# Service bulletin SSM 54386 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. - Type: Service bulletin - NHTSA id: 11025808 - Published by NHTSA: 2025\-12\-01 - Manufacturer's number: SSM 54386 - Manufacturer's date: 2025\-11\-18 - NHTSA component: UNKNOWN OR OTHER; ENGINE ## NHTSA's summary For 2021\-2025 Corsair vehicles, if diagnostics lead to the heating ventilation air conditioning \(HVAC\) air registers as the causal part, a new lower level part is available. It is no longer necessary to replace the air registers if only the HVAC air register arm or linkage are damaged.\

Some of the vehicles listed in the Model statement above may exhibit all of the following conditions: \* Engine misfire condition \* Illuminated malfunction indicator lamp \(MIL\) with diagnostic trouble codes \(DTC\) P0301, P0302, P0303, and/or P0304 stored in the powertrain control module \(PCM\) - [SSM 54593](/bulletins/11029082.md), 2026-02-27, 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. - [25H03](/bulletins/11023856.md), 2025-10-03, Other: UNKNOWN OR OTHER; ENGINE.

Some 2023\-2026 Corsair vehicles may exhibit a concern when changing the fan speed, the fan speed display icon \(OFF/AUTO/fan speed number\) changes to a different language character or symbol. This may be due to the accessory protocol interface module \(APIM\) software. Replacement or reprogramming of the APIM will not resolve this condition. Inform customers that engineering is currently working on a solution for this condition and will be released via software updates delivered over\-the\-air \(OTA\) expected Q4 2025. Software will update automatically if vehicle connectivity is enabled in the vehicles settings. Schedule a service visit for customers who have disabled vehicle connectivity or who report that they did not receive the update by October 2025. Monitor Professional Technician System \(PTS\) for additional information. - [25H03](/bulletins/11022299.md), 2025-09-02, Other: ELECTRICAL SYSTEM; ENGINE.
