Volvo has identified the driver airbags containing FG2 Twin inflators with 5AT 148 N propellant as the issue. Propellant decay over time in certain conditions potentially resulting in critical inflator combustion pressures.

If the airbag inflator propellant tablets are subjected to elevated moisture levels and frequent high inflator temperatures, the tablets can start to decay and form dust particles. A higher burn rate can result in higher combustion chamber pressure and risk of inflator rupture.

In the event of an airbag activation, the driver may be struck by metal fragments from the inflator leading to serious injury or death.

The recall report states that the inflator manufacturer is German auto supplier ZF Friedrichshafen and Autoliv is the airbag assembly manufacturer.
