NHTSA's summary

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.

Other bulletins for the same vehicles and component
SSM 552282026-10-12. Service bulletin. Some 2020-2026 Aviator/Explorer/F-150/Bronco/Ranger vehicles equipped with a 2.7L or 3.0L (non-diesel) engine may need the front engine cover removed and reinstalled for various reasons. The Workshop Manual (WSM), Section 303-01 Engine > Removal and Installation > Engine Front Cover service procedure has been updated to include a new essential special service tool (ESST) guide pin alignment tool (303-1790) that is used to align the engine front cover to the engine block, preventing the O-ring seal on the engine oil galley feed tube from getting damaged during installation.
SSM 552172026-10-06. Service bulletin. Some 2020-2024 Explorer/Aviator vehicles equipped with 3.0L EcoBoost/hybrid engine may exhibit blue or black exhaust smoke on startup for the first 5 minutes after an overnight cold soak with no illuminated malfunction indicator lamp (MIL) or powertrain diagnostic trouble codes (DTCs) present. This may be due to engine oil breaching the dynamic oil seals separating the bearing core from the turbine housing in the left side turbocharger assembly. There is a new, updated left side turbocharger oil supply tube equipped with an internal check valve to prevent the engine oil from entering turbine housing after the engine is off. Replace the existing left side turbocharger oil supply tube with the updated service part that includes the check valve (service part# L1MZ-9T516-B) or latest level part. Refer to the Workshop Manual (WSM), Section 303-04 Fuel Charging and Controls - Turbocharger > Removal and Installation > Turbocharger Oil Supply Tube LH. For claiming, use causal part 9T516 and labor operation code 9440AL.
SSM 552112026-10-06. Over-the-air update. 2023-2026 Escape and 2025-2026 Bronco Sport vehicles equipped with a 1.5L EcoBoost engine may require removal of the turbocharger wastegate control actuator linkage for various reasons. The Workshop Manual (WSM), Section 303-04 Fuel Charging and Controls - Turbocharger - 1.5L EcoBoost > Removal and Installation > Wastegate Control Actuator Linkage service procedure has been added. In addition, the wastegate control actuator linkage rod with retaining clips (6K682) and actuator linkage rubber boot seal (9E416) have been released as lower-level components to complete the repair without replacing the entire turbocharger wastegate control actuator assembly.
SSM 551572026-09-15. Service bulletin. Some 2022-2024 Maverick Hybrid vehicles may exhibit an intermittent vibration and/or crunching noise after a cold start while the engine is running with the vehicle stationary in drive with no throttle input and brakes applied. An intermittent engine rocking or rolling motion in one direction may also be observed while the concern is present with the hood open.<br /><br /> The noise may be present with no drivability concerns, relevant diagnostic trouble codes (DTC) stored, warning indicators illuminated and/or warning messages displayed. The noise may reduce or be eliminated after several minutes of driving when the powertrain warms up.<br /><br /> This condition does not affect vehicle durability and no additional diagnosis or service is required for this condition at this time. Inform customers that they can continue to drive the vehicle and engineering is currently working on a solution for this condition that is expected in Q4 of 2026. Replacement of the engine or transmission will not resolve this condition. Monitor Professional Technician System (PTS) for additional information and schedule s
SSM 551422026-09-04. Service bulletin. Some 2023-2025 Escape vehicles built on or before 16-Sep-2024 equipped with 1.5L EcoBoost engine may exhibit an "Engine Coolant Over-Temperature" warning message displayed in the IPC and an illuminated MIL with DTCs P1285 and/or P1299 stored in the powertrain control module (PCM) during hard acceleration or under high load conditions. This may be due to machining chips trapped in the cylinder head causing a potential blockage in the coolant passage near the cylinder head temperature 2 (CHT2) port. To diagnose this condition, start the vehicle and idle for 15 minutes. Perform a road test at a temperature above -20°C (-4°F) and apply wide-open throttle (WOT) hard accelerations in rapid succession. If the concern cannot be replicated, drain and refill the coolant system. If the concern can be replicated, drain the coolant system. Perform the Engine Cooling System Flushing procedure in Workshop Manual (WSM) > 303-03A Engine Cooling - 1.5L EcoBoost > General Procedures. Do not use the VC1 flush additive. Reassemble the engine. Fill and bleed the coolant system and re-evaluate the concern. If the concern pers
