2015 Kia Optima drivetrain & axles problems

Driving north bound on the 405 at freeway speeds, the vehicle showed several warning lights on the dash. Check engine light, oil light and 2 others, the vehicle lost engine power and only had brakes. I was able to shuffle off the main freeway to an off ramp where I pulled over to attempt to power the car back on. The smell of electrical fire started to become apparent and I went out to lift the hood and smoke began to come out the opening.
