Engine light comes on and engine shuts off while driving. This occurred twice on the freeway and once on a city street while the vehicle was in motion. Vehicle only has 1800 miles. I have taken it to the Hyundai dealership for repair numerous times. When I pick it up they say "its been repaired" but hours or days later the same problem occurs. I demanded that they void the purchase contract but Hyundai refused. I had to retain an attorney who recently filed a lawsuit against Hyundai regarding this matter (case # 15k14065).
