“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?

“Yesterday, [XXX], My 2015 kia optima engines reved up wothout me pushing the gas & within seconds later a loud noise and metal fell from under the hood. After pulling over, popping the hood on the passenger side and under the engine a fire had started. My daughter was seated in the back passenger side her door had locked, thankfully the passenger door was left opened bc within minutes the entire car was filled with smoke and engulfed in flames. Prior to this the steering wheel would jerk even while at a red light. This car just did have 100,000 miles & no knowledge this prior. Thank god i was able to get my daughter out of this vehicle & this didnt end in a tragedy due to negligence if this was a prior known fact.”

“I’ve gotten my vehicle fixed four times now thinking it was an electrical issue, not aware of the recall. Did my research this fifth time when my brake lights completely went out and smoke at some point in times come through my air-conditioning. I’ve spent more money trying to fix the vehicle with no idea that there were issues already about it.”
