Cost to keep
What it costs to own, by how long you keep it
Scheduled servicing only, from a brand-new Sorento 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 | $108 | $9 |
| 3 years | 36,000 mi | $756 | $21 |
| 5 years | 60,000 mi | $1,987 | $33 |
| 7 years | 84,000 mi | $2,378 | $28 |
| 10 years | 120,000 mi | $4,176 | $35 |
| 15 years | 180,000 mi | $6,163 | $34 |
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 Sorento is known for is 2.5T 8-speed wet DCT electric oil-pump failure / power loss from about 20,000 miles ($0 under recall, else $3,000-$5,000). It is a range, not a certainty - but it is the number to have in your head at the dealership.
Operator notes
MQ4 generation (2021+, facelift 2024). Base 2.5L NA uses an 8-speed torque-converter auto; 2.5T turbo uses an 8-speed WET dual-clutch (DCT) needing periodic fluid service. Timing chain. Coolant first 120k. Brake fluid every 2 yr. Current model year on sale.
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 gas Sorento retires around 95,000 miles - but the exit window opens earlier here: 2.5T 8-speed wet DCT electric oil-pump failure / power loss risk window ($0 under recall, else $3,000-$5,000) 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.
