2017 Kia Forte cruise control problems

I have had my 2017 kia forte for 3 months and in the veey beginning it drove fine. Recently the car has become very sluggish and became increasingly hard to accelerate. I noticed it but brushed it off. This past weekend I let someone drive my car and they complained about how hard it was to accelerate. That's when I knew that it wasn't just me.

Tl* the contact owns a 2017 kia forte. While driving at any speed and attempting to accelerate or switch gears, the engine hesitated without warning. The failure recurred several times. The failure recurred. The manufacturer was made aware of the failure and stated that there was no failure with the vehicle. The contact was provided a case number. The failure recurred and the contact called the better business bureau where an attempt was made to mediate between the contact and the manufacturer.
