Cost to keep
What it costs to own, by how long you keep it
Scheduled servicing only, from a brand-new Sportage Plug-In Hybrid 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 | $113 | $9 |
| 3 years | 36,000 mi | $789 | $22 |

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 Sportage Plug-In Hybrid is known for is HV 13.8 kWh battery degradation / module failure ($4,000-$7,000). It is a range, not a certainty - but it is the number to have in your head at the dealership.
Operator notes
AWD standard. EV-mode operation reduces engine run-time, so oil lasts longer (still change at least yearly). Regen braking makes brakes last very long. 6-speed automatic (not eCVT). Timing chain. HV/PHEV components 10yr/100k warranty.
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 phev Sportage Plug-In Hybrid retires around 150,000 miles. 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.
