2018 Mazda CX-5 problems: engine and transmission complaints and recalls
93% of relevant owner complaints filed with NHTSA on the 2018 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 99% of the 1,790 model years we track (2010–2023).
Does the 2018 Mazda CX-5 have engine problems?
Owner complaints say yes, heavily, as a model-year pattern. 111 of 119 relevant complaints filed with NHTSA about the 2018 Mazda CX-5 concern the engine, transmission or fuel system (93%), and the largest group is filed under engine (96). For comparison, the 2017 scores 23% and the 2019 scores 59%. 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.

Should I buy a 2018 Mazda CX-5?
That depends on the car in front of you, not just the model year. The 2018 Mazda CX-5 has an elevated engine complaint pattern, so treat it as a car that needs proof: service records showing engine work, a cold-start test drive, and an independent pre-purchase inspection focused on the engine. A well-kept or already-repaired example can be a fine car; an unknown one is a gamble.
