2020 Kia Soul: engine and transmission complaints

VERY HIGH COMPLAINT SIGNAL
82%
299 of 363 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 1,230 model years we track (2010–2023).

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

Manufacturers fix things mid-generation. A bad year next to a clean one is common; the fix usually arrived in between.

Other subcompact cars with no elevated signal in 2020

The percentage is each model year's drivetrain complaint share. No elevated signal describes the model year, not any one car; a well-kept example of a flagged model can still be the right buy, and any of these still needs an inspection.
