Ever since the lifters broke in the new vehicle (which the dealer now tells us is a defect in the engine and that the lifters keep breaking; it was not a "bad delivery of lifters" as we were initially told), the car idles very rough and has power surges. Today sitting at a red light with the foot lightly on the break, the car lunged forward against the break during one of the power surges. If we had been closer to the vehicle in front of us, or if we had been up against a cross walk, there would have been a collision.
