Geo...while all that you stated may be valid, with 8k out of warranty you'll be hard pressed to get Kia to cave in on this one.Be sure to go to safercar.gov & file a complaint with NTHSA (it only takes a few minutes).
Read up there on any other complaints like yours & review any Kia communications on the issue.
That's fairly high mileage (usage) for a 2015. Review your service records to make sure you were in compliance on required/recommended service.
IMHO I believe when you hear the words "sorry but you're just out of warranty," it's bs. I feel that a normal person would expect more than 108,000 miles on an engines (based on, well, just about any other brand on the market).
An engine that "dies" at 108,000 inherently was flawed the day you bought the car, well within the warranty, provided you maintained it. It just didn't reveal it's flaw until now.
All the best.
Too many factors affecting durability I am afraid.It is a durable good, it should last longer than that. If a lawyer wants nothing to do with it, talk to your local TV stations and see if they are interested in the story. Some negative press about Kia may get things going. A person should not expect their motor to completely fail within 8,000 miles after the warranty period. If for the only reason that the owner will never buy that brand again, and neither will anyone he/she talks to. If the talking spreads beyond a small forum where the manufacturer doesn't care, then it might pick up momentum.
Not sure if this will link, but google Kia engine failure and you should find the same thing https://www.usatoday.com/story/mone...-fires-hyundai-kia-engine-failures/739097002/ Is this what happened to you? Who knows, but it could be related to your failure.
