It's really NOT a new problem at all, I test drove one back in December and I have already commented that the car do have trouble managing it's weight in the bends, and it starts earlier than 180km/h. Because of the nearly 4000lb of curb weight, it's not a sharp handling car and the only really the car turns so well despite it's weight is the way Nissan tune the 4wd system to aid in turning. But it still have to obey physics and so the computer cannot mask everything.

To me the closest comparison would be like driving a Saleen tuned Mustang, but with more traction.
