NHTSA defect investigations

Federal safety investigators have looked into a possible defect involving the 2018 Mercedes-Benz GLC350 E:

Desiccated Air Bag Inflator Rupture

NHTSA investigation EA21002 · opened Sep 17, 2021 · open

From 2000 through 2017, Takata produced millions of air bag inflators using two types of phase-stabilized ammonium nitrate ("PSAN") propellant -- propellant 2004 and propellant 2004L. After prolonged exposure to high temperature cycles and humidity, inflators using propellant 2004 can degrade, causing the propellant to burn too quickly when ignited.
