A compact SUV with a gas powertrain. Below: the service intervals with real cost ranges, the repairs CX-50 owners actually report, and when a fleet operator would sell. Same data Carlyle uses to score fleet buys.

Operator notes
Current (introduced 2023), still sold. Rugged/outdoorsy sibling of the CX-30 on the larger CX-5 platform. Offered with 2.5L Skyactiv-G NA and 2.5L Turbo; timing CHAINS. Post-June-2020 builds have the revised cylinder head (avoids the early-2.5 cracking TSB). Normal = 7,500 mi/12 mo synthetic; severe ~5,000 mi. FL-22 coolant ~10 yr/120k.
When the smart money sells
On fleet math, a gas CX-50 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.
