Revised Parts Table
Models: 2019 – 2020 Chevrolet Silverado 4500HD/5500HD/6500HD
To:
All General Motors Medium Duty Dealers
This bulletin is being revised to update the Parts table. Please discard all
previous copies of N212327100.
We revised the bulletin because the orders were coming in incorrectly and
missing the clear overlay. These labels are now in a kit and dealers can order
with the updated part number in this bulletin revision when needed. The
inventory is limited, and dealers are not to order unless it is critical. Dealers who
have pending orders with the GM 1Store will be cancelled as the labels were
mailed to dealers on May 21, 2021.

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 2019 - 2020
Chevrolet Silverado 4500HD, 5500HD and 6500HD vehicles. The Vehicle Emissions Control Information
(VECI) label may contain an incorrect certification group identifier.
Since a new label can be easily installed, and to reduce customer inconvenience, the label will be sent
directly to customers of record along with the installation instructions. Customers may install the label or,
if they desire, they may take the label to their dealer for installation at no charge.
Parts
The VECI label overlays will be mailed directly to the customers. Dealers with unsold inventory will also receive labels
via USPS. Due to low inventory at the GM 1Store, dealers should only order labels if necessary and should check their
parts department for receipt of the mailed labels before ordering. The correct label can be determined using the chart
below, by ordering according to the 12 character code in the bottom left corner of the VECI label. 1Store orders must
contain the Correct GHG Family Name in the OverLimit Reason comment box.

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
take possession of these vehicles. Involved vehicles must be held and not delivered to customers, dealer-traded,
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 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.

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.
Customer Notification
USA & Canada - General Motors will notify customers of this recall on their vehicle (see copy of customer letter included
with this bulletin).
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:

vehicle.
Reason For This Recall: General Motors has decided to conduct a voluntary emissions recall involving certain 2019

following the enclosed instructions. If you desire, however, you may take the label to your dealer for installation. This
service will be performed for you at no charge.

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
