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
General Motors has decided to conduct a voluntary emissions recall involving certain 2018 Chevrolet
City Express vehicles. The engine control module (ECM) in these vehicles may not be able to properly
diagnose reduced efficiency issues within the catalytic converter. If the catalytic converter’s efficiency
would become reduced, tailpipe emissions could exceed acceptable standards without illuminating the
Malfunction Indicator Lamp (Check Engine Light).
Dealers are to reprogram the engine control module.
Parts
No parts are required for this repair.

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

Dealers are to service all vehicles subject to this recall at no charge to customers, regardless of mileage, age of vehicle,
or ownership, from this time forward.
Customers who have recently purchased vehicles sold from your vehicle inventory, and for which there is no customer
information indicated on the dealer 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. Recall 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 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.
***THE FOLLOWING 2 PARAGRAPHS ARE NOT FOR CANADA OR EXPORT***
When a California emissions recall is completed by a GM dealer, the dealer must provide the vehicle owner a “Proof of
Correction Certificate” which the owner may need to present to the California Department of Motor Vehicles (DMV) when
renewing their vehicle registration. Without this correction certificate, the owner may be unable to renew their vehicle
registration.
Additional Certificates can be obtained, at no charge, from the 1Store application in GlobalConnect. Request GM Item
Number 1825 when ordering.
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 recall 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 recall.
Customer Notification
USA & Canada - General Motors will notify customers of this recall on their vehicle (see copy of customer letter included
with this bulletin).
In order to ensure full protection under the emission warranty, and the right to participate in future recalls, the customer
notification letter recommends that customers have their vehicles serviced as soon as possible. It also advises that failure
to do so could legally be determined to be lack of proper maintenance. The vehicle may fail a state or local emission
inspection test if the recall work is not completed.
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 June 30, 2021. See General Motors Service Policies and Procedures Manual,
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.

June 2020
This notice applies to your vehicle, VIN: _____________________________________
Dear General Motors Customer:
This notice is sent to inform you that General Motors is conducting a voluntary emission recall that includes your
vehicle.
Reason for This Recall: Your 2018 model year Chevrolet City Express vehicle, may be equipped with an improperly
functioning on-board emission-related diagnostic system that violates California standards and regulations. The engine
control module (ECM) in these vehicles may not be able to properly diagnose reduced efficiency issues within the
catalytic converter. If the catalytic converter’s efficiency would become reduced, tailpipe emissions could exceed
acceptable standards without illuminating the Malfunction Indicator Lamp (Check Engine Light).
What Will Be Done: Your GM dealer will reprogram the ECM. This service will be performed for you at no charge.
Eligibility for this service will not be denied solely due to your Chevrolet City Express vehicle having non-GM parts or
repairs performed by outlets other than a GM franchised dealer.
How Long Will the Repair Take? Because of service scheduling requirements, it is likely that your dealer will need
your vehicle longer than the actual service correction time of approximately 35 minutes.
What You Should Do: Please contact your GM dealer after June 5, 2020, to arrange a service date. Instructions for
making this correction have been sent to your dealer. Please ask your dealer if you wish to know how much time will be
needed to schedule, process, and repair your vehicle.
Reimbursement: Even though you may have already had repairs for this condition, you will still need to take your
vehicle to your dealer for additional repairs. If you have 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 48232-5170. The
completed form and required documents must be presented to your dealer or received by the Reimbursement
Department by June 30, 2021, unless state law specifies a longer reimbursement period.
If you have any questions or need any assistance, just contact your dealer or the appropriate Customer Assistance
Center at the number listed below.

Emission Law Information: In order to ensure your full protection under the emission warranty made applicable to
your vehicle by state and federal law, and your right to participate in future recalls, it is recommended that you have
your vehicle serviced as soon as possible. Failure to do so could legally be determined to be lack of proper
maintenance of your vehicle. Also, your vehicle may fail a state or local emission inspection if this recall is not
accomplished.
IMPORTANT MESSAGE FOR CALIFORNIA RESIDENTS
The California Air Resources Board (CARB) requires vehicle emission recalls be completed prior to California
registration renewal. Uncorrected emission recalls will result in the inability to renew your California vehicle registration.
At the time of emission recall completion, your California dealer will issue a "Proof of Correction Certificate". Keep this
certificate and, if required, present it to the Department of Motor Vehicles when renewing your California registration as
proof of recall completion.
We are sorry to cause you this inconvenience; however, we have taken this action in the interest of your continued
satisfaction with our products.
