Cost to keep
What it costs to own, by how long you keep it
Scheduled servicing only, from a brand-new TLX 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 | $4,595 | $38 |
| 15 years | 180,000 mi | $7,220 | $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.
Beyond the schedule, the first big-ticket item this TLX is known for is Type S 3.0L turbo V6 turbo/wastegate & cooling from about 60,000 miles ($1,500-$3,000). It is a range, not a certainty - but it is the number to have in your head at the dealership.
Operator notes
Timing CHAIN. Base = 2.0T K20C + 10AT; Type S = 3.0L turbo V6 + 10AT + SH-AWD. Direct-injected turbos - shorten oil to ~5,000 mi in cold/short-trip use. SH-AWD needs rear-diff/transfer-case service. 2nd gen (2021-2025); DISCONTINUED after MY2025 as Acura shifts to SUVs/EVs.
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 TLX 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.
