Service bulletin SSM 46525

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.

NHTSA's summary

Some 2017 Escape and MKC vehicles equipped with a 1.5L, 2.0L or 2.3L engine may exhibit an illuminated MIL with diagnostic trouble codes (DTCs) P0455, P0456, P144C and/or P1450 stored in the powertrain control module (PCM) memory. Vehicles may also exhibit a rough idle and/or slow fuel fill concern. If normal diagnosis leads to the replacement of the canister purge valve then inspect for the presence of liquid fuel in the vapor lines at the EVAP canister purge valve and the EVAP canister. Liquid fuel should not be present in the EVAP canister purge valve, EVAP canister or any of the vapor lines. Engineering is investigating this concern. Monitor OASIS for updates.

SSM 52335	2024-03-20. 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.
SSM 51409	2023-04-04. Service bulletin. Some 2014-2020 Fusion and 2017-2019 Escape vehicles may be equipped with a 1.5L Ecoboost engine that uses a 50-tooth variable camshaft timing (VCT) intake and exhaust unit from the assembly plant or if a service long block was installed. VCT locking tool 303-1097 is not compatible with this system. If VCT system service is required, replace both the intake VCT (service part DS7Z-6256-F) and exhaust VCT (service part DS7Z-6256-G) as a pair. An interim loaner tool program has been established to enable these repairs. Contact 1-800-403-4844 (Monday-Friday 8:00am to 8:00pm EST; Saturday 8:00am to 3:00pm EST) to obtain this tool. A VCT locking tool compatible with the 50-tooth system is under development and will be sent to dealerships. Continue to monitor OASIS for additional information.
