2014 Kia Optima Fuel system Problems

On 7/13/26 around 0715 my son was driving our 2014 Kia optima when it caught fire and burned from the engine to the back of the car. Fire dept and law enforcement had to respond and the vehicle along with thousands of dollars of property was destroyed by the fire. This vehicle is a total loss and I’m trusting an investigation as to I believe their fire started due to the engjbe and electrical faults of Kia motors.

I had a fuel leak, I bought this used car from a used dealership. Took it afford kia last year where there was no fix for either the recall or the previous recall of the fuel leak (apparently it was already fixed) went to go replace part of the fuel line and it wasn't even properly fixed, they had electrical tape and zip ties around just an extra layer of rubber they put around it. Not sure who "fixed it" before but now I'm suffering the aftermath of a part of missing fuel line which I don't have the strength to get the metal link into it, and an undriveable car. I didn't even know there was a fuel line issue cause kia just told me there were no open recalls on it for anything fuel related instead of telling me there was a previous recall which clearly wasn't fixed properly.

A high pressure fuel pump, the car is at a shop to get worked on. I was told not to drive the vehicle because it can catch on fire. The part that was leaking was connected to the engine which could cause the car to catch fire if it touched the hot engine. I was scared to drive the vehicle because it smelled like straight gas, I was terrified thinking the car was going to blow up. So I parked the car , so nothing bad can happen to me or others. I also Called Kia of Waldorf and the did not have an appointment until the following week of the 20th. Yes this was confirmed by an independent service center. No there was not any warnings on the dash board. But I do know it was a recall one time before on the high pressure fuel for Kia optima’s.

Summer 2017 The engine failed while driving with my family. The engine seized and a fire was engulfed. I was in the interstate and we feared for our life. Out of town visiting family we were stranded in another state for a month waiting for repairs. Kia took the vehicle and replaced the engine with another faulty engine that has seized several times while commuting. I have been living in fear and anxiety since this incident. I never know if I start my engine if I will loose my life. Summer 2023 3 teenagers watched a viral tic tok challenge and learned how faulty the cylinder that Kia installed was. The teens then trespassed into my home, broke the windows and stole my vehicle. I have lived in fear since this has happened. I have lost jobs, income, and peace due to The purchase of this vehicle. Kia has never assisted or kept the promises they made to restore the vehicle. These past 10 years agave been a nightmare and as an African American woman I believe I was targeted as a purchaser for this make and model. My life had been hell since the purchase of this vehicle. I have not been able to satisfy payment due to repairs, thefts, fires, and more. Please anyone. Someone. Help. This is the most heartbreaking experience as an American. I have worked for my country 20 years and do not feel like an equal citizen. I have been homeless, jobless, unstable, and watched my life and family life flash before me in near death accidents involving this car. When I purchased this car I had a great job, credit score, and home. Now I have more anxiety, fear, bills, and no help with this Kia.

March 15, 2023 I Ania Covington as well as my mother Ramona Allen went to the Kia dealership in Southern Pines, NC at 10am to get a recall fixed on my car (fuel line), an oil change, air filters changed, as well as a valve gasket replacement (recall was free, everything else paid out of pocket). I received my car back at 4pm the same day, when I pulled off the lot not even a mile away my car was smoking from the exhaust pipes. I went back to ask them was it going to continue to do that, the mechanic as well as the advisor told me it’s just the old oil burning off. As I was driving home I began seeing smoke come from my engine as and still from the pipes I was still thinking it was the old oil burning off hence that’s what I was told. I decided to go to the gas station to get gas for the remaining of the week, and my car burst into flames while I was pumping gas. The fire had originated from my engine. I went back to the dealership the following day to show them pictures, the service manager(Thomas) told us to reach out to Kia corporate. It’s almost one month later, no one has been answering calls from me nor my mother. We went back to the dealership 3/31 the service manager took our information again and told us he’d reach out and still haven’t been informed on anything.

HEV Warning light comes on and says HEV malfunction, stop car. Within seconds the car shuts off and has no brakes and then stops in road construction, blocking up an entire lane of traffic, as there was no shoulder because of barricades. I panic as I can’t get out without getting ran over. After sitting for 5 minutes, car restarts and drives away ok. Car has done this off and on for 2 years. After the first incident, I took it to Kia of New Bern who charged me $400 to “update software” according to a TSB, even though it was under warranty. After getting the car back, the next day the warning came back on. I called Kia of New Bern and they said they will charge another diagnostics fee I couldn’t afford, so I didn’t go back. There are many others who have had the same issue with their KIA Hybrids. These cars are a danger to their drivers and the unknowing public who share the roads with them. KIA Should be ashamed of the amount of cars experiencing this issue and their lack of solutions to fix it.

Last Friday(01/20/2023), I was driving my car suddenly out of nowhere my car slowed down and wouldn’t start. It has just been 20days since I last serviced. Engine light was on and the other two lights where on as well. I towed it to Kia dealership and after diagnosing they said there has been a lot of fuel leak and issue with the starter so the car wouldn’t turn on. I’m not sure if this isn’t a recall, because my car was completely fine before this incident. The dealer quoted me around $560 for the fuel tube and $890 for the starter.
