Common Issues With The 2020-2022 Mazda Mazda6

The Mazda6 is a midsize sedan that stands out for its sleek, modern design and sporty driving dynamics. The 2020-2022 generation builds on Mazda’s reputation for engaging handling, premium interior materials, and advanced safety features. With both naturally aspirated and turbocharged engine options available (depending on the trim), the Mazda6 aims to provide an excellent balance between performance, fuel economy, and refinement. It comes equipped with an 8-speed automatic transmission (with a manual option available in some markets on earlier models), and Mazda’s signature “Kodo” design language gives the sedan a distinctive, elegant look.

Common Mechanical Issues
