Known repair windows
What Electrified G80 owners actually run into
Mileage ranges where these repairs typically show up. Buying above a window is not automatically a pass - it just needs to be priced in.
ICCU (Integrated Charging Control Unit) failure
high severity20,000-60,000 mi · $1,500-$4,000
Included in Hyundai/Genesis/Kia ICCU recall; stops charging the 12V battery, can lead to loss of drive power. Fuse + software fix under recall; full unit replacement costly out of warranty.
HV traction battery degradation/replacement
high severityAny mileage · $18,000-$30,000
87.2 kWh pack; gradual range loss normal. Covered by 10yr/100k battery warranty; full replacement rare but very expensive after.
12V auxiliary battery failure/drain
medium severityAny mileage · $200-$400
Common EV no-start item, often tied to ICCU under-charging; can immobilize the car.
Charge-port door actuator / infotainment (CCNC) glitches
low severity20,000-80,000 mi · $300-$1,500
Software freezes, ccNC screen/OTA bugs, sticky charge-door motor; often software or single-part fix.
Regen-brake caliper seizing / rotor corrosion
low severityAny mileage · $300-$700 per axle
Light friction-brake use from regen lets pads/rotors corrode; annual clean/lube recommended.
Cost to keep
What it costs to own, by how long you keep it
Scheduled servicing only, from a brand-new Electrified G80 at 12,000 miles a year. Insurance, fuel, tires and depreciation are yours to add - this is the part the shop charges you for.
| You keep it | Odometer | Servicing | Per month |
|---|---|---|---|
| 1 year | 12,000 mi | $65 | $5 |
| 3 years | 36,000 mi | $745 | $21 |
| 5 years | 60,000 mi | $1,490 | $25 |
| 7 years | 84,000 mi | $1,815 | $22 |
| 10 years | 120,000 mi | $3,305 | $28 |
| 15 years | 180,000 mi | $4,795 | $27 |
Per-month can dip as the horizon lengthens - a major service lands in one year and then averages out across all the months after it. The left column is what you actually spend.
Beyond the schedule, the first big-ticket item this Electrified G80 is known for is ICCU (Integrated Charging Control Unit) failure from about 20,000 miles ($1,500-$4,000). It is a range, not a certainty - but it is the number to have in your head at the dealership.
Operator notes
EV - no oil changes; scheduled service is tires, cabin filter, brake fluid and long-interval EV coolant. Regen braking extends pads/rotors to 70k-100k+ mi. 800V dual-motor AWD, ~365 hp; adaptive dampers (not air suspension). Korea-built; Genesis withdrew it from the US after the 2025 model year (poor sales, no federal tax credit) though a refreshed version continues globally for 2026.
When the smart money sells
Keeping it yourself, there is no cutoff - the table above runs to fifteen years. On fleet math, where a car has to keep earning, a battery-electric Electrified G80 retires around 150,000 miles - but the exit window opens earlier here: ICCU (Integrated Charging Control Unit) failure risk window ($1,500-$4,000) opens ~20,000 mi. Carlyle's garage tracks this per car, against your actual odometer.
Cost ranges are typical US independent-shop estimates and vary by region and condition. Modeling, not mechanic advice - always confirm against your car's service records.
