NHTSA Complaint #11451268 — 2020 KIA SOUL

The supposed remedy for SC209 on my vehicle only included a test as per the Kia certified techs on 10/27/2021. In June 2021, while the vehicle still had warranty remaining, my Kia soul stalled out at a traffic light near Towson, Maryland. The check engine light illuminated, as well as oil pressure. I brought the vehicle to Kia of Westchester (PA) to remedy the issue. The determination at the time was a cam shaft pin had broken, and that was the cause. They replaced the pin, and I continued to have the check engine light come on. I took the vehicle back on 6/17/2021 with the same issue of check engine light and stalling. They reported no issue, and no light after they had cleared the code. I noticed by early autumn a strange knocking sound at low RPM and the check engine light re illuminated. This was the time frame that the "test" for the SC209 recall was "performed" and the Soul apparently passed (no explanation was given for the parameters at the time). The techs suggested the check engine was now due to a faulty catalytic converter (10/27/2021 mileage 107564). I was also told that the sound I was hearing at low RPM was "engine pinging" and I needed to use higher octane gas (not manufacturers recommendation). 1/15/2022 My wife was operating the vehicle coming back from work in Philadelphia when the Soul sputtered and died, shutting off the engine and causing check engine and oil lamp to illuminate. At this point, the engine struggled to reach any highway speed, the engine could would rev loudly and clouds of bluish grey smoke billowed from the exhaust. I replaced the spark plugs (2nd time, less then 12k mileage) and all coil packs with OEM parts. I noticed burnt oil on the old spark plugs. I brought the vehicle to Jiffy Lube in Glasgow, DE to perform a full synthetic oil change (recommended, and what I normally do). The vehicle continued to have the same issues, and blow out large blue gray clouds of exhaust.
