NHTSA Complaint #11486241 — 2018 KIA SOUL

We bought this car from Carmax this year back in January for my daughters birthday. It had 63000 miles on it. Thought it was covered up to 100,000. We were driving down the interstate when the engine started knocking and loss of power. Pulled over and checked the oil, it was good but you could see a lot of shiney small metal shavings in the oil. Plenty of oil though and oil was changed a couple weeks before. There were no lights on the dash panel to warn you even as it sits there and knocks. Just got told by several mechanics the engine needs replaced but the warranty is out because I’m the second owner and it has over 60,000 miles on it so therefore it’s not covered under warranty. This seems to be a constant issue as I’m reading the same problem happening. Hoping Kia will work with me since I have 2- 2018 Kia Souls.
