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®
This bulletin has been revised to provide instructions on programming and activating the new
vehicle communication interface module. Please discard all copies of bulletin 15086.
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 and program 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.

customer satisfaction. Dealers are to ensure that these customers understand that shuttle service

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.
