On 25th April 2019.
I found the news article that NHTSA(National Highway Traffic Safety Administration) in USA started the investigation about defected airbags on Hyundai/Kia, Toyota, Honda, Mitsubishi, FCA Chrysler. It claims that there were about 10 times incidence of death due to the airbag malfunction during collision. The airbags are produced by TRW in USA.

KATRI(Korea Automotive Testing and Research Institute) also started preliminary investigation on TRW airbags which are installed in the imported cars such as Toyota and Honda.

According to KATRI, there will be a possibility of defect because the base board of airbags which has been provided to Hyundai/Kia cars are produced by TRW and Hyundai MOBIS just assemble the parts on the board.

However Hyundai/Kia states that it’s not related with USA airbag defects since domestic airbags are different with export airbags to USA.
