Japanese airbag manufacturer Takata and several carmakers that used its products are being sued in the US over allegations they sold unsafe vehicles.
The class action lawsuit comes after millions of cars were recalled over potentially dangerous airbags.
It claims Takata and automakers such as Honda and Toyota hid the alleged airbag defects from consumers.
At least four deaths and more than 30 injuries in the US have been linked to faulty airbags made by Takata.
The airbags can potentially spray deadly shrapnel at passengers if deployed with too much force.
Honda and Toyota are among the carmakers named as defendants in the case, which was filed in a US district court in Florida on behalf of consumers across the country
The lawsuit said Takata “had a duty to disclose these safety issues because they consistently marketed their vehicles as reliable and safe”, Reuters said.
