Consumer Description

The contact owns a 2016 Kia Optima. The contact stated while driving 74 MPH, the vehicle made abnormal metallic banging sounds. There was no warning light illuminated. Additionally, the vehicle began to lose motive power. The contact veered to the side of the road and added engine oil to the vehicle. The contact drove to a nearby parking lot and parked the vehicle. The contact's friend, a certified mechanic, diagnosed that there were metal shavings in the oil, which led to engine failure. The dealer and the manufacturer were notified of the failure and informed the contact that they could not assist as he failed to complete the Knock Sensor Detection System (KSDS) software update. The vehicle was not repaired. The failure mileage was approximately 73,000.
