A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

SSM 51687	2023-06-16. Service bulletin. TSB 22-2428 is missing some labor operations. For any missing labor operations, claim available new model labor operations or m-time. Refer to this article on the repair order. When replacing the CDF cylinder, the current TSB does not require a complete transmission overhaul or cooler and converter flushing. Ford is currently reviewing the TSB. Monitor OASIS for updates.
SSM 51464	2023-04-05. Service bulletin. Some 2018-2019 Navigators that require a 10 inch center display screen replacement may fail to power up. This may be due to accessory protocol interface module (APIM) software incompatibility with the new center display screen. To correct the condition, run the SYNC Module (APIM) Software Update using the latest software level of the Ford Diagnosis and Repair System (FDRS). The center display screen part number JL7T-18B955-UG or higher requires newer SYNC software to operate and power on. For claiming, use causal part number 18B955 and applicable labor operations in Section 10 of the Service Labor Time Standards (SLTS) Manual.
SSM 51321	2023-02-02. Service bulletin. Some 2018-2022 Expedition vehicles may exhibit a condition of intermittent headlamp operation while the vehicle is OFF and have diagnostic trouble code (DTC) B1533 stored in the body control module (BCM). This may be due to the internal logic within the headlamp switch. Switch and/or module replacement will not resolve this condition. Headlamp operation is not affected while the vehicle is ON. A new headlamp switch is currently under development to correct this condition. Let the customer know they can continue to drive the vehicle and schedule a follow-up appointment in May 2023, when parts are expected to become available. Follow up with the customer to confirm the appointment once OASIS is updated with the repair information.
SSM 51265	2023-01-06. Service bulletin. 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.
SSM 50982	2022-08-15. Service bulletin. Some 2018-2022 Ford/Lincoln vehicles equipped with a wireless charging pad may exhibit one of the following if the customer is using a Magsafe iPhone (iPhone 12 or 13): slow charging, inoperative, notification that the phone has been mispositioned on the charging pad and/or the phone charging icon in the center screen display is not showing. This may be due to a compatibility issue between the customer's phone and the wireless accessory charging module (WACM) that may make it difficult for Ford and Lincoln vehicles to wirelessly charge these specific phones. The phone can still be charged using the USB cable if the vehicle experiences the above symptoms. If the customer is using a Magsafe iPhone such as an iPhone 12 or 13, verify the wireless charging pad works with a Qi certified phone prior to any part replacements.
