American regulators announced today their initial finding that vehicles equipped with 52 million airbags made by ARC and Delphi should be recalled. The decision will be followed by a public meeting where a final decision on a recall will be reached.

The recall relates to vehicles equipped with ARC-designed airbags that were produced between 2000 and 2018. Seven injuries, among them one fatality, relating to an alleged manufacturing defect have been recorded in the U.S., according to the National Highway Traffic Safety Administration (NHTSA).

The fault occurs when the airbags expand, which can cause excess welding slag to be blown off the inflator and into vehicle occupants, increasing the risk of grievous injury. NHTSA recommended a recall earlier this year, but ARC declined, claiming that the incidents were so infrequent that they do not “support a finding that a systemic and prevalent defect exists.”

NHTSA counters that it has precedent for calling such a recall, thanks to the Takata airbag incident. It added that “airbag inflators that rupture when commanded to deploy are plainly defective, as they both fail to protect vehicle occupants as they should, and, themselves, pose an unreasonable risk of serious injury or death.”

Despite ARC’s resistance to a recall, the airbags it (as well as Delphi, under license) made have already been recalled by at least four automakers. General Motors was among them, and agreed to fix nearly 1 million vehicles over their use of the airbag in May, following an accident in March that led to facial injuries for the driver.

In addition to GM, another 11 automakers used the airbags in their vehicles, including Ford, Hyundai, Mercedes, Tesla, Porsche, Stellantis, Toyota, and Volkswagen. Although it previously estimated that there were 67 million airbags to recall, NHTSA says that it now believes that some automaker overreported their numbers, and just 52 million airbags are in the field.

To determine if they should be recalled, a public hearing will be held October 5. There, ARC and other interested parties will have an opportunity to present their cases, after which, NHTSA will decide whether or not to compel the manufacturer to file a notice of the safety defect, which will lead automakers that used the part to recall subject vehicles.
