 When we test drove the vehicle we did not notice the hesitation when accelerating from a stop.  Mainly because we did not encounter any situation where we needed to hurry into or across an intersection.  After purchase and we began to drive the vehicle under normal conditions the hesitation was scary.  The engine RPM was increasing but the car was not going.  The dealer told it that it was the "new transmission".  Therefore, nothing has been done to correct the problem. Pretty junky for such a renowned and expensive car.  Month later the radio dies and the replacement is junky.
