    Shuddering in sport mode

    So I have a brand new 2020 ST. It has about 100 mi on it. Today, while accelerating in sport mode, the engine, or transmission, or something was shuddering for about 4 seconds. It only did it the one time and I can't seem to replicate the problem. Anyone have this issue before? NOTE: The dealership prep dept was so "nice" as to give me the car with a full tank of the cheapest 87 octane gas they could get their hands on 🙄. My previous vehicle was a '14 Focus ST, and I know that thing ran like dog poo on anything less than 91 octane. Hoping that's all the issue was.
