I was accelerating on the highway and my RMPS shot the whole way up over 7,000 then bottomed out. I lost speed so I pulled over. Another car pulled over to inform me my car was on fire. I turned the car off and the fire went out. The car was towed to Blaise Alexander (dealership) in Altoona, PA. The mechanic reported that a connector rod went through the oil pan, engine block, and brake starter. He kept repeating to me "I've never seen anything like this before". He reached out to Hyundai to ask if they would cover repairs (starting at $13,790). Hyundai said no. I believe this incident was more than mechanical, and is related to the open recall. I attempted twice to have my car repaired under the recall but the dealership "didn't have the part".
