Program Bulletin
CUSTOMER SATISFACTION PROGRAM
SUBJECT:
OnStar System Inoperative – Chip Corruption
MODELS:
2015 GM Passenger Car
2015 GM Light Duty Trucks
Equipped with Gen 10 OnStar®
When a customer calls to schedule an appointment for this program, please place your order for
the module. This will ensure that the necessary parts will be available on the scheduled
appointment date. It is important to note that this program is independent from the OnStar 3G /4G
Hardware Program, impacting a separate group of vehicle owners. For this Customer Satisfaction
Program, dealers are responsible for ordering the part.
THIS PROGRAM IS IN EFFECT UNTIL DECEMBER 31, 2017.
CONDITION
On certain 2015 model year GM passenger cars and light duty trucks, equipped with Gen 10
OnStar®, the embedded phone flash memory chip may become corrupted, causing the OnStar®
system to become inoperative.
CORRECTION
Dealers are to replace the vehicle communication interface module (VCIM).
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.
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.

COURTESY TRANSPORTATION
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.

CUSTOMER NOTIFICATION
General Motors will notify customers of this program on their vehicle (see copy of customer letter
included with this bulletin).
DEALER PROGRAM RESPONSIBILITY
All unsold new vehicles in dealers' possession and subject to this program must be held and
inspected/repaired per the service procedure of this program bulletin before customers take
possession of these vehicles. Dealers are to service all vehicles subject to this program at no
charge to customers, regardless of mileage, age of vehicle, or ownership, through December 31,
2017.
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 December 31, 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.

This notice applies to your  VIN: _______________________
Your vehicle is involved in Customer Satisfaction Program 15086.
Dear General Motors Customer:
We’re happy to have you as part of the OnStar® family and appreciate the confidence you have
in us. As an OnStar customer, we provide you with the latest software updates to maintain the
performance of your OnStar hardware and system.
We recently tried to provide such a software update to your OnStar hardware for your 2015
model year GM vehicle. Your system, however, was not able to be updated remotely and as a
result some of your OnStar system functions may not be working as expected.
It is important to us that your OnStar system is functioning properly to avoid any possible lapse
in service.
What Your Dealer Will Do: To address this software issue, we have asked dealers to replace
the OnStar hardware on your vehicle. Your GM dealer will install new OnStar hardware. This
service will be performed for you at no charge until December 31, 2017.
What You Should Do: We recommend that you contact your GM dealer as soon as possible to
schedule an appointment for this repair. Please be sure to reference Customer Satisfaction
Program 15086. By scheduling an appointment, your dealer can ensure that the
necessary parts will be available on your scheduled appointment date.
We sincerely regret any inconvenience or concern that this situation may cause you.

General Motors is releasing Customer Satisfaction Program 15086 today. The
total number of U.S. vehicles involved in the first phase is approximately
10,500. Please see the attached bulletin for details.
Over the next several months, OnStar will attempt an over-the-air update to the
OnStar module in certain vehicles. If the attempt is unsuccessful, the customer
will be sent a letter asking them to take their vehicle to their dealer for an OnStar
module replacement and the VIN will be added to IVH. This process will occur
approximately every 45 days until all involved vehicles have been either
reprogrammed or have been identified as needing the module replaced.
In addition, customers will be asked to provide their dealer with their VIN when
scheduling an appointment for service. Dealers are to order the module so it will
be available on the schedule appointment date. Do not call the Technical
Assistance Center (TAC) for a part approval. All affected VINs in this program
have been pre-approved with these ESCs. Please see the Parts Information
section of the bulletin for details.
Customer Letter Mailing
The customer letter mailing for this first phase will begin on August 4, 2015.
