Frequently asked questions
Which Mazda CX-3 engine is the most reliable?
2.0 SkyActiv-G (petrol) — Reliable verdict. 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.
