I was driving on the freeway at 65mph and experienced a sudden loss of power. I depressed the gas pedal but the car would not accelerate past 45 mph. I had to drive all the way home with my hazard lights on. There were no lights on the dashboard to signify a problem. This happened several times. I took it into the Hyundai Service center and they could not replicate the problem. It happened again. and again. and again. finally got an error
