Official 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.
What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
