.”

The airbags contain propellants used to emit gas which fill up the air bag however if moisture can seep into the air bag inflaters is can let gas out too quickly causing the metal casing to explode. High risk users are those in humid climates prone to moisture in the air. Acorrding to industry experts Takata uses ammonium-nitrate based propellants, which is sensitive to moisture. Toyota plans to replace defective air bag inflaters with ones made by Daicel which do not use ammonium-nitrate.

Takata was threated with legal action last year by the US National Highway Traffic Safety Administration when it advised there was no need for a recall as the issue was just an anomaly.

An official for Japan’s Ministry of Land, Infrastructure, Transport and Tourism said:

“The recalls are made by auto makers as a pre-emptive measure…there have been no reports of any new accident”

A spokewomen for Takata said it “will give full cooperation to the auto makers.”

Takata faced challenges last year with a ¥29.6 billion net loss in the 12 months to March 31 and this may scupper the companies plans to return to profit this business year ending March 2016. Takata had forecasted a net profit of ¥20 billion ($170 million) this fiscal year due to a solid rebound in demand although this may dent projections.
