NHTSA Complaint #11607802 — 2016 KIA SEDONA

My van has 126k miles and regularly gets an oil change. We are the original owners and haven't had any issues with it either. As I was driving up hill, I realized I was losing acceleration power. Where i should be going faster than 65 mph, I was barely going 40. The outside weather was around 100 degrees and I'd already been driving for an hour. I glanced at the other things on my dash. My coolant meter was straight up, so that didn't flag an issue either. I started to switch lanes to get to the shoulder. As I did, my check engine and oil light flashed on for my van to then turn off. When I tried to start it, it clicked with no ignition. I don't know if there was smoke behind my car or if it was me turning up dirt when I pulled over, but there was a pop sound. It wasnt like a backfire. When i got out, I could smell a burned smell outside my van. There wasn't anything dripping from the bottom of my van either. A person who stopped to help checked my battery and it was fine. When it got towed to my house ($400), another person was surprised with a gummy residue in my oil tank. There are holes punched all over the bottom of my engine, but there is no oil anywhere. They said the engine should be covered with it or there should be oil splatter somewhere. Talking with the KIA dealership, they said it 75% doesn't sound like a recall, and I would have to tow it there at my expense for them to check, too. How can there be no warning of any issue if this isn't tied to the recall? We are now debating on if we want to spend another $400+ to tow it and then again to bring it back if they aren't going to cover the cost of the engine.
