NHTSA Complaint #11501557 — 2017 KIA SOUL

On the day after Thanksgiving 11/26/22, I was driving this vehicle home via the interstate when it began to decelerate without any warning. I pressed to accelerator and the car began moving slower and slower. I pulled off at the nearest exit and as I was exiting the interstate, the car almost completely stalled on me, idling very rough at the red light. While waiting for the light to turn, the engine light illuminated and began flashing. I live a mile from the interstate but I was able to make it home. I was very nervous because the car jerked and shuddered like it was about to die on me in the middle of the road. The next morning, I took the car next door to my residence and has some diagnostics ran on it. I was told that the car needed new spark plugs and coils. After paying for this service, the car still ran poorly as describe above so I took the car back. I ended up having the car towed to the nearest dealership and it was determined that I needed a completely new engine. I thought to myself "well at least the powertrain is still under warranty since I am the original owner and have kept up with timely maintenance. My warranty was denied due to lack of one missing oil change invoice that was done at the dealership back in 2018 at 18,000 miles. Somehow this missing oil change was missing from the dealership's records as well. I am good at keeping up with the maintenance on my vehicle, especially one that i bought brand new back in 2017 that's still under warranty but somehow, it was still denied. I decided to pay out of pocket to get the car fixed. The cost was over $6300. I picked the car up today 01/12/23. After driving approximately 15 miles, the car began to make a ticking sound at which point the check engine light came on again. Obviously the car is not fixed.
