The article doesn't really explain the safety issue. Here's a run-down: https://www.caranddriver.com/news/a45474173/nhtsa-52-million-arc-airbag-inflators-call-for-recall/ https://www.caranddriver.com/news/a45474173/nhtsa-52-million... And here's the initial decision in full: https://www.nhtsa.gov/sites/nhtsa.gov/files/2023-09/ARC-Initial%20Decision-9-5-23-signed.pdf https://www.nhtsa.gov/sites/nhtsa.gov/files/2023-09/ARC-Init... Apparently friction welds left "excess slag" on a seam in the inflator. During activation, bits can become dislodged and clog the exit orifice such that it explodes with excess pressure "shooting metal shrapnel into the occupant compartment". Affected inflators were manufactured before ARC started using borescope inspection in early 2018, and were installed by several major auto manufacturers. One driver was killed after a crash in a 2015 Chevrolet Traverse in which metal shards flew out. All other drivers, including one passenger, were injured primarily in the face. A second driver was killed in a 2009 Hyundai Elantra during a 2016 crash in Canada, while a passenger-side airbag inflator ruptured in Turkey a year later on a 2015 Volkswagen Golf that used an ARC inflator built in Tennessee. Manufacturers argue these are isolated incidents but NHTSA predicts future ruptures at a rate of 1 in 370,000.
