What Navigator 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 Navigator 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 | $165 | $14 |
| 3 years | 36,000 mi | $945 | $26 |
| 5 years | 60,000 mi | $3,240 | $54 |
| 7 years | 84,000 mi | $4,020 | $48 |
| 10 years | 120,000 mi | $7,630 | $64 |
| 15 years | 180,000 mi | $10,870 | $60 |
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 Navigator is known for is 3.5L EcoBoost cam-phaser cold-start rattle from about 60,000 miles ($1,500-$3,500). It is a range, not a certainty - but it is the number to have in your head at the dealership.
Operator notes
Timing CHAIN. Current model (2026 in production; all-new 5th gen since 2025 with 48-inch panoramic display). Powertrain: 3.5L twin-turbo EcoBoost V6 (~440 hp) + 10-speed 10R80, RWD/4WD, air suspension standard. Full-synthetic oil 10k normal / 5k severe (towing = severe). Air suspension and 3.5EB cam phasers are the defining big-ticket risks on the platform.
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 Navigator retires around 95,000 miles - but the exit window opens earlier here: 3.5L EcoBoost cam-phaser cold-start rattle risk window ($1,500-$3,500) opens ~60,000 mi. 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.
