Special Order only. DRO’s may be cancelled. Place the VIN # in the notes field of the order. If there is no VIN in the

to confirm RIM managed status. Parts may have quantity limiters in effect.
For Export: Please contact CCA’s Export Order Fulfillment group to place the order on your behalf.

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 February 28, 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. 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 February 28, 2026, you must take the steps necessary to be sure the program correction has been made before
selling or releasing the vehicle.

warranty coverage period. See General Motors Service Policies and Procedures Manual for courtesy transportation

with this bulletin).

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.

This notice applies to your vehicle, VIN: ________________________________
Dear General Motors Customer:
Our records indicate that, at the time you purchased or leased your GM vehicle, the vehicle was not equipped with
some of its intended features due to a nationwide parts shortage.
We are pleased to inform you that your GM dealer is now ready to enable your front seat cushion vent blowers. We
recommend that you contact your GM dealer as soon as possible to schedule an appointment for this retrofit. By
scheduling an appointment, your dealer can order the necessary parts to be available on your scheduled appointment
date.
Please note, you may have received a letter from GM advising you that parts were available to enable your
heated/ventilated seats. These are separate retrofits, and both require installation for full functionality of your ventilated
seats. If you have not already done so, you may have both features enabled (heated/ventilated seats and front seat
cushion vent blowers) at the same time when you schedule your appointment for this retrofit.
What We Will Do: Your GM dealer will install the required parts to enable your front seat cushion vent blowers. This
service will be performed for you at no charge until February 28, 2026.
What You Should Do: We recommend that you contact your GM dealer as soon as possible to schedule an
appointment for this retrofit.
If you have any questions or concerns that your dealer is unable to resolve, please contact the appropriate Customer
Assistance Center at the number listed below.
For the hearing or speech impaired, please contact our Customer Assistance Center using the Telecommunication
Relay Service by dialing 711 then providing the appropriate Customer Assistance Center number for your vehicle.
