Release Date:
Attention:

October 2020

Revision:

00

Vehicles involved in this recall were placed on stop delivery September 18, 2020. If the vehicle passes
the inspection, the vehicle is released from stop delivery and can be delivered to the customer.
This bulletin contains an inspection procedure for both dealer inventory and customer vehicles. Vehicles
that pass this inspection procedure can be delivered and closed using the “Inspect Catalytic Converter
for Correct Part Number – No Further Action Required” labor code 9105315. It is estimated that a very
small percentage of the involved vehicles will fail the inspection and require part replacement. Vehicles
that DO NOT PASS the inspection must be held and not delivered to customers. This bulletin will
be updated when the required parts become available, at which time those vehicles can be repaired,
closed and delivered.
It is a violation of Federal law for a dealer to deliver a new motor vehicle or any new or used item of motor
vehicle equipment (including a tire) covered by this notification under a sale or lease until the defect or
noncompliance is remedied.
All involved vehicles that are in New and Unsold dealer inventory must be held and not delivered to
customers, dealer traded, or used for demonstration purposes until the inspection contained in this
bulletin has been performed on the vehicle.

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

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 has been prepared and will be available through GM GlobalConnect Maxis
Field Action Reports or sent directly to export dealers. The Inventory tab of the dealer reports will contain VINs that
apply to this recall. This information is intended to assist dealers with the PROMPT COMPLETION of these
vehicles. The Customer In-Service tab will contain customer names and addresses 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 may be a violation of law in several states.
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 for courtesy transportation
program details.
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.

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.

TBD 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 2020 model year Buick Encore GX or 2021 Chevrolet Trailblazer, equipped with a 1.2L
3 cylinder gas engine, may have received the incorrect catalytic converter parts that do not meet all emission system
requirements.
What Will Be Done: Your GM dealer will inspect the catalytic converter and replace if the correct part was not
installed. This service will be performed for you at no charge. Eligibility for this service will not be denied solely due to
your 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 30 minutes.
What You Should Do: Please contact your GM dealer as soon as possible to arrange a service date and to assure
parts availability. 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.
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.
