NHTSA Complaint #11523866 — 2018 KIA SOUL

I bought my kia soul with about 86000 miles on it. It used to be a rental before. It was well maintained, oil changes when needed, new tires, etc. I was driving back from my family's going about 70 up and down mountains when the engine made a ticking sound and it started to slow. We were still about 2 hours from home. We did make it back due to using the manual drive. We were planning on taking the car in the following weekend for an oil changed. When Tuesday came around my partner had the car and he was driving 70 on the freeway when it started to slow again and he made it to an off ramp where it shuddered, shot smoke out the back and died. We got a tow to pep boys and they let us know that it ran out of oil (althought we checked before me left my family's) and the engine no longer works and to replace the engine was going to be $15,000. There were no warnings at all to this.
