2018 Hyundai Santa Fe problems: engine and transmission complaints and recalls
69% of relevant owner complaints filed with NHTSA on the 2018 Hyundai Santa Fe 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 91% of the 1,790 model years we track (2010–2023).
Excludes 23 airbag, lighting and seat-belt recall complaints that would otherwise mask the signal (unadjusted: 65%).
Does the 2018 Hyundai Santa Fe have engine problems?
Owner complaints say yes, heavily, as a model-year pattern. 279 of 407 relevant complaints filed with NHTSA about the 2018 Hyundai Santa Fe concern the engine, transmission or fuel system (69%), and the largest group is filed under engine (250). For comparison, the 2017 scores 78% and the 2019 scores 49%. 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.
