Service bulletins for the 2021 Ford F-150

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

Customers may describe fog lamps blinking, turning on or off, or flashing. If the vehicle is equipped with cornering lamps, this may be normal function. Under certain conditions and inputs, either lamp might turn on or off independently to aid visibility during cornering. This condition does not affect vehicle durability and no additional diagnosis or service is required for this condition at this time. For additional cornering lamp information, refer to the Owner's Manual and/or Workshop Manual (WSM), Section 417-01.

TSB 25-22732025-06-24. Service bulletin. ELECTRICAL SYSTEM; UNKNOWN OR OTHER. This article supersedes TSB 24-2443 to update the vehicles affected. Some of the vehicles listed in the Model statement above equipped with the 400-watt direct current/alternating current (DC/AC) inverter system (minor feature code HUKAJ) with a pickup bed alternating current (AC) power outlet socket may exhibit inoperative power outlets with diagnostic trouble code (DTC) B1330:9A stored in the body control module (BCM). This may be due to a connection issue at C4628. NOTE: This article does not apply to vehicles with an inverter system other than the 400-watt DC/AC inverter system with a pickup bed AC power outlet socket.
SSM 539662025-06-24. Service bulletin. ELECTRICAL SYSTEM; UNKNOWN OR OTHER. Some 2021-2025 Ford/ Lincoln vehicles equipped with SYNC4 may not be able to perform an update to the accessory protocol interface module (APIM). This may be due to the software in the APIM. Ford Engineering has de-activated the ability to update these SYNC4 APIM modules as applicable, and the Ford Diagnosis and Repair System (FDRS) will not present an update for the APIM module. Some existing directed repairs may be impacted, check Professional Technician System (PTS) before attempting any specific technical service bulletin (TSB)/special service message (SSM) and check field service action (FSA) landing pages before attempting any FSA repairs. For any vehicle repairs requiring a software update that includes an APIM update in the programming sequence, if the 5-digit product code for the APIM software is equal to or lower than 23187, do not attempt to update affected modules at this time. To determine the 5-digit product code for the APIM software on the vehicle, while the vehicle center display screen is powered up with ignition in run or accessory, go to Settings > General > About SYNC.
SSM 538782025-06-11. Service bulletin. POWER TRAIN. Some 2021-2025 Expedition/Navigator and 2021-2025 F-150 non-Lightning/non-PowerBoost vehicles may exhibit a rattle/scraping noise from the bellhousing area on start-up. This may be due to the torque converter studs contacting the engine to transmission spacer plate (separator plate). To correct this condition, inspect the engine to transmission spacer plate and torque converter studs for wear/damage. If wear/damage is found, replacement of the torque converter is not necessary. Replace only the engine to transmission spacer plate. Refer to Workshop Manual (WSM) Section 303-01 > Engine to Transmission Spacer Plate for full spacer plate removal and installation. When reinstalling the starter motor, make sure the starter is flush with the engine to transmission spacer plate prior to tightening the studbolts. Failure to do so may result in damaging the newly installed engine to transmission spacer plate.
