Mazda Mazda3 III (BM) (2013 – 2019)

Reliability score : 8.4/10

The third-generation Mazda3 (chassis code BM for 2013-2016, and BN for the 2016-2019 facelift) represents a major turning point for the brand. It fully integrated the 'Kodo - Soul of Motion' design language and the complete suite of 'Skyactiv' technologies (engines, transmissions, chassis, and body). Available as a 5-door hatchback and a 4-door fastback (sedan), it is widely regarded as one of the best-driving cars in the compact class. The 2016 'BN' facelift introduced G-Vectoring Control (GVC) for improved handling, better sound insulation, and interior material upgrades. While its naturally aspirated petrol engines are celebrated for their bulletproof reliability and real-world efficiency, the diesel variants have a much more troubled history. Overall rating: Excellent for petrol models

✅ Strengths

Exceptional reliability of Skyactiv-G petrol engines
Class-leading driving dynamics, precise steering, and excellent chassis balance
Smooth and reliable 6-speed torque-converter automatic transmission (no problematic CVTs or DCTs)
High-quality interior materials, especially on the BN facelift (2016+)
Ergonomic infotainment system with a physical rotary controller (safer while driving)
Timeless exterior design (Kodo)

⚠️ Weaknesses

Skyactiv-D 2.2 diesel engine is plagued with expensive mechanical issues on early models
Thin, fragile paint (Soul Red is particularly prone to stone chips)
Road and wind noise is higher than average (partially fixed in the 2016 facelift)
Rear passenger space and boot capacity are slightly below class average
'Ghost touch' issue on the infotainment screen is very common

🎯 Verdict

The Mazda3 (BM/BN) is one of the smartest used-car purchases in the compact segment—provided you choose the right engine. If you opt for a Skyactiv-G petrol model, you are getting a highly reliable, engaging, and stylish car that will easily surpass 250,000 km with basic maintenance. The 2.0L petrol is the absolute sweet spot. However, the Skyactiv-D diesels should be approached with extreme caution, or avoided entirely if it's an early 2.2L model (2013-2015), due to severe and expensive engine flaws. Try to stretch your budget for a post-2016 'BN' facelift model to benefit from improved sound insulation and better ride quality.
