SSM 49573

Some 2021 F-150 vehicles equipped with a 3.5L PowerBoost engine may experience a rough running engine during idle and an illuminated malfunction indicator lamp (MIL) with diagnostics trouble code (DTC) P0300, P0304, P050E and/or P2451 stored in the powertrain control module (PCM). Inform customers that Ford is developing a calibration software update for the PCM that is expected in March. Let the customer know they can continue to drive the vehicle and schedule a follow-up appointment for repair in April. Once the update becomes available, contact the customer and confirm the service appointment is going forward. Monitor OASIS for updates.
