Mazda CX-5 (KF) Common Problems & Reliability
The second-generation Mazda CX-5 (KF), launched in 2017, is a sophisticated and premium-feeling SUV that successfully bridges the gap between mainstream and luxury segments. Positioned as a direct rival to the Volkswagen Tiguan and BMW X1, it is widely praised in the UK for its sleek "Kodo" design, high-quality interior materials, and a driving experience that remains one of the most engaging in its class. Unlike many rivals that moved to small turbocharged engines, Mazda utilized their "Skyactiv" philosophy, employing larger, naturally aspirated petrol engines and highly efficient diesels. Reliability is a highlight for petrol-powered CX-5s, with the 2.0-litre and 2.5-litre Skyactiv-G units proving to be exceptionally durable and low-maintenance. However, the 2.2-litre Skyactiv-D diesel engine requires more caution; while refined, it is prone to DPF blockages and oil dilution if used primarily for short urban trips, which can lead to expensive internal carbon buildup over time. Other common owner complaints across the range include "ghost touches" on the infotainment screen, failing power-folding mirror motors, and front brake rotors that can warp prematurely, leading to steering wheel wobble under braking. When buying a used KF-generation CX-5 in the UK, the 2.0-litre petrol manual is often considered the most trouble-free choice for those who don't cover high annual mileages. Prospective owners should carefully test the infotainment system and folding mirrors for smooth operation and check the service history for oil changes every 10,000 miles, which is critical for the longevity of the diesel variants. A full Mazda or specialist service history is highly desirable, ensuring that the latest software updates for the various driver-assist systems have been applied.
