Was driving down the road when it started making a metallic noises then all of a sudden the car sputtered, shot flames and smoke out from underneath the car and metal debris went flying. I had to tow my car to the dealership where they still have it. They said there is a hole in the engine block where a rod was thrown. After this incident we looked more into the problem to find that other Hyundaia have had the same issue. No check engine light came on, the car didn't over heat or anything it was random.
