2005 Toyota Prius drivetrain & axles problems

My daughter was driving our 2005 prius at about 30 miles an hour at approximately 3pm when she saw a truck stop approximately 300 feet ahead of her. She applied the brakes but the prius did not stop and collided with the truck causing a total loss of the prius. The road surface was wet from snow and the temperature was approximately 34 degrees. Although the car was heavily damaged the air bags did not deploy. This crash could have resulted from a brake problem or unintended acceleration.

Tl* the contact owns a 2005 toyota prius. The contact stated that the vehicle failed to start. In order to start the vehicle, the emergency brake had to be engaged. The contact also stated that the headlights failed intermittently but would function normally after attempting to activated them several times. In addition while driving at various speeds, the transmission would erroneously shift into neutral and all of the contact's attempts to shift back into drive failed.
