Japanese to English Tech/Engineering Automotive / Cars & Trucks

This is taken from an Excel sheet related to auto safety.

I currently have "Control must ensure vehicle behavior is not jerky (due to hunting)"

I think this translation could be wrong; sometimes multiple が’ｓin a sentence cause my brain to overthink as to what is affecting what.

Side question - Another reason I get confused is that at other times the document uses ”をギクシャクさせない" with the rest of the sentence being the same - is this basically saying the same thing as the がぎくしゃくしない？
