Brand-wide Mazda Problem Patterns

2.2 Diesel Oil Dilution: Frequent DPF regenerations can dump diesel into the oil, leading to engine wear or even runaway.
MX-5 Rear Arch/Sill Rust: A classic Mazda issue that persists even into the NC generation if not undersealed.
SkyActiv-D Camshaft Wear: Early 2.2 diesels (2012-2014) had soft camshafts that would wear prematurely, throwing metal filings into the turbo.
Folding Mirror Motor Failure: A very common, annoying fault across almost the entire 2014-2020 Mazda range.
