2018 Kia Sedona problems: engine and transmission complaints and recalls
56% of relevant owner complaints filed with NHTSA on the 2018 Kia Sedona are about the engine, transmission or fuel system. That is a model-level pattern, not bad luck.
Worse than 75% of the 1,790 model years we track (2010–2023).
Excludes 9 airbag, lighting and seat-belt recall complaints that would otherwise mask the signal (unadjusted: 46%).
Does the 2018 Kia Sedona have engine problems?
Owner complaints say yes, as a model-year pattern. 22 of 39 relevant complaints filed with NHTSA about the 2018 Kia Sedona concern the engine, transmission or fuel system (56%), and the largest group is filed under engine (21). For comparison, the 2017 scores 57% and the 2019 scores 39%. 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.

2018 Kia Sedona engine and transmission recalls
No engine or transmission recalls. NHTSA lists 3 recall campaigns on the 2018 Kia Sedona, none of them for the engine, transmission or fuel system.

The owner complaints above are a separate record and often point at problems that never became a recall.
