    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 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…

    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 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.
