NHTSA Complaint #11437892 — 2016 KIA SORENTO

Basically my car stalled on me while driving on the feeder of the freeway. I had all three of my children inside the car so luckily nothing bad happened when my car died. I had to tow my car to a mechanic who later informed me that my engine had pieces of metal inside it. He then explained that the dealership should replace our engine since there has been recalls for this same issue on Kia Sorento. At this point, I called the dealership and they refused to replace our engine and stated that I should of done a previous recall (an upgrade). I advised them that I never received any information in regards to a previous recall and I actually had went online a few months ago and checked for any recalls. My Mom had ran across a website and we all checked all of our vehicles for recalls. My Kia Sorento had no recalls. What is my next step to get the Kia Dealership to fix my vehicle? Ive already called the main number to Kia and they were no help either. Thank you for your help!!!
