I had just stopped at stop sign and I turned right. My speed was approximately 40 mph and there was a LOUD POP. I immediately hit the brakes and had NO BRAKES. I got car off road and smoke was already coming from under hood. It caught fire immediately and burned up. Total loss . About 6 months prior to it burning I had a good bit of front end work done on it with bearing issues. Also put a new set of tires at same time . The coils and plugs were changed often because it would misfire. I purchased car July 2025. All my documents were burnt also .

ENGINE
Engine faílúre on June 26, 2026.Dies while moving. Engine died while turning from my side street onto busy street and traffic.I could've been struck in the rear had I not pulled out far enough in advance for the traffic to move around me. This is a second engine failure for my Kia. The engine was replaced in December 2023/ January 2024. Incident #11558201. It does not immediately restart. After some time (about an hour) it takes a long time for it to kick over then finally starts. When beginning to move forward it travels approximately 100-150 feet then dies again. A gentleman stopped to see if he could help. He thought the fuel gauge was broken and just needed gas. (Gas tank was full). Then he put the car in neutral and pushed me home with his truck. Then he helped me push it up into my driveway. I haven't gotten to the dealership (Ferguson Imports) Kia because of the cost of towing which I am responsible for if I wish to have it seen by a service specialist. It is available for inspection upon requést.

The paint on my car is delaminating. There are bubbles throughout the car and a few huge bubbles have popped and now the bare body is visible. I have called Kia corporate and they have denied my request to repaint the car. They are telling me that the is a three-year warranty on the paint. My car is only seven years old, and the paint should not peeling/bubbling. I have taken my car to a collision center, and they believe it is caused by a defective manufacturer paint. After looking online, it is a nationwide chronic problem with snow white pearl. Kia is totally aware of this and doesn't want to address the problem. I do know there are many lawsuits against Kia for this particular problem. I am seeking help to get this resolved. Pictures attached.

STEERING
Since 4/1 my car has intermittently lost power steering. I received dashboard warning lights and the wheel was difficult to turn. When I shutoff the car and turned back on, the warning lights were gone and the steering returned. My mechanic did a diagnostic and found the following codes c1259, c1260, c1290 and c1688 each time the incident occurred. After research, we discovered these codes relate to TBS CHA114 and TSB CHA864 under extended warranty WTY023. I was unable to upload the TBS documents. The same thing happened on 6/18. I brought the car to a different dealer. The first time they supposedly did a diagnostic and said there were no codes. I have pictures of the codes. They said it did not matter because the codes need to be active and the lights need to be on the dashboard. The second time at a different dealer, they didn't do a diagnostic but said it did not matter because the codes need to be active. No where is any documentation does it say the codes need to be active. They are stored in history and Freeze frame data. It is impossible for me to get the car there with the illuminated dash and "active" codes because when it happens, I cannot steer the car and when I shut if off they go away. Plus when I get to the dealer, they will tell me they cannot take me and to make an appointment. I am now working with KIA escalation department but she informed me today that she did not have the authority to authorize a dealer to repair the car. When I asked who does she said I need a techline which is opened by the dealership. WHAT??? This all started with the dealer. The car is now having glitches with the steering while driving. IT IS DANGEROUS AND I AM AFRAID TO DRIVE IT. I have no idea when the steering might go out. I need help in getting a Kia dealership to fix the issue under the extended warranty they sent me in 2022. I am so sick of the run around and brush off. How do I get this accomplished?

ENGINE
The car burns oil within a week of getting an oil change. It was only driven a 200 miles before all of the oil was burned out. This has been a consistent issue with this car that the oil burns at an extreme rate. This is a safety risk as it could lead to engine overheating, the engine could stall out due to the fast burning of the oil, or a potential fire hazard while driving. The oil light will come on for a second and at that point, the oil is already EXTREMELY too low. I brought the car to the mechanic and they have told me multiple times that there is no leak or anything. The mechanic says that the car simply is burning oil too fast.

ENGINE
The component that failed on my 2014 Kia Optima was the engine. Prior to the malfunction there were no lights indicating a failure. My safety was put at risk several times as my car had completely shut down on the highway going over 55 mph in way of many vehicles causing police to shut down the highway. I took the car to several auto shops to test and there was no indication of engine failure. I’ve got my battery checked, front end alignment and oil changed on schedule. The car still malfunctioned. I had it towed to the Kia dealership in March after learning about the recall on the engine. The dealership confirmed that the engine was faulty and had been recalled. There were several other recalls on that model as well. After keeping my car for a few days and charging me a service fee, they decided not to repair the engine saying that the software was not updated prior to the engine failure and they refused to repair. I was instructed to remove my car from the facility. I called their corporate office and a representative also denied my claim saying that the mileage on my car was too great. I have not been able to get in touch with anyone that can help. The car is located in a shared parking lot amongst hundreds of tenants and close to residential areas. I don’t believe it is a safe area if there is a fire risk but Kia refuses to honor their recall. The car is available for inspection upon request if needed.

