Hyundai, Kia and Genesis Extend EV Charger Warranty to 15 Years in Australia

Hyundai, Kia and Genesis have rolled out an extended 15-year or 300,000 km warranty on the Integrated Charging Control Unit (ICCU) for early Australian deliveries of their E-GMP-platform EVs and a handful of related Genesis models. The new cover, which mirrors a similar move in Europe, follows customer reports of ICCU failures (some of which earlier triggered a recall covering a loss-of-motive-power risk).

The previous warranty terms were five years for Hyundai and Genesis, and seven years for Kia. The 15-year extension is a meaningful upgrade for buyers of secondhand E-GMP EVs in particular. It also resets one of the lingering question marks around resale value on early Ioniq 5 / EV6 / GV60 examples.

What is the ICCU and why does it matter?

The ICCU sits inside every E-GMP-platform EV and bundles two things into one box: the low-voltage DC-DC converter (the EV equivalent of an alternator, which keeps the 12V auxiliary battery topped up) and the bidirectional onboard charger, which converts AC power from a wall socket into DC for the high-voltage battery. The same hardware runs the reverse path for V2L (vehicle-to-load) output, the popular feature that lets you run a fridge or power tools off the car.

Replace one out of warranty and the bill is in the thousands. That is why the jump from a 5-year to a 15-year coverage window is a big deal for owners. It is one of the most expensive non-battery components on the platform.

Models covered

Hyundai Australia confirmed to media that the extension applies to specific build-date ranges. Here is the full list as it stands at publication:

The G80 EV and GV70 EV ride on different platforms to the rest of the list (they are EV conversions of existing combustion models rather than purpose-built E-GMP cars), but they share enough drivetrain hardware with the E-GMP cars to be caught by the same fault pattern.

What is not covered

Kia Australia has been explicit that the EV9 and the freshly facelifted MY26 EV6 are not part of this extension. That likely reflects either a revised ICCU design or different supplier lot, and is consistent with Kia's framing of this as a fix for a known build-window issue rather than a blanket platform-wide concession.

Hyundai's Elexio mid-size SUV (built in China) and the upcoming Ioniq 3 hatch use a different platform too, and are not affected.

What it means if you are buying one used

For secondhand buyers this is genuinely good news. A 2022 Ioniq 5 bought today still has 11 to 12 years of ICCU coverage left on it under the new policy, plus its remaining factory new-vehicle warranty. The 300,000 km cap is high enough that almost no privately driven EV will hit it.

Combined with the broader EV battery warranty conventions already in place (typically 8-10 years on the high-voltage pack), the practical effect is that the most expensive parts of the car (battery + ICCU) are now mostly covered for the lifetime that an Australian buyer is likely to keep the vehicle.

If you are looking at a used Kia EV6, Ioniq 6 or Genesis GV60, get the dealer to confirm the VIN has had any outstanding ICCU recall remedies completed. The extended warranty applies regardless, but you don't want a known failure mode hanging over the car.

The bigger picture

Hyundai-Kia-Genesis is not the only manufacturer to push warranty terms outwards in response to early-EV reliability concerns. Tesla offers an 8-year drive-unit warranty on Model S/X, and BYD's blade-battery cars like the Atto 1 ship with an 8-year battery warranty by default. The Korean group's 15-year ICCU policy is at the upper end of what any mainstream brand currently offers on a single drivetrain component.

For owners of MY22-MY24 E-GMP cars, the uncertainty around long-term ICCU reliability has been one of the louder complaints in owner forums and trade-in valuations. This extension does not fix the underlying engineering question, but it does answer the financial one.
