Kestrel Take
The enthusiast's midsize sedan and one of the least troublesome cars in this whole guide. Skyactiv is a conventional port-and-direct-injected engine with a conventional automatic — no CVT, no dual clutch, no turbo. The main enemy is rust in salt states.
Known Issues for the 2016 Mazda Mazda6
Ranked by wallet impact. These are documented, recurring problems — not freak accidents.
