Involved vehicles are marked “open” on the Investigate Vehicle History screen in GM Global Warranty Management
system. This site should always be checked to confirm vehicle involvement prior to beginning any required inspections
and/or repairs.
Condition
Correction
The brake system control module software in these vehicles may contain an error. If (i) the vehicle is
started remotely using the MyChevrolet, MyGMC, or MyCadillac mobile app or (ii) the driver enters the
vehicle and waits five or more minutes before starting the vehicle using the ignition, this software error
can, in rare cases, disable the vehicle’s electronic brake assist and illuminate the ESC, ABS and BRAKE
telltales. This occurs at startup and the telltales are illuminated before the driver puts the vehicle into
gear.
Dealers will reprogram the brake system control module.
Parts
No parts are required for this repair.

Service Procedure
Important: Carefully read and follow the instructions below.
•
Ensure the programming tool is equipped with the latest software and is securely connected to the data link connector.
If there is an interruption during programming, programming failure or control module damage may occur.
•
Stable battery voltage is critical during programming. Any fluctuation, spiking, over voltage or loss of voltage will
interrupt programming. Install a GM Authorized Programming Support Tool to maintain system voltage. Refer to
www.gmdesolutions.com for further information. If not available, connect a fully charged 12 V jumper or booster
pack disconnected from the AC voltage supply. DO NOT connect a battery charger.
•
Turn OFF or disable systems that may put a load on the vehicles battery such as; interior lights, exterior lights
(including daytime running lights), HVAC, radio, etc.
•
Clear DTCs after programming is complete. Clearing powertrain DTCs will set the Inspection/Maintenance (I/M)
system status indicators to NO.

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
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 February 28, 2022. 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, through February 28, 2022, whenever a vehicle subject to this field action enters your vehicle inventory you
must take the steps necessary to ensure the program correction has been made before selling the vehicle. In addition,
for vehicles entering your facility for service, you are required to ensure the customer is aware of the open field action
and make every reasonable effort to implement the program correction as set forth in this bulletin prior to 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).
Export - Letters will be sent to known owners of record located within areas covered by the US National Traffic and Motor
Vehicle Safety Act. For owners outside these areas, dealers should notify customers using the attached sample letter.
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.

Dear General Motors Customer:
We have learned that the brake system control module software in your 2020 model year Cadillac XT5, Cadillac XT6,

started remotely using the MyChevrolet, MyGMC or MyCadillac mobile app or (ii) the driver enters the vehicle and waits
five or more minutes before starting the vehicle using the ignition, this software error can, in rare cases, disable the
vehicle’s electronic brake assist and illuminate the ESC, ABS and BRAKE telltales. This occurs at startup and the
telltales are illuminated before the driver puts the vehicle into gear. Until your vehicle is repaired, do not use the
MyChevrolet, MyGMC or MyCadillac app to remote start your vehicle.
Your satisfaction with your 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 reprogram the brake system control module. This service will be performed for
you at no charge until February 28, 2022. 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. Until your vehicle is repaired, do not use the MyChevrolet, MyGMC
or MyCadillac app to remote start your vehicle. If after starting your vehicle, you see multiple warning lights and
warning messages in your vehicle’s driver information center display, do not drive your vehicle. Contact the
appropriate Customer Assistance Center using the numbers provided below for assistance. Customer Assistance will
