2007 Jeep Commander 4X4 electrical system problems

I was driving home from picking up my daughter from a school event when suddenly my car slowed down on its own down to 10 MPH. Then the car completely stopped. On the control console it only read "service park assist" and the drive position controls where all highlighted and boxed out (drnp). I lost all control of the vehicle other than turning the wheel. I tried to accelerate by pressing the gas and it just revved the engine and did nothing else.

3rd row seat belts break and are unusable whenever the 3rd row seats are folded down. The plastic piece is pushed over the metal latching piece of the seat belt. They have been fixed and are now broken again, now the 3rd row seat cannot be used for passengers. Water from rain is coming through the doors, puddling at the base of the door. The jeep was in park, when I attempted to put the car in reverse it would not go, all of the prd were lit up with blocks around them.
