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.

Battery Weak Due to Inadiquate Alternator Output

After the vehicle has been operated with electrical loads (lights, air conditioning), a weak alternator can cause starting difficulties. In some cases, the original alternator could not sufficiently charge the battery; Kia released a new alternator which can correct this concern.

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.
