SSM 523352024-03-20. Service bulletin. ENGINE AND ENGINE COOLING. 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.
SSM 522012024-01-30. Service bulletin. ELECTRICAL SYSTEM; ENGINE AND ENGINE COOLING. Some 2020-2023 Escape, 2021-2023 Corsair vehicles equipped with 2.5L engine full hybrid electric vehicle (FHEV) and plug-in hybrid electric vehicle (PHEV) powertrain and 2022-2023 Maverick vehicles equipped with 2.5L engine FHEV powertrain may exhibit a condition where the 12V battery voltage is low or discharged with diagnostic trouble code (DTC) U3003:62 stored in the direct current/direct current (DC/DC) converter control module. The vehicle may also exhibit DTC U3003:16 and/or U3000:04 stored in the DC/DC converter control module. This may be due to an open in the 300 amp high-current fuse F4 located in the high-current battery junction box (BJB). To correct this condition, refer to Workshop Manual (WSM), Section 414-05 > Pinpoint Test H to verify the 300 amp high-current fuse condition. If the high-current fuse is found to be open, replace the high-current fuse per the application listing in the parts catalog. Recharge and test the 12v battery. For repairs under warranty, use the base part number of the component that caused the damage to the fuse.

The vehicle may also exhibit an inoperative remote start feature and/or lock and unlock functionality. This may be due to the software in the telematics control unit (TCU). To correct this condition, follow the Service Procedure to reprogram the TCU.
SSM 504852022-02-16. Service bulletin. ELECTRICAL SYSTEM; ENGINE AND ENGINE COOLING. Some 2019-2022 Edge/Nautilus, 2020-2022 Escape/Corsair, and 2021-2022 Bronco Sport vehicles equipped with a 2.0L EcoBoost or 2.3L EcoBoost may exhibit a lack of power with an illuminated malfunction indicator lamp (MIL) with diagnostic trouble codes (DTC) P02AB, P0243, P0299, P25B3, P25B4, P2AB7, P2AB8 and/or P2AB9. This may be due to an inoperative wastegate actuator, missing wastegate actuator e-clip or non-visible damage to the actuator rod. If the diagnostic procedures lead to replacement of the turbocharger assembly, note that a lower level service component has been released K2GZ-9G488-B for Edge/Nautilus/Escape/Corsair/Bronco Sport for service to replace the actuator, actuator rod and both e-clips instead of a complete turbocharger assembly. When replacing the wastegate actuator, it is required to replace all parts included in the service kit.
SSM 503252021-12-26. Service bulletin. EQUIPMENT; ENGINE AND ENGINE COOLING; EQUIPMENT ADAPTIVE/MOBILITY. Some 2021 Escape/Corsair 2.5L PHEV vehicles may exhibit an illuminated MIL with DTCs P2183 and/or P26C1 present. The vehicle may also exhibit an engine overheat message in the instrument panel cluster. Engineering is aware of this concern and is working on a solution. Continue with checking the engine coolant level, inspect the cabin heater coolant temperature sensor (ECT sensor 2) connector for contamination and perform Workshop Manual (WSM), Section 412-00 pinpoint test AQ. If no concern is found and the vehicle does not exhibit DTC P1285 or P1299, clear the DTCs. If DTCs P1285 or P1299 are present, perform normal WSM diagnosis and repair. Inform customers that Ford is working on a resolution and that the vehicle is safe to drive. Monitor OASIS for updates. Once the solution becomes available, contact the customer and set up a service appointment.

Some 2019-2021 Edge/Nautilus/Ranger, 2020-2021 Escape/Corsair/Explorer, and 2021 Bronco Sport vehicles equipped with a 2.0L/2.3L EcoBoost may exhibit a lack of power with an illuminated malfunction indicator lamp (MIL) with diagnostic trouble codes (DTC) P02AB, P0243, P0299, P1464, P25B3, P25B4, P2AB7, P2AB8 and/or P2AB9. This may be due to an inoperative wastegate actuator, missing wastegate actuator e-clip or non-visible damage to the actuator rod. A lower level service component has been released, K2GZ-9G488-B for Edge/Nautilus/Escape/Corsair/Bronco Sport vehicles and LB5Z-9G488-B for Explorer/Ranger vehicles, for service to replace the actuator, actuator rod and both e-clips. When replacing the wastegate actuator, it is important to replace all parts in the service kit. Turbocharger replacement is not necessary to correct the condition.
SSM 499242021-08-02. Service bulletin. ENGINE AND ENGINE COOLING; FUEL SYSTEM, GASOLINE:DELIVERY:FUEL PUMP. Some 2019 MKC, 2019-2021 Edge/Nautilus/Escape/Ranger/Explorer, 2020-2021 Corsair, and 2021 Bronco Sport vehicles equipped with 2.0L and 2.3L EcoBoost engines may exhibit a light to moderate ticking type noise at idle (600-700 RPM). The noise is usually more prominent in the area of the high-pressure fuel pump, located on the top of the engine just behind the number 4 ignition coil. This noise is not detrimental to engine function and has no short or long-term effects on engine durability. This an operating characteristic of these engines and no repairs should be attempted.
