The car shut off, i lost control of the power steering and the breaks failed to stop after the computer shut the car off. now they calm the shifter is defective and needs replaced after there computer diagnostic codes failed to detect the problem the first 2 times and a test drive would have told them their was a problem but they refused to do a test drive and relied and faulty computer input. this serious malfunction could have resulted in my injury or death or injury and death to another party. the defective shifter has caused injury to my right knee and tendons. i was in park, a person entered the car. i put the car in reverse and the car shut off rolled down the hill until it stopped by rolling in reverse up a hill behind me. the person refused to be in my car as the danger was obvious to her. the only reason the car stopped was because of the hill. i lost control of the brakes and power steering as the car was shut off. any child or elderly person behind me would have suffer serious injury. the dealership i purchased the car from is refusing to write any of this information down.
