Cost to keep
What it costs to own, by how long you keep it
Scheduled servicing only, from a brand-new Grand Highlander 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 | $120 | $10 |
| 3 years | 36,000 mi | $565 | $16 |
| 5 years | 60,000 mi | $1,215 | $20 |
| 7 years | 84,000 mi | $1,515 | $18 |

| 15 years | 180,000 mi | $3,965 | $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 Grand Highlander is known for is Turbo (2.4T / Hybrid MAX) long-term wear from about 80,000 miles ($1,500-2,500). 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 2.4L turbo (265 hp, 8AT); also 2.5L hybrid and 2.4T Hybrid MAX (362 hp) offered. Turbo needs 0W-20 at 5k severe / 10k normal. New for 2024 - limited long-term data, three early NHTSA recalls. Hybrid variants add HV battery aging; regen brakes last longer.
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 Grand Highlander 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.
