Dealer Responsibility
All new, used, GM Certified Pre-Owned (CPO), courtesy transportation vehicles, dealer shuttle vehicles, CarBravo, etc.

this bulletin before customers take possession of these vehicles. Involved vehicles must be held and not delivered to

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 the end date as noted in the Attention box. 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 follow-up 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 the end date as noted in the Attention box, you must take the steps necessary to be sure the program correction
has been made before selling or releasing the vehicle.
