NHTSA Complaint #11493903 — 2013 HYUNDAI ELANTRA

First engine replaced at ~ 60,000 miles under warranty by Hyundai due to bad bearings. My current engine, now at ~ 118,000 miles is exhibiting the same symptoms as the first engine, i.e., knocking and a burnt oil smell. Hyundai tested the engine and once again, determined via testing the bearings are bad again but now claiming they are not responsible for replacing the second engine under warranty. I've seen many reports and have spoken with personal contacts about Hyundai/Kia engines suffering catastrophic damage sometimes resulting in fires. I have three kids who regularly ride in this vehicle and so as a parent, I am concerned for their safety but also that Hyundai seems to be evading their responsibilities as it relates to the product warranty and the safety requirements of the NHTSA. No warning lamps or other vehicle indicators directed me towards this problem. Instead, I can hear the issue which prompted me to perform an independent oil analysis followed by a visit to the Hyundai dealership for an inspection. Now, it appears that I will be stuck with a defective, fire prone engine, that I may incorrectly become my financially responsibility to amend. If so, why should I expect this third engine, or the fourth, or the tenth to be any different or more safe. Thank you from a very concerned father and husband with extremely high mechanical aptitude.
