Toyota Mirai maintenance: the schedule, the costs, the traps
A full-size luxury sedan (RWD) with a battery-electric powertrain. Below: the service intervals with real cost ranges, the repairs Mirai owners actually report, and when a fleet operator would sell. Same data Carlyle uses to score fleet buys.

Mileage ranges where these repairs typically show up. Buying above a window is not automatically a pass - it just needs to be priced in.

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
On fleet math, 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.
