I M P O R T A N T

  • Your vehicle is involved in GM safety recall N192263741.
  • Schedule an appointment with your GM dealer.
  • This service will be performed for you at no charge.

 

Why is your vehicle being recalled?In some of the affected vehicles, the power supply bolt in the relay box may not have been properly tightened during harness production at the supplier.  This may lead to melting of the power wire and/or a loss of electrical power to the vehicle, which can lead to an engine stall.  If the bolt is loose, the vehicle could lose electrical power and stall while being driven, increasing the risk of a crash.
What will we do? Your GM dealer will inspect and torque the power supply bolt in all affected vehicles.  During the inspection, the harness and relay box will be checked for damage and any excess insulation.  If there is any excessive insulation, the bolt will be removed, the excess insulation will be trimmed away, and the bolt will then be torqued to the appropriate specification.  If the harness or relay box is found to be damaged it will be repaired or replaced.  This service will be performed for you at no charge.  Because of service scheduling requirements, it is likely that your dealer will need your vehicle longer than the actual inspection and service correction time of approximately 48 minutes, but additional time may be necessary.
What should you do? You should contact your GM dealer to arrange a service appointment as soon as possible.
Do you have questions?If you have questions or concerns that your dealer is unable to resolve, please contact the appropriate Customer Assistance Center at the number listed below.
