2021 Mazda CX-5 problems: engine and transmission complaints and recalls
63% of relevant owner complaints filed with NHTSA on the 2021 Mazda CX-5 are about the engine, transmission or fuel system. Well over half of everything owners reported is the drivetrain. That is a severe model-level pattern; every model year we track at this level has a documented failure behind it.
Worse than 85% of the 1,790 model years we track (2010–2023).
Excludes 5 airbag, lighting and seat-belt recall complaints that would otherwise mask the signal (unadjusted: 61%).
Does the 2021 Mazda CX-5 have engine problems?
Owner complaints say yes, heavily, as a model-year pattern. 90 of 142 relevant complaints filed with NHTSA about the 2021 Mazda CX-5 concern the engine, transmission or fuel system (63%), and the largest group is filed under engine (80). For comparison, the 2020 scores 27% and the 2022 scores 39%. On a test drive, check for stalling, loss of power, rough idle, oil consumption or a check-engine light. This describes the model year, not any one car: a well-maintained or already-repaired example can be fine, and a clean model year can still have a bad car in it.
