2012 Kia Optima ProblemsBattery 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.
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.
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.
2012 Kia Optima QuestionsMy a/c stopped working. And it doesn't blow any air, not even hot air. (1 answer)
I was out and parked my car, turned off the a/c. And right there and then it smelled like something burned. After that I tried to turn it back on and nothing happen. It doesn't even blow hot air, it does nothing. What do you recommend? What should I look for?
Sounds like a loose bolt vibrating against metal. I tightened two screws behind the take out side panel but still making noise. Thank you
I bought the car used and it doesn't sync properly for directions
