Noises During Shifting problems of the 2014 Nissan Versa

I purchased this vehicle from a Nissan dealership in November of 2018. I noticed at the end of January 2019 that the vehicle was having problems 'shifting' gears, accelerating and the rpms would rev, but the car would not function properly. It tugged, and jerked. I took it to the same dealership's service department in February 2019. I was advised that there were no error codes showing up and they could not duplicate the problem, and that the vehicle was and I quote 'totally fine and safe to drive. Then on March 28, 2019 the vehicle started having worse acceleration issues, this time also at slower speeds. The vehicle would stall out and not accelerate after coming to a stop at a stop sign or light. No error lights were present. It would keep jerking, and tugging. A lour whirling noise was also heard. I had it towed to the same dealership, the next day they informed me that the transmission was blown, and would need to be completely replaced. It would cost approximately $4200 to repair. I paid $5600 cash for this vehicle in November 2018.

Started the Versa after being parked for at least 30 minutes and was exiting a shopping center. Exit requires driving up a significant incline to access busy three lane road. At the crest of the hill, during pause waiting for access point to enter traffic, Versa would not move even with excellerator depressed. Tried several times and Versa instead rolled backwards, gaining momentum while going down hill backwards. Brakes failed, pressed all the way to the floor and would not stop car until a curb was hit. Later, exiting the same location and crossed in 2 lanes, the Versa running but the transmission would not move the car. Zero rpms. Car stopped dead in its tracks and would not move even shifting gears trying anything and everything to get out of the oncoming traffic. After several attempts to move the car, the Versa died. Versa then would not start and only made 'clicking noises'. Five people in the car all at risk during this serious drivability concern. Once able to restart the car, the trans and engine sinked and Versa then drivable. Exited the roadway. Drove the vehicle in less populated area to the dealership. This all following a complaint to the dealer in may that the transmission was making unusal noises which they claimed was normal for the 2014 cvt.
