Is the Kia Soul Reliable? Affordable Used Car Complete Guide
By Caropsy · July 12, 2026 · 5 min read
The Kia Soul is one of the most recognizable vehicles on the road — boxy, fun, and consistently affordable. It's a frequent recommendation on budget used car lists, and it's earned that position. But like most Kia products, there's a generation-by-generation reliability story worth knowing, and the Theta engine concern that affected other Kia models is worth checking on certain years.

Generally reliable — newer generations significantly betterStrong used buy in the right years at an affordable price point.
Best Kia Soul years to buy used
2017–2019 (2nd gen late)The 2.0L naturally aspirated engine from these years is the most reliable Soul powertrain. These late second-generation models avoided the worst of the early reliability complaints while remaining affordable on the used market. Good sweet spot for budget buyers.
2020–2023 (3rd gen)The redesigned Soul brought a more refined interior and improved powertrain options. Reliability data shows improvement over earlier generations. The base 2.0L is again the reliable pick over the turbocharged 1.6T option.
Years to approach carefully
2010–2013 (1st gen)First generation Souls have more complaints than later models — particularly around the automatic transmission and some electrical issues. At this age, general wear and maintenance history become major factors.
Any Soul with 1.6T turboThe turbocharged 1.6T engine has generated more complaints than the naturally aspirated 2.0L across multiple Kia models. Stick to the base engine for the most reliable used Soul experience.
Common Kia Soul problems
Transmission (1st gen automatic): More complaints than the manual on early models. The CVT on newer versions is better behaved than Nissan's equivalent.
Paint quality: Thinner than Honda or Toyota paint — more susceptible to chips and fading over time.
Infotainment (early models): UVO system is dated on older models. Not a mechanical issue but a daily annoyance.
💡 The Kia Soul's boxy design means less aerodynamic efficiency but more usable interior space than you'd expect from the price. Screenshot any listing and grade it on Caropsy to see what that specific year is known for.
Bottom line
A 2017–2019 or 2020+ Kia Soul with the 2.0L naturally aspirated engine is a genuinely solid affordable used car buy. Distinctive, practical, and reasonably reliable. Avoid the first generation and the turbocharged engine option across all years.
