Reliable

Reliability, common problems and owner reviews for the Mazda CX-3 2.0 SkyActiv-G (petrol). Check this before you buy used.

The 2.0 SkyActiv-G is a refreshingly sensible modern petrol — high-compression but naturally aspirated (no turbo to fail) and chain-driven, genuinely reliable and frugal. It rewards correct fuel and clean oil because of the high compression, and very-high-mileage cars can show a little carbon, but there are no design vices. With optional AWD it's one of the safer small-crossover petrols; the lower-power version can feel modest loaded but the engine itself is dependable.

Front crank seal / valve cover oil weepsminor

SkyActiv-G engines weep oil from the front crank seal and valve cover gasket with age — slow, cosmetic at first, worth monitoring rather than fearing.
