Service bulletin SSM 53643
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 2025 Expedition/Navigator vehicles may exhibit diagnostic trouble codes (DTCs) B144F:19, B144F:13, B1557:19, B1557:31 and/or B15E8:19 in the rear gate trunk module (RGTM) when a diagnostic self-test is performed. If no other symptoms, DTCs, or issues are identified, no further action is required. Replacement and/or reprogramming of the RGTM will not resolve this condition.
