# Service campaign N252541251

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 listed above may have a condition in which drivers may not be notified of a rear turn\-signal lamp failure. GM will update software calibrations in the vehicle’s exterior lighting control module. For vehicles that are capable of receiving software changes using wireless over\-the\-air \(OTA\) technology, owners who have accepted applicable terms and conditions will have the opportunity to accept these software changes via OTA without having to bring their vehicle to a dealership. Alternatively, all owners may have the updates performed at a GM dealer.
