However in a doc posted Wednesday within the Federal Register and dated Dec. 13, the company stated it thought of feedback on a call from January in search of the recall. The auto trade pointed to technical and engineering variations between ARC inflators in autos made by completely different producers.

“To make certain, the overwhelming majority of the topic inflators won’t rupture upon deployment,” NHSTA wrote in January. “Nonetheless, based mostly on the proof linking previous ruptures to the identical friction welding course of, the entire topic inflators are susceptible to rupturing.”
However a number of automakers argued in public feedback that years of investigations by NHTSA didn’t set up a systemic design defect. Some stated not one of the hundreds of thousands of inflators of their autos have ruptured as a result of trigger identified by the company.
