2011 Nissan Cube drivetrain & axles problems

When attempting to accelerate from a complete stop our nissan cube intermittently accelerates very slowly and is not responsive to depressing the gas pedal. The vehicle will then lurch forward as though it is down shifting and takes off. This has been reported and investigated by the dealer 3 - 4 times (first report in july 2012) with the most recent visit (oct 2014) resulting in a replaced transmission.

My 2011 nissan cube was being driven to work on the interstate. I pressed on the gas and the car did not move, all of a sudden it lurched forward almost causing me to rear end the vehicle in front of me. I took it to the dealership and I was told I needed a new transmission on a 2011? The car is barely four years old. It is outside of warranty and it is costing me $3700.00. After researching, I see that they have had problems with these transmissions and have extended warranties up to the 2010 models.
