Service campaign N262547330
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 a condition in which the Telematic Control Module may enter an unrecoverable state. Dealers are to reprogram the Telematic Control Module. Important: The module may be several software versions behind and could take multiple programming events to bring it to the latest software level (The same calibration screen MUST be displayed to validate the module has been programmed to the latest level). Owners who have accepted applicable terms and conditions will have the opportunity to accept these software changes using wireless over-the-air (OTA) technology without having to bring their vehicle to a dealership. Alternatively, owners may have their vehicle serviced at a GM dealer to receive these software updates.
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.
