2013 Chrysler Town And Country drivetrain & axles problems

Tl* the contact owns a 2013 chrysler town and country. While the vehicle was in the park position, the vehicle independently rolled and knocked the contact to the floor. The front driver side tire ran over the contact's left leg and continued to roll down a hill until it stopped at the bottom of an embankment. The contact sustained tissue and nerve damage on her left leg, two torn rotator cuffs on her left shoulder, and severe bruising on the entire left side of her torso that required medical attention.

May 27 I floored the accelerator to pass a slow truck at 57 MPH let up on the pedal but the van continued to accelerate (the vehicle had previously had a transmission software update so I changed the econ o button and also kicked the foot pedal) at this time the vehicle was showing a mile or two from 80 MPH. At witch time I held the brake and pulled off the road.there was a large red throttle body light on. When I turned the engine off. I decided to wait as the brakes smelled very hot.
