The 2020 Soul is a sensible, cheap, low-risk used car — but two things are worth getting straight, because the internet panic about Kia engines doesn’t apply here the way people assume.
It’s not the Theta
The non-turbo 2020 Soul runs the 2.0L Nu engine. That is not the Theta II that put Kia near the top of our worst-platforms list. The Nu is a plain, durable engine with no rod-bearing or fire history. The Soul is not on our list anywhere. Trim (X-Line, etc.) is cosmetic and changes nothing mechanical.
The 2020 shows a slightly elevated complaint count (~340) only because it’s the first year of the third-gen redesign — mostly minor electronics/infotainment teething. It settles fast (2021: ~200, 2022: ~82).
The real watch item: the IVT
The 2020 Soul’s automatic is Kia’s IVT — a CVT-type transmission. It’s been more reliable than the Jatco CVT that sits at number ten on our list, but it’s still a CVT, and dealers will tell you the fluid is “lifetime.” It isn’t. That’s how CVTs die.
- Service the IVT fluid on a real schedule (drain-and-fill, correct Kia spec)
- On the test drive, confirm no shudder/hesitation pulling away from a stop
- Trans-fluid service records are the green flag
Should you buy one?
Yes — engine’s a non-issue, the first-year bump is minor, just respect the CVT and don’t believe the “sealed for life” line. A 2020 Soul non-turbo with documented IVT service is a genuinely sensible, low-cost used car. On a vehicle this cheap to run, the warranty calculator will often say skip — and that’s the honest answer.