ENGINE
While driving my 2015 Kia Optima, the engine failed completely without warning. The vehicle lost power while in motion approximately 300 miles away from my home. All warning lights illuminated and the car shut down during driving conditions, creating a serious safety hazard. The vehicle was towed to a Kia dealership where it was inspected. I was informed the engine has failed and may be related to the known 2.4L engine defect and prior recall campaign involving this engine type. This vehicle has a history of multiple recalls, including engine-related recalls issued in 2018 for the same engine family. The failure occurred suddenly and without prior adequate warning, and the vehicle is now inoperable. I purchased the vehicle in May 2023, and at the time of failure it had approximately 133,000 miles. The engine began knocking loudly prior to failure, then stalled and shut off completely while driving. This incident placed me and others at risk because the vehicle lost propulsion while in traffic. I believe this may be related to a known manufacturing defect in Kia 2.4L engines that has been the subject of recall and/or investigation. I am requesting that this complaint be documented as a safety-related engine failure potentially associated with the existing recall and that it be reviewed for further investigation and manufacturer accountability

ELECTRICAL SYSTEM, ENGINE
1. What component or system failed or malfunctioned, and is it available for inspection upon request? The primary failure involved the engine. The vehicle experienced a major engine failure that resulted in an engine replacement under a manufacturer recall. After the replacement engine was installed, the vehicle later developed additional engine-related problems. An independent mechanic advised that the vehicle would require another engine replacement or extensive engine repairs. Additional defects included a malfunctioning moonroof that would no longer close properly and other mechanical issues affecting the vehicle's operation. The vehicle may be available for inspection depending on its current status and location. 2. How was your safety or the safety of others put at risk? The repeated engine problems created concerns about the reliability and safe operation of the vehicle. Sudden engine failure while driving resulted in loss of power, inability to maintain speed in traffic, and being stranded in unsafe conditions. The ongoing mechanical failures caused significant concern regarding the vehicle's dependability and safety. 3. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes. The original engine issue was confirmed by authorized service personnel and resulted in an engine replacement under a manufacturer recall. The subsequent engine-related problem was evaluated by an independent mechanic, who advised that the vehicle required another engine replacement or significant repairs. 4. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives, or others? The vehicle was inspected in connection with the original engine recall and replacement. It was also inspected by an independent mechanic regarding the subsequent engine issues. At this time, I am not aware of any inspection by police or insurance representatives related to these mechanical failures. 5. yes, right away

ENGINE, FUEL/PROPULSION SYSTEM, UNKNOWN OR OTHER
My 2016 Kia Optima equipped with the 2.4L DOHC I4 GDI engine began to experience progressive and severe oil consumption during the latter part of my ownership. The oil warning light began activating repeatedly, even after shortly getting the oil changed. Several certified mechanics and oil change service stations told me this was an ongoing issue with this car and engine and that there was nothing I could do but monitor it and keep it filled. At their instruction, I monitored and had it changed more frequently, often topping it off at the oil change station and at home when needed. Approximately 2 weeks after an oil change upon putting the car in reverse it started to shake uncontrollably. The car was towed to a mechanic who stated I needed an engine. I then towed it to an authorized Kia franchise dealership where the technician documented the oil consumption complaint, confirmed a Cylinder 2 misfire code, performed a borescope inspection, and found the Cylinder 2 exhaust valve burnt with a chunk missing. Engine replacement was recommended by the Kia dealership technician. Prior to my purchase, the engine had already been replaced at approximately 80,000 miles under recall-related circumstances. The replacement engine installed by a Kia dealership subsequently failed, exhibiting symptoms consistent with the documented widespread defect affecting the 2.4L DOHC I4 GDI engine in 2016 Kia Optima vehicles, including severe oil consumption, cylinder misfire, and catastrophic internal engine damage confirmed via borescope at a Kia franchise dealership. Kia America denied the claim based solely on mileage despite the damage being confirmed by their franchise technician. My vehicle became unsafe to drive due to this engine instability shortly after starting before becoming fully inoperable. My vehicle has been non-operational for approximately 5 months. Kia has not provided a substantive written determination despite a formal written demand submitted in March 2026.
