Unknown. The vehicle has this recall and Kia still doesn-??t have a solution. It-??s been more than 6 months and I want to ensure my car is safe to drive. I am unsure if there are any issues with my car, I am simply just wanting a remedy for this part if the car is being recalled.

There's something going on at the Kia dealership in Wake Forest (Westgate). Per the current recall notice, the lights came on that were highlighted in the notice ( -??MIL-??, ABS warning light) so I had my car towed into the dealership. They claimed my car had a bad battery and the problems were not due to the recall situation. I took my car out of there and straight to auto zone, about 200 feet from the dealership. My battery tested fine. Not only this, the lights (check engine, and others) were no longer illuminated and the radio was mysteriously working again. I'm not sure what they did to my car, but they charged me over $200 for a diagnosis. Not only this, they cited several other issues with the vehicle that I nor my master mechanic were aware of. They had my car for several days without so much as a phone call. In addition, while I was waiting for the keys to my car (which took 15 minutes to obtain), I overheard the other gentleman inform a kia owner via phone that her car was not covered under the warranty because she had over 150K miles on the car. I'm so disgusted. This is what happens every time we have to take a car into a dealership. They're full of baloney.

A recall has been issued for my 2011 Kia Optima. I received a letter from the NHTSA with my VIN on it. I am concerned about the safety of me and my family. I am being told that there is no remedy for the HECU. The recall says it can experience a fire in the engine compartment while parked or while being driven. I find that possibility quite scary. What am I to do" What is considered a reasonable amount of time for this to be fixed" The recall was issued nearly three months ago. Each day gets more and more frightening.

My car towed to Kia of Lincoln in Lincoln, Nebraska where the car parked there right now. Please contact Kia at Lincoln and I better hope warranty are accepted and diagnostic are free too. Thank you!

It appears I have a defective oil pump in the car which I think is what caused the engine to go bad to begin with. I am requesting that KIA of Denham Springs be authorized by the main office of KIA to install a new oil pump in my car after the new motor is installed, otherwise the new motor will probably go bad and will result in Kia having to install another motor for the car. I hope you can step in and assist me in getting a new oil pump installed as this would be a safety issue of the car breaking down on the road and could result in myself or other passengers possibly stranded on the highway. A engine compartment fire could happen if the engine gets too hot due to the deflective oil pump no keeping all engine parts oiled properly by the defective Oil Pump. I am requesting that the National Highway Traffic Safety Administration's office look into this matter. Thanks for your assistance Tommie McMorris 985-969-8995 email: tommieap@charter.net

2011 Kia Optima caught on fire while driving. Car started smoking which was the only indication something was wrong then all the dashboard lights came on and brakes no longer worked. About half a block later I put the car in park and it slowed down enough for my 3 kids to jump out although the car was still moving. I was able to exit a few seconds later when it came to a full stop. Within minutes it had flames coming from under the hood that continued until the fire department was able to put it out. They said something electrical had caused the fire.

Safety: It appears the vehicle in question has had Engine, Electrical, and Driveability issues within less than 8,000 miles of it being on the road the First record of this vehicle show's one owner, purchased not from a Kia Dealership but a third party. The Carfax history showed there has been a driveability issue an ECM Module has been replaced twice" less than 30,000 miles" It's Believed that the warranty or millage has been used as a reason to deny repair and or Because as the Recall on the engine states it is undetermined as to what is causing a malfunction but it has or will result in fire. This becomes a liability for those who offer works on the vehicle. Something within the vehicle is without warning causing the vehicle to randomly fail while descending from 65-85 miles an hour. There are also sudden jerks that randomly accrue. rendering the car hard to maintain direction. Imagin a first-time driver attempting to handle this on a busy Highway in Texas - The day we acquired the car we took it to KIA to do a full inspection - oil change, etc- The report given was that there are no problems identified but a computer module may need to be changed. We also asked that they give us an appraisal it was at that point they said that the car had a salvage title. Which the seller who sold it us ARELLANO AUTO SALES sail the title was clean. Last year a recall on the engine was issued. the insurance company determined the vehicle a total loss since how the car was branded a lost because it appears Kia refused to Fix the car, While everyone else says they can't recreate the issue for fear of liability. So here are with a car that has an undetermined engine issue that causes other electronics to malfunction. The vehicle has been seen at KIA dealerships according to the carfax. It's been seen. By two other service facilities and all have come up with something that may needed to be service while nothing has fixed the car

