Mazda CX-3 I (DK) (2015 – 2023)

Reliability score : 8.8/10

The first-generation Mazda CX-3 (DK) is an urban SUV (B-segment) based on the Mazda 2 city car platform. Launched in 2015, it stands out with its dynamic (Kodo) design, meticulous finish bordering on premium, and excellent road handling. Contrary to the downsizing trend, Mazda opted for rightsizing with large, highly reliable naturally aspirated gasoline engines (Skyactiv-G). It received a major facelift in 2018 (improved sound insulation, electric parking brake, new grille, replacement of the 1.5 Diesel with a 1.8 Diesel). Although it left the European and North American markets at the end of 2021 in favor of the CX-30, its production continued until 2023 for other markets (Japan, Australia). It is a benchmark choice on the used market for its gasoline reliability, although its interior s

✅ Strengths

Exceptional reliability of gasoline engines (Skyactiv-G)
Very smooth and robust torque converter automatic gearbox (Skyactiv-Drive)
Dynamic and precise road handling (typical Mazda)
Interior finish quality and control ergonomics
Exterior design that ages very well
Availability of genuine all-wheel drive (AWD)

⚠️ Weaknesses

Very restricted rear passenger space (legroom and headroom)
Small trunk volume for the category (350 liters, or even 287L with the Bose subwoofer)
Imperfect sound insulation on models before the 2018 facelift
Problematic reliability of the 1.5 Diesel engine
Somewhat firm suspension at low speeds (especially with 18-inch wheels)

🎯 Verdict

The Mazda CX-3 is an excellent used car choice, provided you exclusively target gasoline engines (Skyactiv-G). The 2.0L naturally aspirated engine is a model of reliability in an industry dominated by fragile small turbo engines. It's an ideal vehicle for a couple or a single person looking for a dynamic, well-finished small SUV with no major mechanical issues. However, you should avoid the 1.5 Diesel (too many DPF and oil dilution problems) and accept its practical drawbacks: a small trunk and cramped rear seats. Opt for a post-2018 (facelift) model for better acoustic comfort.
