Kia Optima Problems

Electrical & Lights -- Verified

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.

Drive Train -- Verified

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...

Exhaust & Emissions -- Verified

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.

Heating & Air Conditioning -- Verified

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.

Engine -- Verified

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.

Drive Train, March 3, 2011

RepairPal Expert Overview:

The shift cable may have been installed incorrectly, causing tension in the cable. The tension could cause the cable to become disconnected from the shifter, disabling proper gear selection. If the vehicle is left unattended with the transmission not in "Park" and the parking brake not engaged, the vehicle could roll, increasing the risk of injury or a crash. Dealers will inspect the shift cable and reinstall it if necessary. This recall is expected to begin during March of 2011. The Kia recall number is SC088.

160k motors blown. I baby this car ty kia for your lemon

Wife has had 2005 Optima 6cylinder since new. Problems experienced same as screamed about elsewhere: head light bulbs blow out: USE ONLY FACTORY BULBS - after market last moments; Door lock system malfunctioned. Fortunately wife uses key - horror stories elswhere where locks engage when they want to and will not allow exit from vehicle - safety complaint considered minor by NHWSA (sic?)
Oh yes, lots of reports elsewhere where straps holding fuel tank rub (and trap salt no doubt) causing holes & fuel leaks.
Now big problem: Leave vehicle for a week or two and battery is drained. Dealer claimed it was the audio amp that was defective. I replaced it. Six months later same deal. "Technicians" in the dark, one voice from the tombs said "the go to sleep switch is not switching" because current continues to flow when all is turned off. Now wasting time doing their job.
Otherwise nice car

I paid off my 2004 Kia Optima Lx...I sure regret not trading this piece of junk in. My problems with this car is once in a while my key won't open my trunk...the whole passenger side of the car front & back the electrical doesn't work ..this pile of junk is a bad car period. Anyone interested in buying a Kia vehicle better think again....

I paid my car off. Now I feel like my car is falling apart. First themg key wouldn't turn and the wheel was not lock. My dad sprayed some wd40 in their key whole and it worked again. I don't know what that was about
Don't care because it works now. When I use to open the car door and take the key out the head lights usued to go out now it don't. Wish I new why, I am so use to it going out by it self that I keep leaving the lights on.
Next thing is I need a timing belt. O year and then light in my radio keeps cutting on and off by it self. I think my ac is about to kick out it keeps jumping on and off by it self to. I don't think I should of paid my car off. It only has 70thounds miles on it. I guess these problems are normal.really don't know.

th1s car has prerformed well so far. I have about 110.000 miles on it, my wife was driving
it the engine cut off and it wouldent start up again. After waiting about an hour I tried to start it again the engine turned as though it was draging and then the starter began to click.I thought that it needed a starter.The deaqler installed a starter it still wouldent start. Now they tell me that the engine is bad and it will cost $4000.00 to repair I cant believe it..
