2018 Acura MDX problems: engine and transmission complaints and recalls
50% of relevant owner complaints filed with NHTSA on the 2018 Acura MDX are about the engine, transmission or fuel system. That is a model-level pattern, not bad luck.
Worse than 65% of the 1,790 model years we track (2010–2023).
Does the 2018 Acura MDX have engine problems?
Owner complaints say yes, as a model-year pattern. 81 of 168 relevant complaints filed with NHTSA about the 2018 Acura MDX concern the engine, transmission or fuel system (50%), and the largest group is filed under engine (35). For comparison, the 2017 scores 64% and the 2019 scores 55%. 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.
