Cost to keep
What it costs to own, by how long you keep it
Scheduled servicing only, from a brand-new NX 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 | $215 | $18 |
| 3 years | 36,000 mi | $1,040 | $29 |
| 5 years | 60,000 mi | $2,515 | $42 |
| 7 years | 84,000 mi | $2,945 | $35 |
| 10 years | 120,000 mi | $5,730 | $48 |
| 15 years | 180,000 mi | $8,245 | $46 |
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 NX is known for is Turbocharger wear/PCV (NX 350 2.4L turbo) ($2,000-$4,000). It is a range, not a certainty - but it is the number to have in your head at the dealership.

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 NX retires around 95,000 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.
