Known repair windows
What CT4-V owners actually run into
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
V (2.7T ~325 hp) and V-Blackwing (472-hp 3.6L twin-turbo, 6-speed manual or 10-speed auto). Discontinued after 2026 with CT4. Timing-chain. Performance use shortens brake-fluid/diff-fluid intervals; track owners flush brake fluid each event.
When the smart money sells
On fleet math, a gas CT4-V retires around 95,000 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.
