Hydraulic Power Assist Steering System problems of the 1998 Toyota 4Runner

My dauther aged 10 years, was in the rear of the car trying to grab a bag of chips that were in the luggage. When we got rear ended at the highway exit, the back door of the SUV popped open even though the car doors were locked. My daughter was thrown out of the back of the SUV and in front of the truck that rear ended us. Luckily she fell on some pillows that were also flung from the car, thereby reducing her injuries. Also the pickup truck that rear ended us had stopped, so she did not get run over by it. This door should not have opened when it was locked. This is a very serious safety hazard. I have voiced my concerns to Toyota, but there has been no response.

Engine failed twice within two months for no reason. Both times slowing down when going to turn. No one was hurt. /// lost control of 4 runner while slowing down for exit ramp at 35 mph and wet road. Speed was not excessive for conditions. Car spun hit guard rail and then hit and did a 360. 4 days later, dry freeway at 70 mph car suddenly veered to left, spun 360 then into grass median 360 , then 360 back onto freeway and came to stop, only god could have prevented this from being a disaster. Two passengers, no one was hurt. Car covered with grass. ( dot number: tire size: 16 ).
