NHTSA Complaint #11419629 — 2017 KIA SOUL

I was headed to a family BBQ on memorial day in my 2017 Kia Soul that I have had about 2 years and is a certified pre-owned vehicle and did not notice any abnormalities or sounds prior to the incident. I went to partk and noticed that my check engine light popped on but thought nothing of it as my gas cap lock was broken and so I turned off the vehicle. I want to note there was no sounds, and no over heating. That evening I went to leave and the car would not turn over and thought maybe the battery was bad, but was reminded that it was replaced one week prior. So I had it towed in the next day to a mechanic and upon initial inspection he found that the engine had siezed and locked up as well as it would not turn over. I'm pretty good about personally completing oil changes, but was sharing vehicle with my ex partner and was told that the oil came up 2 quarts short upon checking, but was told that should not be enough to make the engine seize. So the mechanic replaced the starter and upon turning over the vehicle the engine began to produce a bad knock and I was told that the engine was needing to be replaced and was going to lock up again if driven. The vehicle is at 70,000 miles so is no longer covered under the factory warranty and the extended warranty may not cover it so I'm at a lose at the moment. I find it really hard to believe that after all the research I've done on this engine problem and seeing all the people with the same situation occurring that a recall has not been issued on this year.
