SSM 523352024-03-20. Service bulletin. 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.

21N012021-09-05. Service bulletin. This program provides a no-cost, one-time repair (if needed) to the high-speed cooling fan relay and respective electrical terminals, if affected, to ten (10) years of service or 150,000 miles from the warranty start date of the vehicle, whichever occurs first.
21B052021-09-05. Service bulletin. After extended idling, the high-speed cooling fan relay may fail in some of the affected vehicles. A failure will cause the fan to either continuously run or never turn on. A continuously running fan will increase the temperature of the relay’s connections (terminals) to beyond their design maximum. This may eventually create an electrical arc which heats and damages the relay terminals. Customers may experience a drained battery and a non-functional or even a melted/burned high-speed cooling fan relay inside the battery junction box (BJB). A damaged non-functional relay causing the fan to never turn on, may lead to engine overheating at idle.
