Service Procedure
Important: Service Agents must comply with all International, Federal, State, Provincial, and/or Local laws
applicable to the activities it performs under this bulletin, including but not limited to handling, deploying,
preparing, classifying, packaging, marking, labeling, and shipping dangerous goods. In the event of a conflict
between the procedures set forth in this bulletin and the laws that apply to your dealership, you must follow
those applicable laws.
Note: There are only 6 vehicles involved in this field action: 1GYKPDRS1NZ153435, 1GYKPDRS8NZ152878,
1GYKPDRS3NZ153503, 1GYKPCRS6NZ153067, 1GYKPDRS9NZ153036, 1GYKPDRSXNZ153241.

Dealer Responsibility
All new, used, GM Certified Used, courtesy transportation vehicles, dealer shuttle vehicles, etc. in dealers' possession
and subject to this program 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, dealertraded, released to auction, used for demonstration, or any other purpose.
All GM Certified Used vehicles currently in the dealers’ inventory within the Certified Pre-Owned Inventory System
(CPOIS) 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 CPOIS system, or once again be used in the CTP 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 August 31, 2024. 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. A copy of the customer letter is provided in this bulletin for your use in contacting customers. Program followup cards should not be used for this purpose, since the customer may not as yet have received the notification letter.
In summary, whenever a vehicle subject to this program enters your vehicle inventory or is in your facility for service
through August 31, 2024, you must take the steps necessary to be sure the program correction has been made before
selling or releasing the vehicle.

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.
