Transfers to a second ownerYes. Any remaining portion of any warranty is fully transferable to subsequent owners except the 120 months/100,000 miles Power Train (Original Owner) warranty
Clock startsDate of First Service: the earliest of delivery to the first retail purchaser, lease, or placement into service as a company vehicle such as a demonstrator, rental or fleet vehicle
Outside the EV System WarrantyAny other electrical components in the vehicle, such as (but not limited to) the traditional 12 volt car battery, alternator, or other starter components

What is not covered

Every manual from 2019 to 2026 excludes EV System and Lithium-Ion Polymer Battery damage or failure caused by:

  • Ambient temperatures above 122F (50C) for over 24 hours, or storage below -22F (-30C) for over seven days.
  • Leaving the vehicle over 14 days where the battery reaches a zero or near zero state of charge.
  • Physically damaging the battery, intentionally attempting to reduce its life, exposing it to a direct flame, or immersing any portion of it in water or fluids.
  • Opening the battery enclosure, or having it serviced by someone other than a Kia certified EV technician.
  • Neglecting to follow correct charging procedures, or use of incompatible charging devices.
  • Incidental or consequential damage caused by the failure to repair an existing problem.

The 2023 to 2026 manuals also exclude damage to the charge port or vehicle components caused by a public charger, a non-Kia supplied charge cord, or other third party electric vehicle service equipment (EVSE).

Scope note

US market, model years 2019 through 2026, each from the Warranty and Consumer Information Manual that Kia's owner portal lists under that Niro EV model year; the kiatechinfo.com file links open after the manual is selected on that portal. The manuals name no model, except that Kia files the 2020 one as the Niro EV's ("20MY DE EV WCIM"). The manual delivered with a specific car is the authority for that car.
