2016 Jeep Renegade electrical system problems

My computer had started to glitch within less than 100 miles of me buying the car I was told it was because the oil was low now I have a service engine light and within a day my car has lit up like a christmas tree with every light power steering has gone and I've already gotten an accident worth almost the whole car -1 grand so it was not totaled nor can anybody explain why my car did this and I got the blame for it when I have no control over this car this needs to be recalled this happened to me on the highway…

Driving on highway at 70 MPH up a minor incline, the vehicle started hesitating/chugging and then the accelerator pedal stopped responding. Vehicle stalled and coasted to stop where the idle was rough and then died. Initially, would restart, but then stall out. For the next 3 hours (while waiting for a tow), the electrical system was flaking out - intermittently flashing any error in its wheelhouse. Restarted next day and idle very rough/misfiring, engine light blinking and decent cloud of black smoke generated.
