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.

Check Engine Light Due to False Intake Air Temperature Sensor Code

The Check Engine Light may erroneously illuminate, signifying a fault in the intake air temperature circuit. If no fault is found in the sensor or wiring, a simple reprogramming of the powertrain control module (PCM) may fix the problem.
