Cost to keep
What it costs to own, by how long you keep it
Scheduled servicing only, from a brand-new Mirai 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 | $60 | $5 |
| 3 years | 36,000 mi | $570 | $16 |
| 5 years | 60,000 mi | $1,380 | $23 |
| 7 years | 84,000 mi | $1,580 | $19 |
| 10 years | 120,000 mi | $2,760 | $23 |
| 15 years | 180,000 mi | $4,140 | $23 |
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 Mirai is known for is Fuel-cell stack degradation/replacement ($10,000+). It is a range, not a certainty - but it is the number to have in your head at the dealership.
Operator notes
Fuel cell EV - NO oil changes ever. ~182 hp e-motor, ~402 mi H2 range, RWD. Regen braking so friction brakes last very long. FC stack + HV components covered 8yr/100k; Toyota historically bundles complimentary fuel and maintenance. Hydrogen fueling limited to ~54 CA stations; severe depreciation but very low routine service cost.
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 battery-electric Mirai retires around 150,000 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.
