While driving on the expressway over 85 mph I noticed that my car starts to jerk as if there is a fuel cut happening. Have any of you guys had this problem? Its happened multiple times and the dealership cannot figure out whats wrong since they haven't been able to recreate the situation. I've also noticed the car jerk at low speeds a couple times which makes me think its just when I've got the car revving over 3000 rpm. If anyone can tell me what's wrong that would be awesome!
