SSM 545932026-02-27. Service bulletin. ENGINE; POWER TRAIN; FUEL/PROPULSION SYSTEM. Some 2024-2025 F-150, Expedition/Navigator, Escape/Corsair, Bronco, Explorer, Mustang, Maverick vehicles equipped with a 1.5/2.0/2.3/3.5L EcoBoost engine and built on 01-Oct-2024 and through 31-May-2025 may exhibit an extended crank condition, strong fuel smell in the engine oil, high engine oil level and/or may have various drivability diagnostic trouble codes (DTCs) stored in the powertrain control module (PCM) with an illuminated malfunction indicator lamp (MIL). This may be due to an internal fuel leak of the high-pressure fuel pump causing fuel to enter the crankcase and reduce fuel pressure in the direct injection fuel rail. Diagnose this condition using Pinpoint Test HP located in Workshop Manual (WSM), Section 303-04. If no DTCs are stored in the PCM, proceed from Step HP1 to Step HP5 and continue testing. Repair as necessary outside of this article. For claiming, if high-pressure fuel pump replacement is required, use causal part number 9D376 and labor operation code 9543A. If the root cause is identified as anything other than the fuel injection pump, claim the repair outside of this article.

Some 2025 Bronco Sport/Transit vehicles equipped with R-134a refrigerant systems may exhibit a concern of the air conditioning (A/C) blowing warm with a leak detected at the low side service port. This may be due to a concern with the low side service port cap clearance causing the service port valve to open slightly when the cap is fully seated. To correct the condition, discard the old service port cap and service port valve. Install a new service port valve, recharge the system, and install a new low side service port cap using part number DS7Z-19D702-B.
