- [SSM 54366](/bulletins/11025611.md), 2025-11-19, Service bulletin: POWER TRAIN; ELECTRICAL SYSTEM. Some 2015\-2021 Ford and Lincoln vehicles may exhibit an illuminated MIL with diagnostic trouble codes \(DTCs\) P0011, P0012, P0014, P0015, P0016, P0017, P0018, P0019, P0021, P0022, P0024 and/or P0025. Pinpoint test HK in the Powertrain Control and Emissions Diagnosis \(PC/ED\) or in Section 303\-14 of the Workshop Manual \(WSM\) has been updated to address this concern.
- [SSM 52335](/bulletins/10251952.md), 2024-03-20, 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 52314](/bulletins/10251934.md), 2024-03-20, Service bulletin: POWER TRAIN. During service and repair requiring removal and replacement of a crankshaft bolt and/or crankshaft damper, achieving proper torque of the crankshaft pulley bolt is critical. Incorrect torque may allow the bolt to loosen resulting in the timing gear breaking and engine damage. Replacement of the bolt is critical to the repair and accurately following the installation procedure in the Workshop Manual \(WSM\) Section, 303\-01 is extremely important. The bolt torque procedure can be found in the crankshaft front seal removal and installation procedure or in the engine assembly procedure.

- [20B27 S1](/bulletins/10219034.md), 2022-09-01, Service bulletin: POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE \(TCM/PCM/TECM\); POWER TRAIN; POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE:SOFTWARE. Certain 2015\-2019 MKC and 2016\-2019 Explorer vehicles equipped with the 2.3L engine and 6F35 transmission; Powertrain Control Module reprogram. Supplement: Program terms will be in effect through August 31, 2023 This program is now eligible for mobile repairs
- [TSB 22\-2287](/bulletins/10216459.md), 2022-07-28, Service bulletin: POWER TRAIN. Some 2015\-2019 MKC and 2016\-2019 Explorer vehicles equipped with a 2.3L engine may exhibit a vibration/rough idle when the vehicle is in drive \(D\) or reverse \(R\). The vehicle may also exhibit a lack of engine revolutions per minute \(RPM\), lack of acceleration on take off and/or shudder while driving. This may be due to the torque converter overheating causing damage to the torque converter as well as possible internal damage to the transmission. To correct this condition, follow the Service Procedure to replace the torque converter and specified internal transmission components that may have been damaged.
- [SSM 50861](/bulletins/10214492.md), 2022-06-29, Service bulletin: POWER TRAIN. Some 2015\-2016 vehicles equipped with 6F50/6F55 transmission and built on 2\-Nov\-2015 and through 1\-Feb\-2016 may exhibit no reverse, 3rd and 5th gear with diagnostic trouble codes \(DTCs\) P0715,P0717,P0756 and/or P2701. This may be caused by the direct clutch cylinder/tone wheel \(7F283\) inadvertently forcing the snap ring out of position resulting in damage to the direct clutch hub \(7G384\). Service part \(7J250\) complete rotating 3\-5\-R clutch module is now available. Refer to Workshop Manual \(WSM\), Section 307\-01. For claiming, use causal part 7F283 and applicable labor operations in Section 7 of the Service Labor Time Standards \(SLTS\) manual.
- [TSB 22\-2229](/bulletins/10214126.md), 2022-06-13, Service bulletin: ENGINE AND ENGINE COOLING. Some 2015\-2018 Edge and 2017\-2019 Fusion/MKZ/Escape/MKC vehicles equipped with a 2.0L EcoBoost engine may exhibit a low coolant level, white exhaust smoke and/or a runs rough condition with or without an illuminated malfunction indicator lamp \(MIL\). Diagnostic trouble codes \(DTCs\) may include P0300, P0301\-P0304, P0316, P0217, P1285 and/or P1299 stored in powertrain control module \(PCM\). This may be due to coolant intrusion into the cylinder. To correct the condition, follow the Service Procedure to replace the long block engine assembly.
