VOLUNTARY SERVICE CAMPAIGN
July 18, 2025
Dear KiaeBay logo EV6 Vehicle Owner:
KiaeBay logo America, Inc. is conducting a Voluntary Service Campaign to update the Power-net Domain Controller (PDC) with
improved software to prevent damage to the pre-charge resistor in certain 2025 MY EV6 vehicles. Our records indicate that
you own or lease one of the potentially affected vehicles.
Why is KiaeBay logo Conducting This Service Campaign?
Due to a PDC software logic error in your vehicle, the pre-charge resistor may become damaged if the vehicle is abnormally
turned off (e.g., turned off while the gear selector is in Neutral). If the pre-charge resistor becomes damaged, you may

experience illumination of the Service warning light

, “Check electric vehicle system

” message, and/or the

vehicle may not go into READY mode. (More information on starting your vehicle and READY mode can be found in Section
1-32 of your vehicle’s Owner’s Manual.)
What Will KiaeBay logo Do?
KiaeBay logo dealers will update the PDC logic with improved software to prevent damage to the pre-charge resistor when the vehicle
is abnormally turned OFF (e.g., turned off while the gear selector is in Neutral). This campaign will be performed free of
charge at no cost to you.
What Should You Do?

IMPORTANT: You may experience illumination of the Service warning light, “Check electric vehicle system”
message, and/or be unable to start your vehicle if there has been damage to the pre-charge resistor. If this occurs,
you should have your vehicle towed to the nearest authorized KiaeBay logo dealership as soon as possible. You can request
roadside assistance directly from your 2025 KiaeBay logo EV6, either through the infotainment system (select KIAeBay logo CONNECT,
Press ROADSIDE ASSISTANCE) or the ROADSIDE ASSIST button

on the overhead console or rearview mirror.

Both methods should automatically connect you to a roadside assistance representative. You may also call 1-800333-4542 or request roadside assistance online at kia.rsahelp.com.

Please contact your KiaeBay logo dealer to schedule a service appointment at your earliest convenience. The time required to
perform the campaign can vary depending on the dealer’s work schedule, so a service appointment is an important way
of minimizing your inconvenience. Please present this notice when you arrive at the KiaeBay logo dealer.

To find your nearest dealer, visit www.kia.com and click the “Find Dealer” button in the upper right corner (“Dealers” on a
mobile device).

request in a timely manner, we suggest that you call KiaeBay logo’s Customer Care Center at 1-800-333-4542 (Monday through Friday,
