2020 Kia Soul problems: engine and transmission complaints and recalls

VERY HIGH COMPLAINT SIGNAL
82%
304 of 369 relevant owner complaints are about the engine, transmission or fuel system

82% of relevant owner complaints filed with NHTSA on the 2020 Kia Soul 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 98% of the 1,790 model years we track (2010–2023).

Excludes 12 airbag, lighting and seat-belt recall complaints that would otherwise mask the signal (unadjusted: 80%).

NHTSA data checked October 3, 2026

The VIN is on the listing, the driver’s door jamb, and the bottom of the windshield on the driver’s side.

Does the 2020 Kia Soul have engine problems?

Owner complaints say yes, heavily, as a model-year pattern. 304 of 369 relevant complaints filed with NHTSA about the 2020 Kia Soul concern the engine, transmission or fuel system (82%), and the largest group is filed under engine (238). For comparison, the 2019 scores 76% and the 2021 scores 86%. 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.

engine21V259000 · Apr 2021

Kia Motors America (Kia) is recalling certain 2020-2021 Soul, and 2021 Seltos vehicles equipped with 2.0L Nu MPI engines. The piston oil rings may not have been properly heat-treated, which may result in engine damage.

Risk: A damaged engine may stall, increasing the risk of a crash. In addition, oil may leak onto hot exhaust components, increasing the risk of a fire.

Fix: Kia will notify owners, and dealers will inspect and, if necessary, replace the engine, free of charge. In addition, Kia will deploy Piston Ring Noise Sensing System (PNSS) software. The recall began June 11, 2021.…
