The third-generation Mazda 6 (chassis code GJ, then GL after the 2015 facelift) was launched in 2012, marking a stylistic and technological turning point for the brand. Adopting the 'Kodo – Soul of Motion' design language and integrating the suite of Skyactiv technologies (engines, transmissions, chassis), it positions itself as an elegant and dynamic family sedan, offering a serious alternative to German and French benchmarks. It benefited from two major facelifts: the first in 2015 (GL) with interior improvements, enhanced sound insulation, and the introduction of G-Vectoring Control (GVC); the second in 2018, bringing a more significant front-end redesign, an even more refined interior, and the introduction of the 2.5 Skyactiv-G Turbo engine in certain markets. Overall, the Mazda 6 GJ/G
The third-generation Mazda 6 is an excellent family sedan, offering a rare blend of style, driving pleasure, and reliability, especially with its Skyactiv-G gasoline engines. For a confident and recommended purchase: Prioritize gasoline versions (2.0L or 2.5L Skyactiv-G). They are remarkably reliable, economical to maintain, and offer undeniable driving pleasure. The 2.5L Turbo is an excellent choice for those seeking more power without sacrificing reliability. For a purchase to negotiate or with caution: The 2.2 Skyactiv-D diesel models from the early years (2012-2015) should be considered with the utmost caution. It is imperative to verify that recalls concerning the timing chain and injector seals have been carried out and that the service history is impeccable. Post-2016 diesel models are more reliable but still require appropriate use (long journeys) to avoid DPF and clogging issues. Overall, the Mazda 6 GJ/GL is a wise choice for anyone looking for a reliable, well-finished, and pleasant-to-live-with sedan, provided the engine is chosen carefully and the history is verified.
