NHTSA Complaint #11537925 — 2015 HYUNDAI SONATA

What component or system failed or malfunctioned, and is it available for inspection upon request? My engine stopped working while I was driving on the highway from Texas to Norman. This happened when I tried downshifting from 6 to 5. How was your safety or the safety of others put at risk? I had to find a way to maneuver from the fast lane to the side of the road without putting myself or any other road user at risk. Has the problem been reproduced or confirmed by a dealer or independent service center? After several failed diagnoses from different specialists such as auto locksmiths and other mechanics looking at the alternator and starter as possible causes of the problem, I had to have it towed to the Hyundai dealership in Norman to have it diagnosed and I was told that it was very likely to be an engine recall issue with a motor inside the engine having locked up. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? It was inspected by Hyundai Norman and they confirmed that it was the engine recall issue, but after sending it to Hyundai headquarters, they are unable to work on the problem due to my vehicle having a salvage title. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? There were no warning lamps, messages or symptoms prior to the engine failure
