2022 Hyundai Ioniq 5 — Should You Buy One?

Typical asking price: $26,000–$36,000. There are 2 high-severity known issues you need to know before handing over a check.

Kestrel Take

800-volt architecture means it fast-charges faster than almost anything at any price, and the interior is genuinely special. The one real defect is the ICCU — a converter that fails and leaves the car unable to charge or drive. Hyundai extended coverage. Check it.

Known Issues for the 2022 Hyundai Ioniq 5

Ranked by wallet impact. These are documented, recurring problems — not freak accidents.

ICCU (Integrated Charging Control Unit) failureHigh — wallet impact

The ICCU fails, throwing a warning and leaving the car unable to charge the 12-volt battery or, eventually, to drive. Hyundai issued software updates and extended warranty coverage. Failures often occur with little warning.

Repair cost range: $0 under extended coverage, $2,500-$5,000 without

12-volt battery drain from ICCU faultsHigh — wallet impact

The downstream symptom — a dead 12-volt battery that immobilizes the car even with a full traction pack.

Repair cost range: $200-$400 plus the ICCU repair

Rear window wiper absence and visibilityLow

No rear wiper on many trims, which becomes a real complaint in rain and snow.

Repair cost range: n/a

Cold-weather preconditioning on early softwareMedium

Early builds lacked reliable battery preconditioning, which slows winter fast charging. Software updates improved it.

Repair cost range: $0 OTA or dealer
