subscription, the OnStar® module is to be deactivated after replacement.
VEHICLES INVOLVED
All involved vehicles are identified by Vehicle Identification Number on the Investigate Vehicle
History screen in GM Global Warranty Management system. Dealership service personnel
should always check this site to confirm vehicle involvement prior to beginning any required
inspections and/or repairs. It is important to routinely use this tool to verify eligibility because not
all similar vehicles may be involved regardless of description or option content.

Bulletin No.: 14395A

For dealers with involved vehicles, a listing with involved vehicles containing the complete vehicle
identification number, customer name, and address information has been prepared and will be
provided to dealers through the GM GlobalConnect Recall Reports. Dealers will not have a report
available if they have no involved vehicles currently assigned.
The listing may contain customer names and addresses obtained from Motor Vehicle Registration
Records. The use of such motor vehicle registration data for any purpose other than follow-up
necessary to complete this program is a violation of law in several states/provinces/countries.
Accordingly, you are urged to limit the use of this report to the follow-up necessary to complete
this program.
PART INFORMATION
Parts required for this program are to be obtained from the Electronic Service Center (ESC). A
Technical Assistance Center (TAC) case has been set up for the involved vehicles. The case
number is identified in the customer letter. The customer is being instructed to inform the dealer
of this number when scheduling an appointment so that the module can be ordered available on
the scheduled appointment date.

file. Regardless of the customer’s OnStar account status, dealers must press the Blue OnStar
button and have OnStar Customer Care activate the unit for OnStar services or have the unit
disabled and the Wi-Fi Demo message turned-off if the customer does not have an active OnStar®
subscription.

 An OnStar® button press to the OnStar® call center is required to complete the
procedure.
 To fully activate an OnStar® module, both the setup (programming) and activation
request (Blue Button call) procedures must be completed on all vehicles with and without
an active OnStar® subscription to ensure the unit has been setup properly for the vehicle
it has been installed into and also to update the OnStar® with the correct unit information.
 To initialize the Turn-by-Turn feature, the vehicle must first be driven in open sky
condition at speeds greater than 10 mph (16 km/h) or more for a minimum of 5 miles (8
km) , and perform at least 2 left and 2 right 90 degree turns coming to complete stops
prior to each turn.

COURTESY TRANSPORTATION – For US and Canada
The General Motors Courtesy Transportation program is intended to minimize customer
inconvenience when a vehicle requires a repair that is covered by the New Vehicle Limited
Warranties. The availability of courtesy transportation to customers whose vehicles are within the
warranty coverage period and involved in a product program is very important in maintaining
customer satisfaction. Dealers are to ensure that these customers understand that shuttle service
or some other form of courtesy transportation is available and will be provided at no charge.
Dealers should refer to the General Motors Service Policies and Procedures Manual for Courtesy
Transportation guidelines.

All unsold new vehicles in dealers' possession and subject to this program must be held and

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 November 30, 2017, 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.
