NHTSA Complaint #11493601 — 2016 KIA SORENTO

We purchased a 2016 KIA Sorrento from JTs Chrysler Jeep Dodge located at 5215 Sunset Blvd, Lexington, SC 29072 on September 27, 2021. In February of 2022, we had the oil changed and it the vehicle seemed to be burning oil but no oil leaks. We took the car to the Galeana Kia dealership on Greyston Blvd and they were backed up for months. The car has sat dormant for the past 5 to 6 months as we were searching for who could work on the vehicle. We took the vehicle back to Galeana Kia and they informed us that the #2 cylinder had no compression. They further proceeded to share with us that a recall was issued several years ago for an ECU upgrade and KSVS(not sure what that is) and this would have given them a code for KIA to authorize replacing the engine. Their claim from KIA is that since this was not done according to the lawsuit against KIA they could not replace the engine. The website that the dealership used to verify if there were recalls was https://vinrcl.safercar.gov/vin/vinLookup and i have attached a copy for review. i am now saddled with a vehicle needing an engine replacement due to improper recall reporting by the sites and lack of due diligence by the JT's dealership. What do i do now?
