2012 Jeep Grand Cherokee cruise control problems

Tl* the contact owns a 2012 jeep grand cherokee. The contact stated that while parking with the brakes engaged, the vehicle erroneously accelerated and traveled over a bush, a hill, crossed a four lane road and then crashed into a tree. The contact indicated that the air bags failed to deploy and the engine continued to rev after the contact exited the vehicle. The contact then removed the key to shut off the engine. The contact suffered a bruised chest during the incident but did not require medical treatment.

Car lost all power for steering and braking. Car stalled. Was at low speed 5-8MPH turning to the right into a gas station driveway from busy roadway of speeds of 55MPH. Car went straight and rolled to a stop. Grateful was parking lot and ditch in front of me and not the gas pumps or another vehicle as I had no control of the car stopping. I have twice had car to dealer for car going into limp mode. Both in year 2016. Same cylanoid each time.
