Q: Engine lights

I own a 2012 Kia Optima LX and I had bought it pre-owned just a month ago. I was at a drive thru the other night when my car engine started to shake a bit and the engine light popped up. While exiting the drive thru, the car wouldn't go any faster than idle speed while driving no matter how far i pushed the gas pedal. I parked and restarted the car and everything was fine but the engine light was still on. The next day while coming home from work multiple lights came on and off such as the ABS, Traction Control, Tire pressure, and battery symbol while the engine light remained constant. And while puling into the driveway the steering was hard to turn and had to force it into position. I am concerned as it is a new car to me and I did have it serviced by the dealership before purchasing it a month ago. Any help to what the problem may be I would be entirely grateful.

My car has 70000 miles.
My car has an automatic transmission.
