Hyundai Ioniq 5: Battery Warranty

Coverage at a glance

ItemAnswer
Term10 years from the date of original retail delivery or date of first use. The 2022 handbook states the same term
Mileage cap100,000 miles, whichever occurs first
Capacity floorA warranty repair or replacement must restore at least the energy capacity the battery had before the failure, and no less than 70% of original capacity
Normal degradationHyundai's handbook states it both ways; see the bullet below
Replacement packMay be new or refurbished
Transfers to a second ownerHyundai's transfer section names six coverages that transfer and cuts the Powertrain warranty to 5 years/60,000 miles for later owners; the electric-vehicle battery warranty is in neither list
Also coveredBattery Management System, Blower Assembly, Electronic Air Compressor, Power Relay Assembly, Hybrid Starter and Generator, Traction Motor including housing case, Hybrid Power Control Unit, OBC, Electric Power Control unit
TowingCovered on the same clock when the vehicle is inoperable due to a warrantable defect
California 150,000-mile noteDoes not apply. It covers the Plug-in Hybrid Battery on a TZEV-certified vehicle; the Ioniq 5 is battery-electric
  • Hyundai's handbook says both that capacity is "covered not to degrade more than 70% of the original battery capacity" and, in the same section's What is Not Covered, that loss of battery energy or power over time or from usage "is NOT covered under this Hybrid, Plug-in Hybrid, and Electric Vehicle Warranty."

Transfer, as the handbook has it

  • The Summary of Warranty Coverage lists the EV Direct Energy Components row at 10 years/100,000 miles with no original-owner footnote; the Powertrain row below it carries one limiting subsequent owners to 5 years/60,000 miles.
  • Warranty Transferability names six coverages that transfer, and names the Powertrain Limited Warranty as the one that does not; the Hybrid, Plug-in Hybrid, and Electric Vehicle Warranty appears in neither list.

What is excluded

  • Intentional actions, including abusing or destroying the vehicle or ignoring active vehicle warnings.
  • A collision or accident.
  • Servicing or opening of the battery by non-authorized personnel.
  • Physical battery damage, or extending or reducing battery life by physical means, programming or other methods beyond what the owner documentation specifies.
  • Exposing the battery to direct flame, or flooding it.

Scope note

Hyundai publishes one warranty handbook for its whole US lineup, not one per model, and nothing above is specific to the Ioniq 5; it is the coverage Hyundai states for the Direct Energy components that include its High Voltage Battery. The 2022 and 2025 handbooks were opened and read the same on term and mileage; model years 2023, 2024 and 2026 were not checked. The handbook delivered with a specific car governs that car.
