ATTENTION: ALL DEALER PARTS & SERVICE MANAGERS
Kia America, Inc. is conducting a Voluntary Service Campaign to replace the gear oil in the front motor and gear reduction
assembly and fill it to the factory-specified amount in the following vehicles:
•

Certain 2023-2024 MY EV6 vehicles, manufactured from December 14, 2022 through February 22, 2024

•

Certain 2023-2024 MY Niro EV vehicles, manufactured from December 12, 2022 through February 7, 2024

During the production of the subject vehicles, the amount of gear oil in the front motor and reduction gear assembly may
have been filled below factory specification. If the gear oil level is lower than Kia’s factory specifications, the subject vehicles
may eventually produce a grinding or whining noise from the front of the vehicle while driving.
Dealers will replace the gear oil in the front motor and gear reduction assembly and fill it to the factory-specified amount.
This campaign will be performed free of charge at no cost to the customer.
The Technical Service Bulletin that provides vehicle inspection and repair procedures, affected VIN production range, and
warranty claim information will be posted on the Kia Global Information System (KGIS) at www.kiatechinfo.com during the
week of August 20, 2025.
Enclosed you will find a copy of the owner notification letter and a Q&A Guide, both of which describe the issue. Kia will
mail notices to the affected vehicle owners beginning on August 22, 2025.
Please make personnel in your dealership familiar with the details of this Voluntary Service Campaign so they may respond to
customer inquiries and requests appropriately. This Voluntary Service Campaign is an opportunity for your service
department to deliver an exceptional service experience to customers who may not have otherwise scheduled service.
Providing customers with easy scheduling and timely service increases the chance they will return to your service department
for future service needs.
LEGAL PRIVACY LIABILITY NOTICE: Pursuant to the terms of the Dealer Sales and Service Agreement and the GrammLeach-Bliley federal consumer privacy act, you are required to keep confidential any and all information and documents
provided to you by Kia America, Inc. or generated by you in the conduct of carrying out work under that Agreement
regarding Kia vehicle purchasers and owners, including but not limited to warranty claim information. Kia dealers may use
such owner information for the sole purpose of conducting and performing this voluntary service campaign, and for no other
purpose.
If you have any questions, please contact your Kia District Parts and Service Manager.
