Mazda CX-3 maintenance: the schedule, the costs, the traps
A subcompact crossover SUV with a gas powertrain. Below: the service intervals with real cost ranges, the repairs CX-3 owners actually report, and when a fleet operator would sell. Same data Carlyle uses to score fleet buys.

Known repair windows
What CX-3 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
Discontinued after 2021 in the US and globally (replaced by CX-30). 2.0L Skyactiv-G uses a timing CHAIN, no belt interval. Schedule 1 (normal) = 7,500 mi/12 mo synthetic oil; Schedule 2 (severe: short trips, dust, towing) shortens to ~5,000 mi. Mazda FL-22 long-life coolant first change ~10 yr/120k. Age-related items (rubber hoses, bushings, brakes) now dominate on used examples.
When the smart money sells
On fleet math, a gas CX-3 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.
