I have been having problems with 17 Pacifica do 9jng a hard shift at 15 miles per hour, feel like I'm being rear-ended when it shifts. Took it to dealer days it was an update issue. They updated it, but it is still doing it. I'm taking it back in Monday. I just hate that my less than 2 year old car is already having transmission problems and I dont feel safe when traveling far from home. Anyone with similar stories? I have seen some past threads but nothing recently.
