Condition

Correction

During service, certain 2015-2019 model year various make and model vehicles equipped with OnStar
(RPO UE1), may have received an incorrect and partially programmed/configured replacement OnStar
module. This condition will disable certain OnStar features, including Remote Access (remote start, door
lock/unlock, etc.), Connected Access (vehicle diagnostics, dealer maintenance notification, etc.), and
Unlimited Access (Turn-by-Turn Navigation). The OnStar Safety & Security Plan (Automatic Crash
Response and Stolen Vehicle Assistance) is functional.
Dealers are to replace the OnStar module, program, confirm and register the new module correctly by
pushing the blue button for confirmation with an OnStar advisor.

Note: Use the VIN and the GM Electronic Parts Catalog (EPC) to determine which Communication Interface Module to
order.
The parts required for this program are on restriction and need to be obtained from an Electronic Service Center
(ESC). Please refer to your “involved vehicles listing” before ordering parts. These parts will be on Order Writing control
and all orders placed through GMCCA will cancel.
Important: Dealers should NOT contact SPAC for issues related to ESC parts.
If the dealer has a potential buyback due to a backordered part, the dealer MUST inform both the Electronic Service
Center (ESC) where they placed the order, and the District Manager Aftersales (DMA). The District Manager Aftersales
(DMA) should contact the appropriate supplier representative in the Electronic Service Center Dept. at GMCCA to initiate
the escalation process.

Service Procedure
Replace the Communication Interface Module. Refer to Communication Interface Module Replacement in SI.
•

Press the Blue OnStar button after module programming and configuration is complete and place a call to OnStar
to verify that the new module is working properly. You may need a clear line of sight to the sky if you are unable
to connect to OnStar in the shop. It is not necessary to complete this step a second time if you have already done
it once following SI for the vehicle you are programming.

Dealer Responsibility
All new, used, GM Certified Used, courtesy transportation vehicles, dealer shuttle vehicles, etc. in dealers' possession
and subject to this program must be held and inspected/repaired per the service procedure of this bulletin before
Page 2 of 4

Customer Satisfaction Program
N192218430 Incorrect OnStar Module
customers take possession of these vehicles. Involved vehicles must be held and not delivered to customers, dealertraded, 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 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 CPOIS system, or once again be used in the CTP 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 August 31, 2021. 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 followup 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 August 31, 2021, you must take the steps necessary to be sure the program correction has been made before
selling or releasing the vehicle.
Dealer Reports
For dealers with involved vehicles, a listing with involved vehicles has been prepared and will be provided to U.S. and
Canadian dealers through the GM GlobalConnect Recall Reports, or sent directly to export dealers. 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 – For USA & Canada
Courtesy transportation is available for customers whose vehicles are involved in a product program and still within the
warranty coverage period. See General Motors Service Policies and Procedures Manual, Sections 1.4 and 6.1.10, for
courtesy transportation program details.
Customer Notification
USA & Canada - General Motors will notify customers of this program on their vehicle (see copy of customer letter included
with this bulletin).
Customer Reimbursement
Customer requests for reimbursement of previously paid repairs to correct the condition described in this bulletin are to
be submitted to the dealer prior to or by August 31, 2020. See General Motors Service Policies and Procedures Manual,
Section 6.1.11 – Product Field Action Customer Reimbursement Procedure (USA & Canada) or local Policies and
Procedures, for details.

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.

N192218430 Incorrect OnStar Module
This notice applies to your vehicle, VIN: ________________________________
Dear General Motors Customer:
We have learned that your 2015-2019 model year various make and model vehicle equipped with OnStar, may have
received an incorrect and partially programmed/configured replacement OnStar module. This condition will disable
certain OnStar features, including Remote Access (remote start, door lock/unlock, etc.), Connected Access (vehicle
diagnostics, dealer maintenance notification, etc.), and Unlimited Access (Turn-by-Turn Navigation). The OnStar Safety
& Security Plan (Automatic Crash Response and Stolen Vehicle Assistance) is functional.
Your satisfaction with your GM vehicle is very important to us, so we are announcing a program to prevent this condition
or, if it has occurred, to fix it.
What We Will Do: Your GM dealer will replace the OnStar module, program, confirm and register the new module
correctly by pushing the blue button for confirmation with an OnStar advisor. This service will be performed for you at
no charge until August 31, 2021. After that, any applicable warranty will apply.
What You Should Do: To limit any possible inconvenience, we recommend that you contact your dealer as soon as
possible to schedule an appointment for this repair. By scheduling an appointment, your dealer can ensure that the
necessary parts will be available on your scheduled appointment date.
Reimbursement: Even though you may have previously had repairs for this condition, you will still need to take your
vehicle to your dealer for additional repairs. If you have already paid for repairs for the condition described in this letter,
please complete the enclosed reimbursement form and present it to your dealer with all required documents. Working
with your dealer will expedite your request, however, if this is not convenient, you may mail the completed
reimbursement form and all required documents to Reimbursement Department, PO Box 33170, Detroit, MI 482325170. The completed form and required documents must be presented to your dealer or received by the
Reimbursement Department by August 31, 2020, unless state law specifies a longer reimbursement period.
If you have any questions or concerns that your dealer is unable to resolve, please contact the appropriate Customer
Assistance Center at the number listed below.
