2019 Ram 1500 drivetrain & axles problems

Tl* the contact owns a 2019 ram 1500. While the vehicle was parked in a garage, the contact exited the vehicle and it independently accelerated backwards. The contact entered the vehicle in an attempt to stop the vehicle. The contact noted that the vehicle did not drift backwards, but independently accelerated rapidly backwards out of the garage of the contact's residence. The contact was nearly smashed in between the front driver's door and a stone pillar. There were no injuries.

Traveling around 35-40 MPH I was approaching a stopped light. I eased off the gas and when the gas pedal no longer "engaged" the transmission the computer/software disengaged the transmission without my doing. No error was displayed and the knob still showed as in the drive position. As I pressed the gas pedal the rpms rose but because the transmission was in neutral it only revved the engine. I had to pull over, manually place the knob into park, then wait a few seconds then back into drive.
