Description
Hands-Free Lane Following
(Super Cruise)
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
A software update package is available for the 2018 Cadillac
CT6 with Super Cruise.
The enhanced Super Cruise software will improve lane centering and add descriptive instrument cluster
messaging that will allow drivers to better understand why Super Cruise is unavailable or why Super
Cruise needs to disengage and return control to the driver. We’ve heard feedback from customers that
they would like additional information on the operation of the Super Cruise feature and we’ve added new
descriptive messaging to address this request.
As a result of the software updates being provided, system performance will be enhanced in the following
ways:
•
Easier to Engage Super Cruise. Customers will notice in some situations the Super Cruise
symbol now appears more easily when centering their vehicle in the lane allowing them to
engage Super Cruise. This includes the ability to more easily reengage Super Cruise after
making a lane change.
•
Correction
Improved Adaptive Cruise Control
. The adaptive cruise control
portion of Super Cruise has
been enhanced to provide smoother acceleration and braking behavior. Certain 2018 model
year Cadillac
CT6 vehicles, equipped with Super Cruise, may have a condition in which the
vehicle, under certain road conditions may shift left or right while traveling in its lane during
Super Cruise operation. Additionally, if the Super Cruise system is not able to be engaged, the
cluster messaging only shows “unavailable” without further details on why the system is not
available.
Dealers are to update the Super Cruise software, and provide the customer with an owner manual insert
that outlines the new available cluster messaging.

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 May 31, 2020. 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 May 31, 2020, 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).
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.
