Cadillac ATS-V maintenance: the schedule, the costs, the traps
A compact high-performance sports coupe (sedan ended 2018) with a gas powertrain. Below: the service intervals with real cost ranges, the repairs ATS-V owners actually report, and when a fleet operator would sell. Same data Carlyle uses to score fleet buys.
Service schedule
What it needs, and what that runs

Known repair windows
What ATS-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.
3.6L TT (LF4) charge-air cooler heat-soak / coolant lines
medium severity30,000-80,000 mi · $500-$1,200
Twin-turbo intercooler heat soak; coolant line seepage under hard use
GDI intake carbon buildup

Rear differential / driveline clunk
medium severity40,000-90,000 mi · $600-$1,500

Clutch wear (6-speed manual, track use)
medium severity30,000-70,000 mi · $2,000-$3,500

Operator notes
464-hp 3.6L twin-turbo LF4; 6-speed manual or 8-speed auto. Timing-chain. High-performance = shorter brake-fluid and diff-fluid intervals; track owners flush brake fluid each event. Was replaced by CT4-V.
When the smart money sells
On fleet math, a gas ATS-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.
