Service campaign N252510321-01
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
We identified an issue within SPS that prevented the correct software to be loaded to these vehicles. As a result, we have re-opened these VINs. Please perform the ECM update again which will allow the remedy software to be installed. Then, submit a new claim with a new warranty claim code. If the claim has not been submitted yet, please perform the ECM update again prior to submitting the claim. Thank You.

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