NHTSA Complaint #11577722 — 2017 HYUNDAI SANTA FE

Catastrophic engine failure on a major highway. Just over 113k miles on it. 1 day prior, the car sounded louder than usual but otherwise, was working fine. I drove several places the next day and the check engine light came on towards the afternoon (yellow, not flashing, no other lights) 30 minutes before this issue occurred. I was accelerating on a busy highway and all of the sudden it completely downshifted, oil light and battery light came on. I pulled to the shoulder and white smoke was coming from the engine, horrible smell in the cabin. Car was dripping oil. I was told it was a broken rod that punctured the engine. I could have been in a major accident after decelerating so quickly on this particular highway and I was stranded on a very small shoulder fearing the car or myself getting hit for hours. As of right now, the engine is still available to be inspected.
