Editor's note

The second-generation Soul (2014–2019) carries the Gamma and Nu engines that were subject to Kia's engine-failure investigation and the 2019 recall for catalytic-converter damage leading to piston failure; the 2014–2016 years have the highest counts, with engine noise, stalling and fire cited. The 2017–2019 years are better, and the third generation from 2020 is quiet apart from a bump in 2020. Read the full note on the model page. 2018 specifically: a year the record favours — 218 complaints, score 83/100. The caveats in the note apply to other years of this nameplate more than to this one.
