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 shoul...

2009 Kia Optima Problems
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.
A defective AC compressor clutch assembly can cause excessive noise or vibration when the air conditioning is on. Improved parts are available. Replacing the faulty clutch assembly does not necessitate replacement of the complete AC compressor or evacuation and recharging of the air conditioning system.

Timing belts can break prematurely and cause serious engine damage. When replacing a broken timing belt, the crankshaft position sensor should also be replaced as it most likely has suffered damage as well.
Make sure the transmission is filled with Kia-approved transmission fluid and at the correct level. Our technicians tell using incorrect transmission fluid or operating the transmission when it is low on fluid can result in internal transmission damage.

2009 Kia Optima Reviews
My wife and I both have 2009 KIA Optimas, The only issue that we have had we had it with both cars. If you have the headlights on and park and turn off the ignition swith and exit the car 99% of the time all the lights will go off. The other 1% of the time the parking lights will stay on. This is most inconvinent since sometimes you do not notice the parking lights still being on.
The dealer has no idea why this is happening. Anyone else have this issue with their KIA Optima?
We've had our '09 Kia Optima for almost a year and a half now and are very happy with it. Only 16k city miles in, but it runs/looks/feels pretty much brand new. Would love to upgrade to the nice, new '11 model...but this one is working out so well. I'll be happy with this '09 for another 2 years and 20k+ miles. Kia has got to be the most improved auto manufacturer since, well....Hyundai.
Started out loving everything about this car! Bought it off the showroom floor in March of 09 with only 11 miles on it and it drove amazing! Not even 2 years later and the car acts like it is 10 or even 20 years old. The suspension that I loved so much brand new is now incredibly rough on even the smoothest of roads and the handling is very sloppy like a huge floating Buick or something. The newest disappointment is that while slowing down for a stop sign or corner and braking the automatic transmission downshifts extremely hard from 2nd to 1st gear; feels like I am driving into a brick wall the shift is so rough, it even activates the ABS system when the road is snowy! It is insane, but the rest of the car, the not so important parts, work and look great.
