Automatic Emergency Braking problems of the 2016 Subaru Forester

My Subaru Forester is equipped with airbags and Subaru's eye sight anti-collision braking system. On Aug 5th my wife met with an accident while trying to avoid a head-on collision side swiped a vehicle on the right lane which hit the car on the rear side and the impact further changed the direction of her car and she went and hit the steel fence stone pillar on the right side. The frontal collision with the stone pillar damaged the bumper and car engine is dislocated from its position as the frame is deformed and the front tires jammed. The car's famed anti-collision system did not prevent the collision and the air bags failed to deploy. I suspect that there is a serious manufacturing defect that all the safety systems failed in the car, hence I request you to conduct an enquiry while the car is being sent to the repair center to ascertain the right cause of failure.

Context: we were driving on the freeway at ~30-40mph when the car in front suddenly braked and stopped. We hit the breaks at the same time that the automatic brakes kicked in. The car stopped, as needed. Issue: after stopping, we pressed the accelerator to start the car moving again but the car revved instead of accelerating. We pulled off/slowly drifted to the side of the road and turned the car off and then back on before the accelerator started to function. This seemed like an engine problem. Safety risk: during this incident we were stopped on the freeway with no way to accelerate, which was very dangerous. We were lucky to be next to the shoulder lane. Otherwise, we would have been stuck in the middle of a freeway with a speed limit of 60mph. Inspection by Subaru result: "found normal operation on test drive. No current codes or related history codes. Likely a temprary fault under extreme condition. Please monitor".
