⚠️ Weaknesses

🎯 Verdict

The second-generation Mazda CX-5 is an excellent choice in the used car market, offering a rare blend of driving pleasure, perceived quality, and reliability. For versatile or urban/road use, the Skyactiv-G gasoline engines (2.0 and 2.5) are to be preferred. They are exemplarily robust, suffer from no known major defects, and offer great peace of mind. Their fuel consumption is reasonable for naturally aspirated engines, but don't expect miracles in the city. For high-mileage drivers primarily undertaking long highway journeys, the 2.2 Skyactiv-D diesel can be an interesting option for its fuel efficiency and torque. However, it requires increased vigilance regarding maintenance: very regular oil changes with the specific oil and ensuring the vehicle is used on routes that allow for complete DPF regenerations. An impeccable service history is non-negotiable for this engine. The 2022 facelift brought notable improvements in terms of infotainment and comfort, making post-2021 models slightly more desirable, but earlier versions remain very good buys. Overall, the CX-5 is a vehicle to BUY with confidence if maintenance has been followed, especially for gasoline versions.
