I don't like the fact that I have to put my vehicle in park to switch it from 2wd to 4wd and vise-versa. This is a pain in the butt, especially when there is snow, ice, large amounts of water, or mud. I live in a busy area, and no one is going to stop and wait while you put your truck in the next gear. I also have a problem when it goes back into 2wd there is a grinding noise and then it jumps into gear from 4wd. I haven't seen any similar complaints, it might just be my trucks mileage and age.
