I have a. 2006 Five Hundred, with 50000 miles ,which I am assuming is close enough for this category forum...I am noticing a recurring issue of possible engine surge. It is noticeable when I pull into a parking situation. I notice a lurch or jerk forward as the speed comes to less than 5 mph and the car is being braked. I have not noticed it as I coast to a near stop and then apply the brake. One last factor, I am in the process of straightening the car in the parking slot.
I have not check the Ford Motor web site for possible recalls.
thanks for the replies, J
