2011 Toyota Camry drivetrain & axles problems

Tl* the contact owned a 2011 toyota camry. While the contact's wife was attempting to drive the vehicle in reverse, it spontaneously accelerated and crashed into a stone wall. The driver sustained injuries to her wrist and ribs, which required medical attention. There were no warning indicators illuminated. The air bags deployed. A police report was filed. The vehicle was towed to an independent lot and deemed destroyed by the insurance company. The dealer was not contacted. The vehicle was not diagnosed.

Upon doing research, I've noticed there are several complaints concerning the transmission on this vehicle. When my wife and I first bought the vehicle, I noticed the the vehicle would hesitate when shifting gears. Sometimes when I would drive the vehicle, it would rev up very quickly before it changed out. Just recently, it begun to rev up more often before it shifted gears. It did that for a few days before it wouldn't shift gears at all after 40MPH.then ultimately, it wouldn't change gears at all.
