NHTSA Complaint #11473473 — 2016 HYUNDAI SANTA FE

My 2016 Hyundai Santa Fe's engine just stopped on me on Friday afternoon June 17th. Driving home from work on a busy road my car began to make load noises & the engine light began to blink, within minutes my car died going about 45 mph, luckily I was able coast into the entrance of a neighborhood. The car would not start back up and I was stranded more than 20 miles from home. Only hours earlier I was on several major expressways and it frightens me to think of what could have happened if my engine stopped working earlier than it did. I had to have the car towed to the dealership from which I bought it. I was hoping they could fix whatever the problem was however they told me that my engine seized and it needed to be replaced. The car has since been at the Dealership, Rosen Hyundai of Algonquin, ever since. I bought the car used in February 2021 with 87K miles on it. The dealerships service department submitted a request to Hyundai USA to replace the engine but Hyundai USA has denied the request twice now. Unfortunately We owe $11k still as we have not even had it a year & a half. I discovered , upon some reserching that many people across the country have had or are currently experiencing the same issue with Hyundai USA. Looking for any help to solve my issue. I've been without a car since 6/17/22.The Dealership has no loaners & renting a car out of pocket is $400 - $500 per week. Please help
