Mazda CX-3 I (DK) (2015 – 2023)

Reliability score : 8.8/10

The Mazda CX-3 (Generation I - DK) is a subcompact crossover SUV based on the Mazda2 (DJ) platform. Introduced in 2015, it stands out in the crowded B-SUV segment thanks to its striking 'Kodo' design language, premium interior materials, and engaging driving dynamics. Unlike many competitors that rely on small-displacement turbocharged engines, Mazda opted for its 'right-sizing' philosophy, equipping the CX-3 primarily with naturally aspirated 2.0L Skyactiv-G petrol engines. The model received a mild facelift in 2018 (improving NVH levels, adding an electronic parking brake, and updating the diesel engine) and another minor update in 2020. While it excels in reliability (especially the petrol variants) and driving pleasure, it is heavily compromised by its tight rear passenger space and a

✅ Strengths

Exceptional reliability of the Skyactiv-G petrol engines (no turbochargers to fail)
Traditional 6-speed torque-converter automatic transmission (smooth and much more reliable than competitors' CVTs or dual-clutches)
Engaging driving dynamics with precise steering and excellent chassis control
High-quality interior materials and premium feel for the B-SUV segment
Available with a very capable i-Activ AWD system

⚠️ Weaknesses

Very cramped rear seats (legroom and headroom are severely lacking)
Small boot capacity (350 liters, reduced further if equipped with Bose subwoofer)
Thin paint quality (highly susceptible to stone chips and scratches)
High NVH (Noise, Vibration, Harshness) levels at highway speeds on pre-2018 models
Diesel engines (Skyactiv-D) are problematic if used in urban environments

🎯 Verdict

The Mazda CX-3 is an outstanding choice in the subcompact crossover segment if you choose a petrol engine (Skyactiv-G). The 2.0L naturally aspirated engine is a masterpiece of longevity, offering a refreshing alternative to the complex, small-displacement turbo engines found in European rivals. It is highly recommended to pair it with the excellent 6-speed automatic transmission. However, avoid the diesel variants (Skyactiv-D) unless your daily commute consists entirely of long highway journeys, as they are plagued by DPF and oil dilution issues. Buyers must also accept the CX-3's main compromises: it is essentially a lifted Mazda2, meaning rear passenger space and cargo capacity are very limited. If you treat it as a stylish, elevated coupe for two, it is a brilliant and trouble-free purchase.
