2018 Acura RDX problems: engine and transmission complaints and recalls
46% of relevant owner complaints filed with NHTSA on the 2018 Acura RDX are about the engine, transmission or fuel system. That is a model-level pattern, not bad luck.
Worse than 59% of the 1,790 model years we track (2010–2023).
Excludes 6 airbag, lighting and seat-belt recall complaints that would otherwise mask the signal (unadjusted: 43%).
Does the 2018 Acura RDX have fuel system problems?
Owner complaints say yes, as a model-year pattern. 33 of 71 relevant complaints filed with NHTSA about the 2018 Acura RDX concern the engine, transmission or fuel system (46%), and the largest group is filed under fuel/propulsion system (17). For comparison, the 2017 scores 47% and the 2019 scores 29%. On a test drive, check for hard starts, stalling, hesitation, a fuel smell 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 Acura RDX?
That depends on the car in front of you, not just the model year. The 2018 Acura RDX has an elevated fuel system complaint pattern, so treat it as a car that needs proof: service records showing fuel system work, a cold-start test drive, and an independent pre-purchase inspection focused on the fuel system. A well-kept or already-repaired example can be a fine car; an unknown one is a gamble.
