2012 Kia Optima Problems

Kia Issues New Alternator to Replace Weak One

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.

Door Locks Malfunction Not Allowing Driver or Passanger to Open Their Doors

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.

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.
