Mazda Mazda2 I (DY) (2002 – 2007)

Reliability score : 7.2/10

The first-generation Mazda2 (code DY), launched in Europe from 2003 (2002 in Japan as the Mazda Demio), marked a turning point for the manufacturer. Based on the B3 platform jointly developed with Ford (shared with the Ford Fiesta Mk5 and Ford Fusion), it adopted a very cubic urban mini-MPV silhouette, prioritizing interior space and modularity. A facelift occurred in 2005, bringing new headlights, redesigned bumpers, and improved interior materials. While the gasoline engines are Ford/Mazda originals and known to be very robust, the diesel version (1.4 MZ-CD) comes from the PSA/Ford partnership (DV4 / DLD-414 engine). This model is generally reliable, but its advanced age and the sensitivity of its diesel engine require great vigilance when purchasing.

✅ Strengths

⚠️ Weaknesses

🎯 Verdict

The first-generation Mazda2 is an excellent versatile city car, provided you choose the right engine. The verdict is clear: prioritize the gasoline versions (1.25, 1.4 or 1.6 MZI) which offer remarkable peace of mind, despite slightly higher fuel consumption. The 1.4 MZ-CD diesel version is to be avoided, unless you have invoices proving recent replacement of the injector seals and rigorous maintenance. In any case, a thorough inspection for rust on the underbody is mandatory before purchase, as this defect is the main enemy of this generation.
