2020 Kia Optima: True Cost, Problems & Verdict
145 NHTSA owner complaints · 0 recalls · data-computed verdict. No opinions — public data only.
Editor's note
The Optima shares the Sonata's Theta II engines and the same recall history, and its 2013 and 2015 model years carry the highest counts — engine knocking, stalling and fire risk, addressed by the 2017 recall and the extended engine warranty. From 2017 the Optima improves sharply, and the 2018–2020 cars score around 90. Read the full note on the model page. 2020 specifically: a year the record favours — 145 complaints, score 91/100. The caveats in the note apply to other years of this nameplate more than to this one.
