The larger-displacement option on this Mazda3 generation — the same Skyactiv-G engine family covered on the standard 2.0L page, simply bored out for more low-end torque on higher trims.
The Mazda3's light, well-balanced body suits this larger-displacement engine just as well as the standard 2.0L — genuinely stronger low-end torque that's especially welcome in the automatic-equipped cars on this trim level.
This is the same Skyactiv-G engine family covered on the standard Mazda3 page, simply at the larger of its two common displacements — the reliability profile carries over directly, not a separate consideration.
This is about the car itself — for engine-specific failure points, see the dedicated engine page below.
This Mazda3 is a defining application of the larger-displacement Skyactiv-G. Full detail on this engine family's strong reliability track record lives on the dedicated engine page.

Ask about fuel quality history, since this engine's high-compression design is somewhat less forgiving of consistently low-octane fuel.
Check clutch engagement and shift quality on manual examples, a normal wear item rather than a specific defect to worry about.
