Cruise control would not disengage. Instead it accelerated me to 85 mph is rush hour traffic. The car continued to accelerate will out responding to any commands to turn off cruise control. Second time this has happened. It was supposed to be fixed by doing an update to the car. This did not work. The second time I attempted to use cruise control after having had the long block engine replaced due to the oil consumption law suit, the car once again had the same problem with now slowing down. I tried putting the car into neutral and pressing the break. The car was accelerating so fast. The brakes had no effect without causing me to lose control. I was forced to put the car into a ditch at 75 mph. Rather than to rear end the dead stopped 3 lanes of traffic ahead of me and being pinned in by the traffic behind me. Car flipped I now have brain damage and failing kidneys due to blood transfusions
