Important: Service agents must comply with all International, Federal, State, Provincial, and/or Local laws

applicable to the activities it performs under this bulletin, including but not limited to handling, deploying,

preparing, classifying, packaging, marking, labeling, and shipping dangerous goods. In the event of a

conflict between the procedures set forth in this bulletin and the laws that apply to your dealership, you

must follow those applicable laws.

Effective January 1, 2024 (U.S.) and February 15, 2024 (Canada), GM is changing part of the process for LithiumIon battery packs and modules (sections and kits) used for warranty and recall repairs. Rather than dealers

exchanging battery packs/modules with no upfront cost and receiving an administrative allowance upon job

completion, dealers will now order and pay for battery packs/modules upfront and receive their approved parts

markup based on the Dealer price that will now be published in GM’s Electronic Parts Catalog (EPC) upon

submission of a claim in accordance with GM’s Service Policies & Procedure Manual.

This enhanced structure will help further customer EV adoption by making repairs for battery packs/modules

affordable for customers in the event a retail repair is required. The availability of affordable EV repairs will also help

drive these customers back to GM dealerships for their service needs.
New Interim Additional Labor Compensation

To respond to concerns raised that dealerships are learning new technology and new processes related to the

continued EV transition, including developing efficient repair, safety, return, and other associated processes, GM will

provide dealers with the ability to claim up to $500 ($624 in Canada) in additional labor on all job cards for battery

pack/module replacements. This Interim Additional Labor Compensation is intended to be phased out over time and

will be re-evaluated after December 31, 2025. During this acclimation period, dealers are encouraged to take

advantage of the job time study amendment process to provide feedback if tasks are consistently taking longer than

the times listed in GM's time guide.
Ordering

The logistics behind the Lithium-Ion exchange program will remain in place: dealers will still order the subject

Lithium-Ion battery packs and modules through GM’s authorized Battery Service Centers (BSCs), all orders must be

for an existing VIN requiring service, and these orders must still be pre-approved through the GM Technical Assistance Center (TAC). Once approved through TAC, contact the following for part exchange:

• U.S Dealers (Ultium Vehicles): Contact Label Master via Global Connect, EV High Voltage Battery Orders &

Returns, Label Master Portal or 1-844-931-4966.

• U.S. Dealers (Non-Ultium Vehicles): Contact Spiers New Technologies via Global Connect, EV High Voltage

Battery Orders & Returns, SNT ALFRED portal or (833) 334-6272.

• Canada Dealers: Contact York Electronic at (888) 650-9675. York Electronics is the GM authorized Battery

Service Center (BSC) in Canada.

The Battery Service Center (BSC) will notify GM of the order which will generate an invoice to the dealer for the cost

of the Lithium-Ion battery or module based on current catalog pricing.
