Fiat Chrysler Automobiles is recalling 3,514 2018 Ram ProMaster vans because the front-door impact sensors may malfunction and lead to air bag failure, according to the National Highway Traffic Safety Administration.

In these vehicles, an incorrect rivet may have been used to attach the front-door impact sensors. As a result, the sensor housing might fracture and hinder deployment of the standard supplemental side air bags during certain side-impact crashes, NHTSA said.

Ram dealers will replace both front-door impact pressure sensors, securing them with the correct rivets. There will be no charge for this service.

The recall is expected to begin Jan. 3, 2018. Ram ProMaster owners can reach FCA customer service at (800) 853-1403. FCA’s number for this recall is T64.
