Service bulletin SA-016-25
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
The new AWD rear differential DOES NOT come with a breather cap on the rear of the differential, therefore a new one will need to be ordered and installed when replacing the differential. NOTE: The breather threads have a sealant and locking compound that prevents it from being reused. Refer to GEPC for the correct part number of the Differential Breather. The instructions on MGSS will be updated soon to include replacing the breather when replacing the differential with a new unit.

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