NHTSA Complaint #11612925 — 2014 HYUNDAI ACCENT

I was entering highway on entrance ramp there was a loud pop and I could see plumes of smoke coming from under the car, so I turned the ignition off on the car and pulled over to the shoulder, the brakes failed so I had to let it coast to a stop. Then I waited until I could safely exit the vehicle and did so quickly. I had the vehicle towed to a local shop, and they told me I should report it. There was no warning that it was about to happen and yes its available for inspection still sitting at the shop I had it towed to. They also said I should have it towed to the manufacturer service center but this is my first time dealing with anything like this so Im unsure what to do. I did do a cursory inspection under the hood with a mechanic from the shop and there was a burnt wire and a bunch of what looked like oil down at the bottom of the engine, but the oil was still full so I dont think it was oil.
