On January 15, 2019 my 2015 Kia Optima caught on fire while my 16 year old daughter was driving down the highway. She smelled a strong fuel smell first then tired to stop the car.

The contact owns a 2015 Kia Optima. While driving 70 mph, the contact detected a loud, abnormal noise coming from the vehicle. As a result, the contact noticed smoke under the hood. A police report was filed. When the hood was lifted up, the fire extinguished itself and only smoke remained. The fire department was present and stated that the exhaust had burst and oil leaked out, which caused the fire. There were no injuries sustained. The vehicle was towed to a local tow yard. The vehicle was not taken to a dealer or independent mechanic for diagnostic testing or repairs. The manufacturer was not made aware of the failure. The VIN was not provided. The failure mileage was 80,000.

Optima

  • 68,000 miles
2015 Kia Optima with approx 68,000 miles. Going up hill up a ramp to merge onto highway around 40 mph when the check engine light illuminated and would no longer accelerate. Shortly after, the oil and battery lights illuminated and car coasted as far as possible into shoulder as I could. Car would not restart. Sat on the on-ramp for quite a while partially blocking traffic and almost had some near miss accidents from other drivers passing and honking at me. Towed to Kia dealership same morning. Tech believes my engine has seized but no official diagnosis. They provided me with a loaner car at no charge. I am original owner and hope Kia will replace my engine at no cost and buy my car back. I am scared of the vehicle fires that are happening with these engines for other people. My car gave me no failure warning until it was too late.

I was traveling at 65 mph on a straight and level highway in my Kia Optima (which has less than 60,000 miles), the check engine light came on and I lost all power. I could have lost my life. Car was towed to local repair shop who determined that vehicle needed to be brought to a dealer. Barry henderson, the repair shop manager, said there is a possible wiring issue and if the wiring is okay, the engine needs to be replaced. He told me they couldn't repair so the car was towed to hyman brothers Kia in midlothian, va. All required maintenance has been done on this car and hard copies of all of the service records have been place on the front passenger seat as proof.

Optima

  • 65,000 miles
Around 55,000 miles I started having low oil and having to add oil, shortly I heard some rattling under the hood. At this time I also started to notice white smoke from the tailpipe when I would accelerate. I took it in to the dealership and they refused to cover it under warranty saying I did not maintain the proper oil changes. I offered proof of all my oil change receipts and they still denied to fix it. I could not afford the fix they say needed to be done so I just decided I would just add the extra oil to the engine every week however around 63,000 the engine blew. Now currently the car is at the dealership and I am awaiting to see what they will do about it. I have read so many complaints on this exact issue on this car and I expect them to fix my car.

Optima

  • 130,000 miles
Had oil changed and a month later noticed the car making a knocking noise and skipping while driving on city street and highway. Had the oil rechecked and the car was out of oil. First thought that the oil place forgot to put oil in. However, it was later determined by a mechanic that the valve was gone in the engine and I would need a new engine at 130,000 miles in a 2015 Kia Optima LX. The car stopped on the highway at 70 but I was able to move to the side.
