My car started to jerk forward when I would accelerate from a complete stop. I also had to press hard on gas pedal because it would stick a little. Finally took car in and it was a broken motor mount. Not even 6 months later my car started to make a grinding noise and seemed to stick a little when I would accelerate. I took car back to shop and it is another broken motor mount. After speaking with the mechanic I learned that this is a very common problem in the Pacifica, so much so that the motor mount I needed was on backorder for 3 weeks.
