Rear seat entertainment systems are not on a controller area network (CAN) and are not supported by the Ford Diagnostic and Repair System (FDRS). Certain system concerns may be resolved through software updates which will automatically download once each individual monitor is connected to Wi-Fi. Diagnostic support for rear seat entertainment systems is provided by VOXX electronics. If necessary, contact the VOXX Customer Service Department at 1-866-869-7888. If possible, record the device serial number by selecting the gear/Setup icon > Settings > Device and Software > About. If the unit will not power up, the serial number is on a label on the back of the monitor. It is helpful to know the date the issue occurred, how long the monitors were on prior to the issue, what app/input/media was being used, and if the system software was recently updated prior to the concern starting. For claiming, refer to the Warranty and Policy manual for

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 523142024-03-20. 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.

Vehicle may also have diagnostic trouble code (DTC) P07E6 and/or P07E4 stored in the powertrain control module (PCM) or transmission control module (TCM) and/or a possible audible noise. This may be due to a leak in the park valve circuit. To correct the condition, follow the Service Procedure to inspect the park system hardware for wear or damage and replace the valve body separator plate with an improved valve body separator plate.
SAN Vol1 Issue22023-11-02. Service bulletin. UNKNOWN OR OTHER; EQUIPMENT:OTHER:OWNERS/SERVICE/OTHER MANUAL. The Service Awareness Newsletter is an informal communication that contains information that may not be presently available in a TSB, SSM, or GSB, or other electronic communication. This article includes information on warranty, technical service tips and other service information
SSM 519392023-10-06. Service bulletin. POWER TRAIN. Some 2017-2023 Ford and Lincoln vehicles equipped with a 10R60/10R80/10R80 MHT/10R100 transmission may exhibit a whine noise at idle and/or while driving. This may be identified as coming from the bellhousing and the front of the transmission fluid pan. The whine noise may become louder when the transmission is at operating temperature and may increase with engine revolutions per minute (RPM) in the park (P) position. A small amount of whine noise is considered to be characteristic of the 10R60/10R80/10R80 MHT/10R100 transmissions due to the offset gear drivetrain in the front support and has no effect on durability. Use the Report a Vehicle Concern link at the bottom of OASIS to submit a report if there is a customer concern of whine noise describing operating conditions and noise severity.
