&Sydney, February 28 the federal government of Australia announced a mandatory recall of 4 million vehicles equipped with lethal Takata airbags on February 28. According to Australian media reports, this will be one of the largest and most important product recalls in Australian history, with an average of two out of seven vehicles recalled. &It is understood that some industrial ventilation fan manufacturers airbags produced by Takata company in Japan have fatal defects, which may become "throat cutters" under certain circumstances, rather than life-saving grasses. The ammonium nitrate propellant used in the gasbag cannot isolate moisture in a humid environment. Once in a humid environment for a long time and the temperature changes repeatedly, ammonium nitrate will burn violently, causing the airbag to burst and eject metal fragments, causing serious casualties. At least 23 people have been killed and 230 injured worldwide due to metal fragments piercing their eyes, neck and chest. Last year, a man in Australia died of a defective takada airbag and another woman was seriously injured. &Since 2009, some Australian auto suppliers have voluntarily recalled cars that use dangerous Takata airbags. As of January 2018, only about 1.7 million of the 2.7 million vehicles that need to be recalled had their airbags replaced. &In this regard, Australia and AustraliaMike suka, deputy finance minister of Asia, said the voluntary recall was generally unsatisfactory. He said the scope of the mandatory recall would be expanded, with an additional 1.3 million vehicles recalled in addition to the 2.7 million previously voluntarily recalled vehicles. The 1.7 million vehicles that have had their airbags replaced also need to be checked again. &Rod industrial air curtain supplier Simms, chairman of the Australian Competition and Consumer Council, said all dangerous airbags must be replaced by the end of 2020. At present, the biggest explosion risk is an airbag called alpha, which needs to be recalled first. In addition, he said not all takada airbags are lethal. &The mandatory recall will involve 25 automobile manufacturers, including Ford, general motors, Mercedes Benz, Tesla, Jaguar, Land Rover, Volkswagen, Audi, Skoda, BMW, Chevrolet, Chrysler, Dodge, Ferrari, jimsy, Honda, jeep, Lexus, Mazda, Mitsubishi, Nissan, Subaru, Toyota and Wal Mart Wo and Hino trucks. The cost of the recall will be borne by the car manufacturer. &It is reported that in 2016, Takata airbag incident became the largest vehicle safety recall in the history of the United States, with more than 40 million vehicles recalled. In shop now June 2017, Takata applied for bankruptcy protection. In September 2017, China's General Administration of quality supervision, inspection and Quarantine (AQSIQ) announced that due to the potential safety hazard of Takata air bag, Volkswagen (medium)China) Sales Co., Ltd., FAW Volkswagen Co., Ltd. and SAIC Volkswagen Co., Ltd. have decided to recall some vehicles in batches, totaling 4.86 million vehicles, starting from March 12, 2018.