My Kia has a long acceleration lag. It is so dangerous to operate this vehicle. When I press gas pedal vehicle doesn't accelerate randomly, sometimes accelerate but sometimes not. I don't have any warning lights show up. No codes. This problem occurs when the vehicle is warm never when cold. When warmer outside temperature the more often I feel this issue. Last my visit to the Kia dealer doesn't resolve this problem. They said no codes no diagnosis. In my point, this is a software or control module issue. Reading a lot of forums I found that other owners have the same acceleration lag problem. Also, I'm feeling that this issue is a serious concern that can cause a fatal accident.

The Kia Optima 2011 motor no longer works and smoke keeps coming out when it's on and turned off after driving from the exhaust on the drivers side. The accelerator pedal gets stuck and doesn't seem to want to make the change in transmission. I took the car to two different mechanics and both of them come out with the same diagnose. Was told that the car is a recalled car because it is to soon for the motor to be shutting down since it only has 81,000 miles and it's not an old car. The suspension is also not in properly.

So one of the Kia dealers in the state of Maine replaced the motor in our 2011 Optima, ever since then our air conditioning system has not been working. I've had it tested and recharged. Still no acc. I have diagnosed no power to the ac pump. Also the headlights have new bulbs in low beam and are dim..??

I was on a curvy back road doing about 45mph applying the breaks not to stop but only to break my speed down some in order to go around the curve. While doing so my steering wheel locks up, it feel as if my tires are sliding & it feels like my breaks could be locked up as well. The next day I was getting off of the interstate on a ramp and again applied my brakes to break my speed down and the exact same thing happen. My wheel locked up, felt as if my brakes were locked up as well & my tires may have slid. I'm not noticing of my car is shutting off because when it is happening I'm too focused on the road & not losing control. But I am noticing that my radio is booting up. Which it only does this when I start up my engine.

I have a theta II turbocharged engine 6 speed manual and I was driving down the street taking my son to work. All of a sudden my car started making a loud knocking noise and wouldn't go past 2nd gear. We called a tow truck had it sent to mechanic they did a diagnostic test and 2 P codes came back from crankshaft and controls and seized engine. So I had it towed into weston Kia dealership. Plus I had just bought this car in April. The dealership ship called me saying they were going to replace my engine and wiring and computer and sensor chip. Also my passenger air bag light has been blinking off 3 days after I bought it and still is. My emergency brake doesn't work and rolled while it was pulled up in neutral and hit my daughter as she was running around the front of the car to the passenger side right in her knee cap. I got my car back from weston and it didn't feel right. Someone put 380miles on my car it had a 1/2tank of gas and my clutch and clutch pedal and gear shift was way shorter and 1/4 inch off in shifter box. I was on the freeway driving 60 mph with my kids and we were leaving my parents house from xmas. All of a sudden I almost list control of the car my clutch pedal fell to the floor. I got us to safety almost avoiding a huge wreck and had it towed to my house. Called dealership and told them and had noticed on invoice their technicians had tightened up by bolts and flywheel. Well I go outside and theirs fluid all over the pavement under the car but none on inside. They paid for a tow truck and by the way since replacing the new engine I went from 34 miles to the gallon to 20 and passenger air bag still illuminated off. My defrost isnt working now and my engine light blinked 3xs. They want me to pay 1500 for new clutch.their tech adjusted my flywheel bolts and clutch cable. $65 emergency brake and $125 for test. It already had one. Fuel leak?
