On numerous occasions the pro pilot feature has malfunctioned and aggressively jerked the vehicle to the left causing us to almost hit the concrete wall divider. The cruise control turns off and on numerous times when trying to change lanes. It drives dangerously close to semis when passing on the left, almost crossing into the right lane. I've taken the vehicle to the infiniti dealership and they tell me they can't duplicate it but don't do anything about it. I had my husband drive it as well and it does the same thing to him.

many times when I am using pro pilot assist it does not brake to point when it is inches of crashing into car in front, I manually have to apply brakes. in addition while being in full automatic mode (hands free mode) it turns off lane keeping assist completely where if the driver was not Able to make split second decisions it would collide with vehicle near it. there is no warning for pro pilot assist mode to be driven below or above a certain speed, Infiniti dealer advised it should not be used for bumper to bumper traffic or within city. but when even using it on highway it sticks to one side of lane and still requires hands on all times but Infiniti advertises it to drivers it is a "safe hand free option" with no warnings. just a awful accident awaiting to happen.
