The recall includes 2013- to 2016-model year Ram 1500 and 2500 trucks and 2014- to 2016-MY Ram 3500 trucks. During these rough driving conditions, the roll rate sensor may trigger a fault within the occupant restraint controller (ORC). If this fault occurs, the rollover side curtain air bag and the seat belt pretensioner will be disabled from deploying, NHTSA said. Dealers will update the ORC software, free of charge, to resolve the problem. The recall is expected to begin June 23.
