2015 Chrysler Town And Country cruise control problems

Tl* the contact owns a 2015 chrysler town and country. While driving approximately 5 MPH, the vehicle independently accelerated and crashed into a cement wall. A police report was not filed. The air bags deployed. The contact sustained bruises and burns from the air bag on her leg. Medical attention was required. The contact drove the vehicle to an independent mechanic where it was diagnosed that the bumper, air bags, and other unknown parts needed to be replaced. The dealer was not contacted.

Cruise control does not hold a steady speed on hills, even small hills like we have in michigan. The speed drops 3-4 MPH as it goes uphill (very unsafe for those traveling behind us), then it downshifts and accelerates 5-7 MPH (very unsafe for those traveling in front of us). Every time the vehicle has been in the dealership I mentioned it. I called chrysler (I taught automotive so I have graduate connections at chrysler). Their answer is that is normal.
