NHTSA Complaint #11589005 — 2016 KIA SORENTO

My 2016 Kia seronto was fine wasn’t throwing any codes not even the code that tells me my oil is low. But always kept it changed and maintained never had a problem with it only the code that says 02 sensor then I started having an exhaust leak near my engine it was getting so hot to the point it was catching my carpet inside my car on fire so I had to pull up the carpet that never bother me or made an issue for the car I was driving and it started knocking like a rod knock I check the oil and there’s oil in it with no metal shavings or a creamy color to it. Car still starts gets louder when the rpms go up so I’m just a bit confused to what happened when I kept my oil changed and my car never warned me of any problems and only thru a code for the o2 sensor I seen the recall for different Kia for the rod knock sensor detection so could that have happened to my Kia since it just messed up without any time of warning please let me know at [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
