Lexus LS460 Steering problems by year

no dealer has facilities to do this. The 2nd incident occurred on a hill at the intersection of willard & parnassus in san francisco on 3/14/14. I had made a u-turn to enter a parking space on willard and was facing downhill. When I put the car in reverse it rapidly rolled forward which is not expected in an automatic. I submitted video evidence of this to lexus and this problem was reproduced by freeman lexus in santa rosa which, however, has no way to fix the problem, and lexus refuses to do so though this, too, could be a safety hazard. This 3rd incident occurred on 4/14/14 when, at woodland market in ross, I put my car in reverse and the rear view camera did not come on. I put it back in park and then back into reverse and the camera still did not come on. I made a video of this and sent it to lexus and went to lexus of marin to show them the problem. They would have to take the car but I could not give it to them and explained this would not occur again if the car was turned off and started again - which I showed them to be true. This also could be a hazard but freeman lexus cannot reproduce this and lexus absolves itself of any responsibility. Lexus, in fact, tells me if the car works "as designed" based on what the dealer can find they will not fix or investigate the issue even if safety is involved. This violates the toyota doj agreement. *Tr
