The contact's daughter owns a 2014 Kia Optima. The contact stated that while driving at 45 MPH, the engine stalled and shut off. The vehicle coasted to the shoulder of the road. The contact stated that while attempting to start the vehicle, the engine failed to restart. The vehicle was towed to the dealer, where it was diagnosed with an engine failure and it was determined that the engine required replacement.

I was driving normally on I-76 when suddenly, I couldn't feel the gas working. Everything was fine with the car until then, but all of a sudden, I saw all the lights on the dashboard. I could slowly smell the smell of flames, and later, it caught fire! I was terrified for my life, and seeing that happen to my first car, which I had only had for three weeks, still haunts me.

The contact owns a 2014 Kia Optima. The contact stated that while driving at an undisclosed speed, the vehicle was consuming an excessive amount of oil. The contact stated that a quart of oil was added every 600 miles. The contact stated that the dealer had replaced the engine with a rebuilt engine under an unknown recall seven years prior. The dealer was informed of the recent failure and informed the contact that the manufacturer approved an engine replacement if the engine failed. The manufacturer was contacted by phone, and a case was filed. The failure mileage was approximately 40,000.

The component was the engine. The engine has since been replaced. The safety of myself or others was not in immediate danger before the engine seized. Luckily my mechanics employee was test driving for other issues at the time. My mechanic said it was likely due to the recalls that have been issued from KIA. Unfortunately the engine was seized so the dealership I had the car towed to was unable to inspect the motor for the recall because of the engine seizing. The vehicle was not inspected by any of the listed entities. There were no warning lamps messages or any other symptoms of the problem prior to the failure/seizure of the engine.

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.

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...

The dealer stated my engine repair is not covered under the recall/warranty because an ECU software update was not performed. I was quoted $8500 for engine replacement (Long block). I have owned this vehicle for 2 months, going on 3. I am requesting a review of whether this vehicle qualifies for any engine recall or safety-related warranty coverage, as the explanation provided by the dealership appears inconsistent.

The car is available upon inspection, the car caught on fire after being driven for about 45 mins. Smoke started to come from under the car hood, fire starting dropping from underneath the vehicle and then fire started coming from under the hood of the car. The car started smoking while being inside vehicle and the fire could've spread. The fire was put out by the fire department, the vehicle has not been inspected as of yet. No warning signs.

My vehicle was having engine problems in 2024. It was towed to the dealership because it was a recall on it. The new engine is malfunctioning as well causing me to lose power while driving. I have only put 2,000 miles on the car since the engine was replaced.

My vehicle was leaking oil an oil change. My vehicle started having a knocking sound. I am a single parent of a [[redacted]] child.

Issue: My 2014 Kia Optima has repeatedly experienced overheating, flashing check-engine light, and loss of coolant. The dealership has misdiagnosed the issue multiple times and returned the vehicle to me in unsafe condition. Safety Concern: The vehicle overheats while driving, the check-engine light flashes, and the engine loses power. This creates a serious risk of engine failure while on the road. I am concerned about potential engine damage, stalling, or fire risk due to overheating.

While driving down the highway, my engine completely turned off. I was able to get to a safe location. When I tried turning the car back on, it would not turn back on. I took it to Kia, and they said I was covered under warranty due to their settlement. However, due to the salvage title of the car, they will not replace the engine, even though that is what their recall settlement covers.

Motor blew going down the road.

Check engine light was flashing and the car wouldn't accelerate up to speed, wouldn't turn over when tried to start.

The engine failed after a prior engine replacement performed by the manufacturer. The failure caused the vehicle to become non-operational and created a risk of sudden loss of power and engine stalling while driving. The vehicle required towing and could not be safely driven. This is a repeat engine failure involving the same vehicle.

My oil pressure sensor failed and is leaking oil into the electrical wire harness and all over the engine including intake and exhaust pipes which is a fire risk. It is the exact same issue as another recall affecting 2011 to 2014 kia models/years: 2019 safety recall (RCONL-19V101-0000) that involves replacing the oil pressure switch in certain 2011-2014 models if a leak is found. Additionally, a 2022 Technical Service Bulletin (MC-10210268-0001) extended the warranty for the oil pressure switch replacement to 15...

My 2014 Kia Optima is burning oil heavily and emitting fumes into the cabin. The dealership confirmed an engine issue but said they are waiting on paperwork to replace the engine. I've been told to continue driving it even though the burning smell enters the car and causes headaches. I believe this is a safety hazard.
