Description

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

Certain 2015-2016 model year Chevrolet Colorado and 2015-2016 model year GMC Canyon vehicles,
may have a condition in which a crack in the heating and cooling module temperature door control shaft
may form and result in inconsistent air discharge temperature control. If the shaft cracks, the air
discharge temperature may be up to 33 degrees Fahrenheit (20 degrees Celsius) cooler than the
requested values, depending on the HVAC mode selected.
Inspect the temperature valve control shaft for cracks. If the shaft is intact, install a reinforcing clamp
around the temperature valve shaft to prevent the shaft from cracking. If more than one crack is present,
replace the temperature control valve.

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 October 31, 2018. 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 October 31, 2018, 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, Section 6.1.10 – Courtesy
Transportation, for details.
Customer Notification

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 your 2015-2016 model year Chevrolet Colorado or 2015-2016 model year GMC Canyon may
have a condition in which a crack in the heating and cooling module temperature door control shaft may form and result
in inconsistent air discharge temperature control. If the shaft cracks, the air discharge temperature may be up to 33
degrees Fahrenheit (20 degrees Celsius) cooler than the requested values, depending on the HVAC mode selected.
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 inspect the temperature valve control shaft for cracks. If the shaft is intact, they
will install a reinforcing clamp around the temperature valve shaft to prevent the shaft from cracking. If more than one
crack is present, the temperature control valve will be replaced. This service will be performed for you at no charge
until October 31, 2018. 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.
