NHTSA Complaint #11564749 — 2020 KIA SORENTO

My vehicle developed an unexpected oil leak, when the oil plug worked itself loose, and then fell out, resulting in a catastrophic engine failure (and subsequent $11,000 engine replacement). Upon taking it to a nearby mechanic, he discovered the plug sitting in the splash shield. The sudden loss of engine power, on the highway, created a traffic hazard for myself, and the other motorists around me; fortunately, I was able to maintain control of the vehicle, and move it to a safe location. The problem has been documented several times to the NHTSA, as well as several other organizations related to vehicle maintenance, specifically oil changes and services. There were no indications as to an oil leak, prior to the plug falling out entirely, and a cloud of black smoke billowing out from behind my vehicle.
