The defect
Chrysler (FCA US LLC) is recalling certain 2020 Ram Promaster vans and 1500 pickups. The affected vehicles may have an improperly crimped diffuser in the side curtain airbag which may result in the diffuser detaching from the inflator in the event of an air bag deployment.
The risk
In the event of a crash, if the diffuser detaches from the inflator during air bag deployment, the air bag may not inflate properly, increasing the risk of injury.
