The engine on my car stalled while driving on the highway. I was able to pull over and get it started again. I turned around to go back home and it started knocking and stalled again. After that, it would not start again. I had it towed to a repair shop who said the engine was seized. They were able to get it started again but it was knocking loudly. I ended up having to replace the engine which cost close to $6000 for a used engine. I had close to 127,000 miles on the car (I drive 100 miles per day for work) and Hyundai would not help since I am out of the warranty mileage.
