2020 Kia Forte: engine and transmission complaints

HIGH COMPLAINT SIGNAL
50%
34 of 68 relevant owner complaints are about the engine, transmission or fuel system

50% of relevant owner complaints filed with NHTSA on the 2020 Kia Forte are about the engine, transmission or fuel system. That is a model-level pattern, not bad luck.

Worse than 64% of the 1,230 model years we track (2010–2023).

Excludes 7 airbag, lighting and seat-belt recall complaints that would otherwise mask the signal (unadjusted: 45%).

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.
