Mazda CX-9 II (TC) (2016 – 2023)

Reliability score : 8.8/10

The second-generation Mazda CX-9 (codename TC) marks the Japanese manufacturer's move upmarket in the large 3-row family SUV segment. Abandoning the Ford-sourced V6 of the previous generation, this model introduces the 2.5-liter 4-cylinder Turbo SKYACTIV-G engine, designed to offer the torque of a V6 with better efficiency. Primarily intended for the North American, Australian, and Middle Eastern markets (very rare in Western Europe), the CX-9 stands out with its elegant Kodo design, an interior finish quality that flirts with the premium segment, and driving dynamics that are above average for its class. It achieves excellent overall reliability ratings.

✅ Strengths

Manufacturing and finish quality above the Japanese average (close to premium)
Excellent overall reliability (recommended by ADAC and J.D. Power)
Robust 2.5T SKYACTIV-G engine with a perfectly integrated turbo
Smooth and extremely reliable 6-speed automatic gearbox (SKYACTIV-Drive)
High-performing and trouble-free all-wheel drive (i-ACTIV AWD)
Generous onboard space with 3 real rows of seats

⚠️ Weaknesses

Slight oil consumption inherent to the 2.5T design (to be monitored)
Lack of mechanical alternatives (no hybrid, no diesel)
Aging infotainment system (Mazda Connect) on early model years (2016-2019)
Trunk volume slightly lower than some direct competitors (e.g., Chevrolet Traverse or Honda Pilot)

🎯 Verdict

The second-generation Mazda CX-9 (TC) is an excellent choice for families looking for a large 3-row SUV combining reliability, driving dynamics, and a premium finish. Unlike many of its competitors that have suffered from transmission issues or complex V6 engines, the CX-9 relies on a 2.5 Turbo 4-cylinder and a 6-speed automatic gearbox whose robustness is now widely proven (highly rated by ADAC, TÜV Report, and What Car?). The only regular mechanical point of attention concerns slight oil consumption, normal for this block, which requires a simple periodic check. If the official recalls (notably the fuel pump on 2018-2019 models) have been performed, it is a vehicle that offers peace of mind well above the average for its segment.
