  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.
