The hard pull to the right on acceleration is happening because a
front wheel is spinning a bit. The reason you don't notice it is
awheel spinn is because the RT4WD kicks in and still accelerates the
car forward. You will notice it worse on damp and wet days, and you
should notice it less as you get used to the car.
Even my wife, Ms. Leadfoot, has almost stopped after 4 months. But
she was used to a 2 ton Range Rover that took a lot of gass to get
moving off the start.
