NHTSA Complaint #11566711 — 2017 KIA SORENTO

My car cut off on a major highway on 12/13/2023, but luckily i was able to pull off an exit. My car stalled and wouldn't crank. Called someone out who did a diagnostic and said it was for my knock system(P1326).I was able to get it home and black smoke was coming from my tail pipe. I haven't driven the car since then. I went to Kia on 1/15/2024 to get recalls done and also inquire about my check engine light. Kia never did a diagnostic test for the check engine light. They only did recalls and sent me on my way. I called Kia and made another appointment to get a diagnostic test done on 1/20/24 and then i was told that i would need an engine replacement and my warranty doesn't cover it. Then he gives me a printout of codes which states pending and told me that p1326 code didn't show so therefore it's not covered. He tells me that it's a blockage on cylinder 4. I told him when i came to you a few days ago, i asked about my check engine light and i was ignored. Upon pulling out of Kia parking lot, i noticed a large cloud of black smoke that i didn't originally see when i brought it in and it was so cloudy that other cars had to stop because they was unable to see. Luckily i got it back home and parked it cause it's very unsafe for me to drive even tho Kia saying i can still drive it. My car burns a lot of oil even tho i don't really drive cause i work from home but evidently, every time i get oil checked it's always low so i was getting it topped-off every other month and was told by a mechanic that Kia engines burns a lot of oil and the engines no good and now look, i'm needing a new engine and i just purchased this car in 2020 and i see it's been so many services done to it before i purchased itMy car only gets up to 50mph since the engine light came on so prefer not to drive it anymore.
