- [SSM 55098](/bulletins/11036338.md), 2026-08-25, Service bulletin: UNKNOWN OR OTHER; POWER TRAIN; ENGINE. Some 2013\-2016 Super Duty vehicles equipped with a 6.7L diesel engine and 2015\-2019 Transit vehicles equipped with a 3.2L diesel engine may not pass a state smog test due to the exhaust gas system \(EGS\) monitor that will not run after completing the exhaust gas sensor drive cycle located within Section 2 of the Powertrain Control/Emissions Diagnostics \(PC/ED\) Manual \> Drive Cycles. This may be due to the vehicles diesel oxidation catalyst \(DOC\) age counter being under the 120\-minute age requirement. There is an all\-new "PCM Catalytic Converter Age Evaluation" application within the latest version of the Ford Diagnosis and Repair System \(FDRS\). Use this new FDRS application to determine the age \(in minutes\) of the DOC. If the age is less than 120 minutes, perform manual regenerations to increase the catalyst age counter to satisfy the monitor age requirement. If further assistance is needed, contact the technical assistance center \(TAC\). Note: this article only applies to the EGS monitor. Problems with other vehicle monitors not running successfully must be addressed using normal diagnostics located i
- [SSM 54690](/bulletins/11030810.md), 2026-04-06, Service bulletin: ENGINE. Some 2013\-2016 Super Duty vehicles equipped with a 6.7L diesel engine and 2015\-2019 Transit vehicles equipped with a 3.2L diesel engine may not pass a state smog test due to the exhaust gas system \(EGS\) monitor that will not run after completing the Exhaust Gas Sensor drive cycle located within Section 2 of the Powertrain Control/Emissions Diagnostics \(PC/ED\) Manual \> Drive Cycles. This may be due to the vehicles diesel oxidation catalyst \(DOC\) age counter being under the 120\-minute requirement. Engineering is investigating this issue and working on a solution.
- [SSM 52476](/bulletins/10254138.md), 2024-05-03, Service bulletin: EQUIPMENT. All accessory stick\-on keyless entry keypads come with a wallet card containing the master code. If the accessory keypad was factory installed, this card will be placed in the glove box and should be handed to the vehicles owner during initial delivery. Unlike the integrated \(wired\) factory keypad, the accessory keypad master code cannot be retrieved from the vehicle using a diagnostic scan tool. If the wallet card for an accessory keypad is lost, follow these steps to recover the code. Dealer Key Code access is granted through the Dealer Program Enrollment System \(DPES\); dealership management can authorize users. The authorized user must go to FMCDealer.com \> Parts and Service \> Parts Product Line Information \> Keys/Entry Devices \> Aftermarket Keyless Entry Keypad Code Access. Follow the instructions on the screen to obtain the master code for the accessory keypad.
- [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.

Some vehicles equipped with power folding mirrors may exhibit power folding mirrors that are inoperative or exhibit a clicking sound. This may be due to the mirrors being manually folded in, during transportation, going through a car wash, bumped in a parking lot, or found during pre\-delivery inspection \(PDI\). Prior to the replacement of any components, attempt to synchronize the mirrors by following the Power Mirrors Synchronization procedure. Refer to Workshop Manual \(WSM\) Section 501\-09 Rear View Mirrors \- General Procedures \- Power Mirrors Synchronization.
