Me ([XXX]) and my 3 children went on a trip from July 25- July 30 to Sequoia National Park & Yosemite National Park. On Wednesday, July 28 around 1:30 pm we were at Yosemite Park and I pulled over to take some photos of the beautiful park(nature). I made sure my children, the car and myself were in a correct parking spot, I put my RAV4 LE in Park position (P) and the car automatically put on the hand break and it makes a loud noise, letting me know it's safe. The RAV4 does not have a hand break like other cars, it only has a small pull button. Anyways the car was in Park position with the automatic break, I stepped out the vehicle and walked toward the front of the car and my RAV4 just stared to roll down and hit a tree. I ran inside the car to stop it but it was too late. The RAV4 had crashed into the tree with my 3 children, they were all asleep when it happen and lucky no one was hurt. The car has a alot of damages in the front area and on the drivers side. The dash was all lit up with messages saying system fail(Pre collision system) INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).
