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.

What we checked

Partly reconciled against public records, 2026-09-11

NHTSA holds 404 owner complaints for the 2022 Hyundai Ioniq 5, across 3 recall campaigns.

A big number here usually means a lot of these were sold, not that it is a bad vehicle — popular models collect more complaints for the same rate of trouble. So the total on its own says little. What is worth reading is the shape of it. 75% of them are about one thing — electrics and electronics. That much concentration is a genuine pattern rather than background noise, and it is the first thing to check on any example you look at.

3 recall campaigns cover this model year. Recalls are repaired free, for any owner, with no time limit on most safety campaigns — but only if someone books it in. Ask the seller to show it was done, or have any dealer check the VIN; it takes them a couple of minutes and costs nothing.

Not written up yet: the fuel system (89 complaints), the transmission and drivetrain (84 complaints). Those groups are in the public record and are not covered by the issues below. Treat them as something to ask about, not as absent.

Counts come from the NHTSA complaint and recall database — free, public, and worth checking yourself.

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 (estimate): $0 under extended coverage, $2,500-$5,000 without

Source: NHTSA complaints filed under electrics and electronics (304), the engine (36).

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 (estimate): $200-$400 plus the ICCU repair

Source: NHTSA complaints filed under electrics and electronics (304).

Rear window wiper absence and visibilityLow

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

Repair cost: Not yet priced

Source: NHTSA complaints filed under the brakes (23).

Cold-weather preconditioning on early softwareMedium

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

Repair cost (estimate): $0 OTA or dealer

Source: NHTSA complaints filed under electrics and electronics (304).
