NHTSA Complaint #11513235 — 2020 KIA SOUL

I was driving down the road when all of a sudden the engine started to sputter and shake violently. I couldn't get it to accelerate. I pulled the vehicle to safety and shut it off. I looked under the hood and saw or smelled nothing unusual. I restarted the vehicle and it ran okay. I went immediately to a Kia dealership. I was told that if it was running okay to make an appointment for the next day. I did. The battery was changed out and I was told it was fine. It is not. The same thing happened again, several times. I am being told that if they can't duplicate the problem, they can't fix it. This problem is very unsafe given the entire vehicle slows to an almost stop, even on the highway, at times. I have researched this and it is a common problem with this engine. Many have caught on fire. Kia sent out to the dealerships a Technical Service Bulletin, Number 203, on March, 2019, for Model 2020My Soul(SK3) 1.5T, addressing this problem, yet the local Kia dealer does nothing about it. I was told the recall on this vehicle for the Improperly heat-treated piston oil rings was taken care of but I have to wonder.
