2012 Kia Optima Problems

Front Door Will Not Open Due to Faulty Latch

A faulty door latch assembly may cause one or both front doors to be difficult to open. Replacing the worn latch will commonly correct this problem.

Software Update Available Which May Correct Transmission Issues

Reprogramming the transmission control module with the latest Kia transmission software may fix abnormalities in the automatic transmission and erroneous transmission-related Check Engine Light illumination. Software updates are commonly most effective on newer vehicles. Higher mileage vehicles may exhibit a similar symptom caused by a component failure. However, whenever major transmission repairs are performed the transmission software should be checked and updated as necessary.

Faulty Throttle Position Switch

Check Engine Light illumination—combined with a lack of power or a stumble on acceleration—may be caused by the throttle position switch (TPS). Kia released an improved part which should correct this concern.
