2014 Nissan Rogue drivetrain & axles problems

On may 10, 2014, I parked my 2014 nissan rogue in my garage. I put vehicle in park and got out went to the passenger side to get my bag on passenger side rear door when the car started to roll backwards. I ran to back of car to stop it. Lucky for me I wasn't behind the car when it started to roll back. I stopped it enough before it hit the decline in my driveway and ran to drivers side and jumped in and hit brake. Moved car back into garage and put blocks behind the tires.

While driving on an interstate, my 2014 nissan rogue would rev and the rpm's would surge unexpectedly and without warning. While driving it would randomly jerk, shudder, and hesitate. We experienced a sudden loss of acceleration leading premature transmission failure. My check engine light did not come on until the car lost the acceleration capability. This put us in great danger being that we barely made it onto the side of the interstate.
