Service bulletin SSM 52735
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 2024 Expedition/Navigator vehicles built on or before 07-Mar-2024 may exhibit a concern where the vehicle is unable to complete the trailer calibration drive for the trailer backup assistance feature. The customer will see all instructional information in the center display screen for the trailer calibration including "Drive Straight Forward To Calibrate", "Drive Left Or Right To Calibrate" and "System Calibrating", but the system will never complete the calibration process. This will prevent customers from using the feature to back up a trailer. This may be due to the software in the image processing module A (IPMA).

Listing a model year does not mean every vehicle of it is concerned: the document says which.
