Hey, recently ive been having this weird slight jerk happen in rpms (2000rpm to 2500rpm quick jerk rev then back down)when driving on the highway. Also VDC off light randomly come on and off as well as the parking brake sensor. Are these related at all?

 

Check attachments for video

 

They could be related and caused simply by low brake fluid. Check and make sure the reservoir is at the full mark,
