2019 Kia Optima: engine and transmission complaints
HIGH COMPLAINT SIGNAL
54%
102 of 190 relevant owner complaints are about the engine, transmission or fuel system
54% of relevant owner complaints filed with NHTSA on the 2019 Kia Optima are about the engine, transmission or fuel system. That is a model-level pattern, not bad luck.
Worse than 70% of the 1,230 model years we track (2010–2023).
Excludes 16 airbag, lighting and seat-belt recall complaints that would otherwise mask the signal (unadjusted: 50%).
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.

This does not say whether a particular car has an open, unrepaired recall. That depends on the VIN.
Before you buy a 2019 Kia Optima
Ask the seller whether the engine has ever been repaired or replaced, and whether the car has shown stalling, loss of power, rough idle, oil consumption or a check-engine light.
Drive it from a cold start and long enough to warm up. Many engine faults hide once the car is warm.
Get an independent pre-purchase inspection from a mechanic you choose, and tell them to focus on the engine.
1 recall campaign on this model year. Whether a specific car still has one open depends on the VIN; the report checks that.
Ask for service records. A engine already replaced under warranty is a different car from one that was not.
Have the VIN?Paste it and get the full report for that car. First report free, then a 30-day pass covers a whole car search.
