Service campaign N262558300

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

Certain vehicles may have been built with the incorrect Body Control Module (BCM) calibration data file. Dealers will reprogram the BCM with the correct software.

The document

The document is the manufacturer's. This site does not hold it. NHTSA files a document at one of these two addresses; we have not asked NHTSA which.

Vehicles listed
CHEVROLET SILVERADO 15002026 (the catalog's model; the bulletin names a series or trim of it)
GMC SIERRA 15002026 (the catalog's model; the bulletin names a series or trim of it)

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