12v connector for phone charger melted my phone cord. Reported to Centennial Hyundai Las Vegas and High Desert Hyundai Kingman Az. Both service departments said my vehicle cannot detect the problem because I purchased a substandard plug-in. I have worked as an operator of high voltage electrical systems. I understand in some circumstances that a system cannot detect a fault, however the company is still responsible for the fire it caused. This is unsafe and can cause serious consequences. It must be corrected.
