Service bulletin WB15-53A
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
On the vehicles covered by this bulletin, two DPF (diesel particulate filter) plugs may be loose. If a plug is loose, it may fall out under the effect of vibration. This may cause leakage of hot exhaust gases. It is therefore necessary to check if the plugs are tight and to tighten them properly if applicable.
The document

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