The third-generation Mazda3 (BM series from 2013-2016, and BN facelift from 2016-2019) marked a significant turning point for the brand. It fully integrated the 'Kodo - Soul of Motion' design language and the complete suite of SkyActiv technologies (chassis, engines, and transmissions). Praised for its exceptional driving dynamics, precise steering, and premium-feeling interior (especially post-facelift), it stands out as one of the most engaging cars in the compact segment. However, there is a stark contrast in reliability depending on the powertrain. While the naturally aspirated SkyActiv-G petrol engines are considered virtually bulletproof, the SkyActiv-D diesel engines (the primary focus of this report) suffer from severe, well-documented design flaws. Buyers looking at the diesel var
The 3rd Generation Mazda3 is a tale of two cars. If you are buying a petrol (SkyActiv-G), it is an absolute triumph—reliable, engaging, and beautiful. However, since the focus here is on the diesel (SkyActiv-D), the verdict is drastically different. The 2.2D is a high-risk engine plagued by catastrophic camshaft, vacuum pump, and oil dilution issues. It should be avoided unless it has a meticulously documented history, has had the camshafts replaced with the revised parts, and will be used exclusively for long highway runs. The 1.5D is safer but still suffers from heavy carbon buildup. If you must buy a Mazda3, do yourself a favor and buy the petrol version.
