Dealer Responsibility
All new, used, GM Certified Pre-Owned (CPO), courtesy transportation vehicles, dealer shuttle vehicles, CarBravo, etc.
in dealers' possession and subject to this field action must be held and inspected/repaired per the service procedure of
this bulletin before customers take possession of these vehicles. Involved vehicles must be held and not delivered to
customers, dealer-traded, released to auction, used for demonstration, or any other purpose.
All GM Certified Pre-Owned (CPO) vehicles currently in the dealers’ inventory within the SHIFT Digital system will be
de-certified and must be held and remedied per the service procedure in this bulletin. Upon submitting an accepted/paid
warranty transaction in the Global Warranty Management (GWM) system, the vehicle can be re-certified for sale within
the SHIFT Digital system, or once again be used in the Courtesy Transportation Program.
Dealers are to service all vehicles subject to this program at no charge to customers, regardless of mileage, age of vehicle,
or ownership, through March 31, 2026. Customers who have recently purchased vehicles sold from your vehicle inventory,
and for which there is no customer information indicated on the involved vehicle listing, are to be contacted by the dealer.
Arrangements are to be made to make the required correction according to the instructions contained in this bulletin.
Program follow-up cards should not be used for this purpose, since the customer may not as yet have received the
notification letter.

Customer Satisfaction Program
N242436240 Multiple Module Reprogramming
In summary, whenever a vehicle subject to this program enters your vehicle inventory or is in your facility for service
through March 31, 2026, you must take the steps necessary to be sure the program correction has been made before
selling or releasing the vehicle.
Dealer Reports – For USA & Export
For dealers with involved vehicles, a listing has been prepared and will be available through GM GlobalConnect Maxis
Field Action Reports or sent directly to export dealers. The Inventory tab of the dealer reports will contain VINs that apply
to this field action. This information is intended to assist dealers with the PROMPT COMPLETION of these vehicles. The
Customer In-Service tab will contain customer names and addresses from Motor Vehicle Registration Records. The use
of such motor vehicle registration data for any purpose other than follow-up necessary to complete this field action may
be a violation of law in several states.

GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these technicians of
conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained
technicians have the tools, equipment, safety instructions, and know-how to do a job properly and safely. If a condition is described, DO NOT
assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See your dealer for information on whether your
vehicle may benefit from the information.
