2005 BMW 545i Q&A

2005 BMW 545i Question: What causes my car to jerk while I'm driving?

It jerks every couple of seconds when I'm driving. It used to do this several months ago and then it stopped. Now, it's doing it again. Any help would be greatly appreciated. I'm constantly having to have repairs done to this car. -
