Noises During Shifting problems of the 2014 Chevrolet Impala

Tl the contact owns a 2014 Chevrolet Impala. The contact stated that the vehicle did not fully shift out of park. While driving various speeds, the contact heard a loud grinding noise coming from the brakes. There were no warning indicators illuminated. The vehicle was not diagnosed or repaired. The dealer and manufacturer were not made aware of the failure. The failure mileage was 62,860.

June 2016 at 20k miles the car was erratically shifting at 30-35 mph and had a bad smell from the vents. I brought it to bonner Chevrolet who stated they were unable to replicate the issue and it may be due to running too high of an octane of fuel. The issue was not resolved. October 2016 I brought it back to the dealership for the same issue but I also noticed a slight ticking noise. A motor mount was changed but nothing was done about the shifting issue or bad smell. They stated because the car was not giving any codes, there was nothing else they could do about it. August 13 2017 at 25 or 30 mph while accelerating the car violently jerked my son and I forward. It also did this while downshifting. It continued to do this for 5 minutes until it began to no longer shift gears. The check engine light came on. It got to 4500rpm when I pulled over and shut the car off. I turned it back on after a few minutes but the issue continued. After another 5 minutes I got home. Monday 8/14 after arguing with chevy about towing my car since they didnt want to pick it up until 8/17, they agreed to pick it up that day 8/14. They also stated I would get a rental as long as it was determined the issue was a failure on behalf of chevy and not myself. Tuesday 8/15 came with no update from the dealsership. Wednesday morning 8/16 I called for an update and was informed the car had "internal engine failure". The service rep paul at valley Chevrolet refused to give me the code the car was giving for the internal engine failure. He refused to give me a rental because the car has over 36k miles. I informed him this is conflicting from what I was told on 8/14 by customer service. He said that if I did not want the car fixed, that he could leave my car outside. No call back yet from customer service as the rental and transmission replacement should be covered under the powertrain warantee.
