Cost to keep
What it costs to own, by how long you keep it
Scheduled servicing only, from a brand-new RDX 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 | $220 | $18 |
| 3 years | 36,000 mi | $1,095 | $30 |
| 5 years | 60,000 mi | $2,250 | $38 |
| 7 years | 84,000 mi | $2,825 | $34 |
| 10 years | 120,000 mi | $4,570 | $38 |
| 15 years | 180,000 mi | $7,170 | $40 |
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.
Operator notes
Timing CHAIN. K20C 2.0T is good for 200k+ with care. Direct-injected turbo - shorten oil to ~5,000 mi in cold/short-trip use. SH-AWD needs rear-diff and transfer-case fluid service. Acura's bestseller; refreshed 2022 with minor updates since. Full-synthetic 0W-20.
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 RDX 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.
