Cost to keep
What it costs to own, by how long you keep it
Scheduled servicing only, from a brand-new Crown Signia at 12,000 miles a year. Insurance, fuel, tires and depreciation are yours to add - this is the part the shop charges you for.

| 1 year | 12,000 mi | $110 | $9 |
| 3 years | 36,000 mi | $530 | $15 |

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 Crown Signia is known for is HV traction battery aging ($1,800-3,500). It is a range, not a certainty - but it is the number to have in your head at the dealership.
Operator notes
Timing chain. 2.5L 4th-gen hybrid (0W-16, eCVT, ~240 hp AWD). First model year 2025 - limited long-term history. Uses older 4th-gen hybrid (noisier/coarser under load than 5th-gen Camry/Prius). Regen brakes last long.
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 hybrid Crown Signia 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.
