NHTSA Complaint #11480137 — 2016 KIA SEDONA

The vehicle while driving and accelerating at any given time stops accelerating even when you are pressing the accelerator all the way in. Usually occurs when I am on highways or normal roads. No check engine light or indication of failure has come up to retrieve a code and be able to diagnose the issue. I took the car to the KIA dealer service center near me, but they weren't able to fix anything, because no code came up for the issue. The not responding to acceleration has occurred multiple times for a while (Aprox. 4-5 times over the last 6 months). I am concerned as it may seem the engine is trying to stall or stop working in the middle of the road. The safety of my family and others driving behind me can be at risk because if it stops responding to the acceleration, I may need to pull to the side or may not have sufficient time to do so, causing an accident. I communicated with Kia, and they open a case report, but they advised me to submit a report to this agency.
