2016 Kia Optima problems: engine and transmission complaints and recalls
70% of relevant owner complaints filed with NHTSA on the 2016 Kia Optima 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 92% of the 1,790 model years we track (2010–2023).
Excludes 58 airbag, lighting and seat-belt recall complaints that would otherwise mask the signal (unadjusted: 65%).
Does the 2016 Kia Optima have engine problems?
Owner complaints say yes, heavily, as a model-year pattern. 490 of 698 relevant complaints filed with NHTSA about the 2016 Kia Optima concern the engine, transmission or fuel system (70%), and the largest group is filed under engine (425). For comparison, the 2015 scores 69% and the 2017 scores 78%. 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.

Should I buy a 2016 Kia Optima?
That depends on the car in front of you, not just the model year. The 2016 Kia Optima has an elevated engine complaint pattern, so treat it as a car that needs proof: service records showing engine work, a cold-start test drive, and an independent pre-purchase inspection focused on the engine. A well-kept or already-repaired example can be a fine car; an unknown one is a gamble.
