What Expedition owners actually run into

Cost to keep
What it costs to own, by how long you keep it
Scheduled servicing only, from a brand-new Expedition 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 | $150 | $13 |
| 3 years | 36,000 mi | $640 | $18 |
| 5 years | 60,000 mi | $1,600 | $27 |
| 7 years | 84,000 mi | $1,960 | $23 |
| 10 years | 120,000 mi | $3,990 | $33 |
| 15 years | 180,000 mi | $5,590 | $31 |
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 Expedition is known for is Cam phaser rattle (3.5L EcoBoost) from about 80,000 miles ($1,800-$3,000). It is a range, not a certainty - but it is the number to have in your head at the dealership.
Operator notes
Fully redesigned 5th-gen (2025); timing CHAIN not belt; synthetic-blend oil to 10k per IOLM; EcoBoost plugs ~60k; severe service (towing/dusty) halves intervals. New platform so high-mileage failures projected from proven 3.5 EcoBoost history.
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 Expedition 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.
