NHTSA Complaint #11520238 — 2017 HYUNDAI SANTA FE

I was driving my children to school on April 25th. When I heard a knock or clunk sound with the car. Once that happened it also caused a decrease in power to the car, causing those behind me to almost have an accident. After the loud noise there was a continual loud knocking sound. I immediately stopped at the closest auto center. They advised me that I would need a new engine. I had another mechanic look at it as well, and he confirmed needing a new engine. NO warning indicators came on, no oil pressure problem, Nothing! I have always maintained the oil and fluids on the car at regular intervals. I have been told by my mechanic that he had looked at the engine on several occasions for an oil leak because my car was using more oil than he though it should, but there was never any sign of any leaks. This car had about 97,000 miles at the time this happened last week.
