21M05-S12022-07-28. Service bulletin. STRUCTURE:BODY:TAILGATE; LATCHES/LOCKS/LINKAGES; EQUIPMENT. Certain 2017-2022 Model Year Super Duty Vehicles Equipped with a Power Release Tailgate - Unintended Tailgate Opening. In the affected vehicles, some customers report experiencing an unintended tailgate opening and may have previously serviced their vehicle for this concern.

SSM 508302022-06-17. Service bulletin. ENGINE AND ENGINE COOLING; EQUIPMENT ADAPTIVE/MOBILITY. Some 2020-2022 F-Super Duty vehicles equipped with a 7.3L engine and built on or before 11-May-2022 may exhibit a ticking/clicking/tapping noise at idle that is loudest at the front of the engine where the front timing cover meets the oil pan. This may be due to a cracked oil pump drive gear. If the noise originates from the lower front of the engine, remove the accessory drive belt and retest. If the noise is still present, remove the oil pan and rotate the crankshaft 360 degrees to inspect for cracking. If cracked, replace the oil pump drive gear (LC3Z-6306-A).
21P19-S12022-06-10. Service bulletin. EQUIPMENT:ELECTRICAL. Certain 2020-2021 Model Year Super Duty Vehicles - Reconfigure the RCM with As-Built Data. In all of the affected vehicles, the event data recorder (EDR) was inadvertently disabled. In the event of a crash or near crash-like situation, the event data recorder within the restraint control module (RCM) will not collect and store data used to help understand how the safety systems performed. There is no impact to normal vehicle operation or the vehicle’s safety systems.
SSM 507422022-05-14. Service bulletin. POWER TRAIN; ELECTRICAL SYSTEM. Some 2020-2022 F-Super Duty vehicles may exhibit an illuminated malfunction indicator lamp (MIL) with diagnostic trouble code (DTC) P0073 for the ambient air temperature sensor stored in the powertrain control (PCM). When performing pinpoint test BF in Workshop Manual (WSM), Section 413-01, the ambient air temperature sensor/outside air temperature display reset procedure has been added to the Ford Diagnostic Repair System (FDRS) diagnostic scan tool. Depending on how the vehicle is equipped, run the FCIM or HVAC. Reset the Outside Air Temperature Sensor Learned Values application. Clear DTCs and retest after performing the reset procedure.
CSR 5182021-07-09. Service bulletin. WHEELS. Ford Motor Company has determined a defect that relates to motor vehicle safety exists on certain 2021 model year Super Duty vehicles with front-wheel hub extensions built between February 7, 2021, and June 3, 2021. Contact your local Ford dealer to schedule a service date to perform the recall. Refer to the included communication from Ford for additional information. Altec is not able to complete this repair.

21B03-S42021-07-01. Service bulletin. POWER TRAIN. In all of the affected vehicles, a distressed No. 1 planetary needle bearing inside the ring gear assembly will generate contamination that may produce rough shifts. A wrench light is likely to come on, and the transmission may go into safe mode and only operate in seventh gear. As damage progresses, the transmission may only be capable of limited vehicle speed or may not engage in forward or reverse.
SSM 497852021-06-01. Service bulletin. FUEL SYSTEM, DIESEL:STORAGE:TANK ASSEMBLY; FUEL SYSTEM, GASOLINE:STORAGE:TANK ASSEMBLY:FILLER PIPE AND CAP. Some 2021 F-Super Duty and 2021-2022 E-Series vehicles equipped with a 6.2L or 7.3L gasoline engine may exhibit an illuminated malfunction indicator lamp (MIL) with diagnostic trouble code (DTC) P0457 stored in the powertrain control module (PCM). This may be due to a loose fuel filler cap. The fuel filler cap design has changed, requiring multiple turns to seal properly. Advise the customer to turn the fuel filler cap clockwise until there is at least one audible click to seal properly. For further diagnostics, refer to the Powertrain Control/Emissions Diagnosis (PC/ED) manual, pinpoint test HX.
SSM 497782021-06-01. Service bulletin. FUEL SYSTEM, DIESEL:STORAGE:TANK ASSEMBLY; FUEL SYSTEM, GASOLINE:STORAGE:TANK ASSEMBLY:FILLER PIPE AND CAP.

This may be due to a loose fuel filler cap. The fuel filler cap design changed for 2021 to require three full turns to properly tighten. Advise the customer of the design change. For further diagnostics, refer to the Powertrain Control/Emissions Diagnosis (PC/ED) manual, pinpoint test HX.
SSM 494392021-02-04. Service bulletin. POWER TRAIN; EQUIPMENT; EQUIPMENT ADAPTIVE/MOBILITY. Some 2020-2021 F-Super Duty vehicles with 6.7L and 10R140 powertrain may exhibit an illuminated powertrain malfunction indicator (wrench) lamp with only DTC P07F6 stored in the transmission control module (TCM). The vehicle may also exhibit harsh engagements, poor shift quality and/or loss of 9th gear as a result of the DTC being set. If no additional DTCs or symptoms are present, clear keep alive memory and transmission adaptive tables with the appropriate Ford diagnostic scan tool, and perform an adaptive learning drive cycle. Transmission replacement is not necessary. Inform customers that a further improved calibration will be available in early March 2021. Let the customer know they can continue to drive the vehicle after performing this SSM, and schedule a service appointment for early March 2021. Monitor OASIS for updates.
