Truck lunges forward sometimes. It will work properly most of the time and then after stoping , when you tramp on the gas it will hesitate then lunge forward. As I said most of the time it works properly. I consider this a very real hazzard, has been doing this for months. One day at my golf club while pulling into my parking spot,a tight fit, I had to back up to get into my spot. When I tried to go forward it had about a two second hesitation then squealed the tires. I have witnesses. My dealer says everything with the truck is normal after they inspected it . The internet is full of the same thing from other owners of the same truck.
