2018 Kia Sportage problems: engine and transmission complaints and recalls

VERY HIGH COMPLAINT SIGNAL
65%
104 of 164 relevant owner complaints are about the engine, transmission or fuel system

65% of relevant owner complaints filed with NHTSA on the 2018 Kia Sportage 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 87% of the 1,790 model years we track (2010–2023).

NHTSA data checked October 3, 2026

The VIN is on the listing, the driver’s door jamb, and the bottom of the windshield on the driver’s side.

Does the 2018 Kia Sportage have engine problems?

Owner complaints say yes, heavily, as a model-year pattern. 104 of 164 relevant complaints filed with NHTSA about the 2018 Kia Sportage concern the engine, transmission or fuel system (65%), and the largest group is filed under engine (91). For comparison, the 2017 scores 67% and the 2019 scores 66%. 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.
