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
On fleet math, 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.
