Service bulletin 24H01

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.

TSB 26-22102026-06-05. Service bulletin. Some of the vehicles listed in the Model statement above may exhibit all of the following conditions: * Engine misfire condition * Illuminated malfunction indicator lamp (MIL) with diagnostic trouble codes (DTC) P0301, P0302, P0303, and/or P0304 stored in the powertrain control module (PCM)
SSM 545932026-02-27. Service bulletin. Some 2024-2025 F-150, Expedition/Navigator, Escape/Corsair, Bronco, Explorer, Mustang, Maverick vehicles equipped with a 1.5/2.0/2.3/3.5L EcoBoost engine and built on 01-Oct-2024 and through 31-May-2025 may exhibit an extended crank condition, strong fuel smell in the engine oil, high engine oil level and/or may have various drivability diagnostic trouble codes (DTCs) stored in the powertrain control module (PCM) with an illuminated malfunction indicator lamp (MIL). This may be due to an internal fuel leak of the high-pressure fuel pump causing fuel to enter the crankcase and reduce fuel pressure in the direct injection fuel rail. Diagnose this condition using Pinpoint Test HP located in Workshop Manual (WSM), Section 303-04. If no DTCs are stored in the PCM, proceed from Step HP1 to Step HP5 and continue testing. Repair as necessary outside of this article. For claiming, if high-pressure fuel pump replacement is required, use causal part number 9D376 and labor operation code 9543A. If the root cause is identified as anything other than the fuel injection pump, claim the repair outside of this article.

SSM 539742025-07-02. Service bulletin. Some 2024-2025 Mustang vehicles equipped with a 2.3L EcoBoost engine may require removal of the air conditioning compressor belt due to various concerns. Workshop Manual (WSM), Section 303-05 has been updated with improved removal and installation service procedure steps.
SSM 539712025-07-02. Service bulletin. Some 2023-2025 Escape vehicles equipped with a 1.5L/2.0L EcoBoost engine, 2023-2025 Corsair vehicles equipped with a 2.0L EcoBoost engine, 2024-2025 Nautilus vehicles equipped with a 2.0L EcoBoost engine, 2024-2025 Mustang vehicles with a 2.3L EcoBoost engine, and 2025 Bronco/Explorer/Ranger vehicles equipped with a 2.3L EcoBoost engine may exhibit an engine misfire condition with diagnostic trouble codes (DTC) P0301, P0302, P0303 and/or P0304 set in the powertrain control module (PCM). This may be due to the spark plugs and/or ignition coils. To correct the condition, refer to Workshop Manual (WSM), Section 303-07 for normal diagnostics.
SSM 537642025-05-21. Service bulletin. Some 2020 Continental, 2020-2024 Edge/Nautilus, 2020-2025 Explorer/Aviator/Escape/Corsair/F-150/F-Super Duty/Ranger/Transit/E-Series, 2021-2025 Bronco, and 2022-2025 Maverick vehicles may require an engine cooling system flush to be performed for various concerns. Workshop Manual (WSM), Section 303-03 has been updated to eliminate the need to remove and install the radiator assembly to perform a radiator flush.
SSM 526302024-07-03. Service bulletin. Some 2023-2024 Escape/Corsair vehicles equipped with a 1.5L or 2.0L EcoBoost engine, 2024 Mustang vehicles equipped with a 2.3L EcoBoost engine, and 2024 Nautilus vehicles may exhibit an engine misfire condition with diagnostic trouble codes (DTC) P0301, P0302, P0303 and/or P0304 set in the powertrain control module (PCM). If the codes are stored in the PCM, remove and inspect the condition of all the spark plugs. If all spark plugs are found to be free of damage, replacement of the spark plugs is not necessary. Refer to the Workshop Manual and perform normal diagnostics. If any spark plugs appear to be damaged, use a borescope to inspect the condition of the cylinder walls. If the cylinder walls are scored/scraped/damaged, replace the long block engine assembly (6006) to resolve this condition. If the cylinder walls are not scored/scraped/damaged, replace the damaged spark plug(s) and advise the customer that engineering is investigating this issue. Monitor OASIS for additional information and schedule service appointments for customers once the repair becomes available.
SSM 524402024-04-29. Service bulletin. Some 2024 Mustang GT vehicles built on 15-Nov-2023 and through 26-Mar-2024 may exhibit an inoperative auto start-stop feature. This may be due to the body control module (BCM) configuration. Engineering is currently working on a solution for this condition that is expected June 2024. Replacement or reprogramming of the BCM will not resolve this condition. Monitor OASIS for additional information and schedule service appointments for customers once the repair becomes available. Vehicles built on or before 14-Nov-2023 are not equipped with auto start-stop and the Workshop Manual (WSM) is in the process of being updated with this information.
SSM 523352024-03-20. Service bulletin. For 2015-2024 Ford and Lincoln vehicles equipped with turbocharged engines and customer concern of an engine oil leak, refer to Workshop Manual (WSM), Section 303-00 for oil leak inspection and testing methods. Ford has evaluated turbochargers replaced for oil leak symptoms and although oil may collect on the external surface of a turbocharger, it is extremely rare for a turbocharger assembly to be the root cause of the oil leak. Careful inspection of the turbocharger oil feed and drain tubes should be performed along with the recommended WSM procedures as needed. Warranty claims for turbocharger replacement going forward will be assessed.
