This complaint is filed regarding an under-hood thermal fire incident and unauthorized modification involving a federally mandated safety recall for a 2018 Genesis G80 (VIN: [XXX]). To resolve a starting issue, technicians at Van Hyundai in [XXX], bypassed the standard ignition circuit and installed an un-fused manual starter bypass switch kit. This bypass directly conflicted with active NHTSA Safety Recall Campaign 24V107000, which requires a specific fused relay kit (Part 91950-DH15KQQH) to prevent engine fires. This unauthorized, un-fused modification caused a severe electrical short and a subsequent thermal fire incident under the hood. The fire physically melted and destroyed the recall component and adjacent wiring infrastructure. The dealership and corporate office are now refusing to fix the fire damage they caused unless I pay out of pocket. I request an immediate federal investigation into this hazardous repair practice that completely compromised a critical safety recall remedy.
