Known repair windows
What Kona EV 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.

Cost to keep
What it costs to own, by how long you keep it
Scheduled servicing only, from a brand-new Kona EV 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 | $75 | $6 |
| 3 years | 36,000 mi | $420 | $12 |
| 5 years | 60,000 mi | $885 | $15 |
| 7 years | 84,000 mi | $1,135 | $14 |
| 10 years | 120,000 mi | $1,820 | $15 |
| 15 years | 180,000 mi | $2,705 | $15 |
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 Kona EV is known for is Onboard charger (OBC) / charge-port fault from about 20,000 miles ($1,500-$3,500). 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. Single-motor FWD on 400V architecture (not the 800V E-GMP). Regen braking greatly extends friction-brake life; still flush brake fluid. Battery warranty 10yr/100,000 mi. Officially the Kona Electric.
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 Kona EV retires around 150,000 miles - but the exit window opens earlier here: HV battery (48.6 / 64.8 kWh) degradation risk window ($10,000-$16,000) opens ~100,000 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.
