Recall 20V374 affects 114 2020 Ram Promaster vans and 1500 pickups for a side-curtain-airbag diffuser defect. Repair is free at any franchised Ram dealer.
Ram is recalling 114 2020 Promaster vans and 1500 pickups under recall 20V374 because an improperly crimped diffuser in the side curtain airbag can detach from the inflator during deployment. That failure can keep the airbag from inflating properly and raises the risk of injury in a crash; the Ram dealer repair will be free once available.

What's wrong?
The side curtain airbag in the 2020 Ram Promaster and 1500 sits along the roof edge and helps protect occupants during a side impact or rollover event. Its inflator fills the curtain with gas in a fraction of a second, and the diffuser is the outlet piece that controls how that gas enters the airbag.
On affected vehicles, the diffuser was not crimped correctly to the inflator. The crimp is the mechanical squeeze that holds those parts together. If the side curtain airbag deploys, that weak connection can let the diffuser detach from the inflator instead of staying locked in place.
There is no warning sign before failure. An owner will not hear, feel, or see this problem during normal driving because it only shows up during an airbag deployment.

- Reference recall number 20V374 and Ram recall W52 when you call.
