DEALER PROGRAM RESPONSIBILITY
Dealers must take the steps necessary to ensure that the service update correction has been
made to all involved vehicles in dealer inventory before selling or dealer-trading the vehicle, but
no later than February 28, 2017.
All new, used, GM Certified Used, courtesy transportation vehicles, dealer shuttle vehicles, etc. in
dealers' possession and subject to this bulletin 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 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

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.

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.
