2012 Jeep Grand Cherokee body & structure problems

On june 24, 2016, between 1:30 pm and 2 pm, I was driving from brentwood ca to vallejo ca on hwy 780 w and after turning a curve on the freeway which sloped down towards curtola parkway, I applied the brakes at about 30 miles per hour after I emerged from the overpass which was at least 5 car lengths before the cars ahead of me which was stopped at a red traffic light. However, the jeep continued to roll even though I pressed on the brakes to the floor board.

When I was driving straight down the street going about 35 MPH, I heard a loud explosions like noise and then my jeep became disabled. I took the vehicle to the shop and I was told that the vehicle was totaled and that the body and frame of the vehicle had completely separated itself from the vehicle. I have been told by several people who have inspected my vehicle including the dealership and insurance company that this is a manufacturer defect to my vehicle.
