North American Charging Standard (NACS) DC Adapters are designed for electric vehicles with a native CCS1
charge port, offering the ability to charge on a NACS public charger. Customers are advised to contact EV Concierge
(1-833-64POWER) for assistance on adapter usage and charging questions.
The adapters are covered under the terms of a 1-year Limited Parts Warranty from the date of purchase. The limited
warranty is only valid for the original part purchaser and is not transferrable.
This Warranty does NOT cover:
• Damage or failure due to negligence, alteration, accident, abuse, improper installation, or use for a purpose
which the product is not designed or approved by GM
• Loss of time, inconvenience, loss of use of the vehicle, or other consequential damages
• Labor cost for electrical diagnosis
• Products utilized for vehicles registered and normally operated outside of the United States or Canada
Dealers are to conduct a visual inspection of the adapter for signs of abuse or damage. (Damage or abuse would not
be considered as a warrantable replacement).
Dealers are to verify warranty eligibility by requesting from the customer their original receipt or proof of purchase. A
copy is to be retained by the dealer in order to support the parts replacement transaction.
Dealers should provide consumer with replacement adapter following the replacement process listed below. The
dealer must submit an over-the-counter warranty claim (ZPTC Transaction Type) for reimbursement. Subsequent
replacements under the warranty will receive the balance of the original warranty period. As part of our standard
warranty policy, the subsequent parts would only be warranted for the remainder of the original warranty.
Replacement Process (for USA only):
• Due to limited supply volume and lack of dealer stocking at launch, ADIs will be able to provide adapter
warranty replacement parts.
• ADIs will be advised to set aside a certain percentage for warranty replacement stock. Dealers will be able to
request a ‘pull’ from this volume.
Replacement process in Canada to follow normal process for GM Genuine Parts using Labor Operation code
mentioned below.
Adapters replaced under warranty should be retained in accordance with currently published warranty parts handling
procedures and retention policies.

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 equipment, tools, 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 GM dealer for information on whether your vehicle may benefit from the
information.
