“My car (insured) rear ended another party at less than 10 miles per hour. The pre-collision system that is part of my car never became active in my car and so I rear ended the car. Lexus inspected my rx-350 and have an unacceptable reason that it will not work, unless there is a noticeable speed difference between my car and the car ahead of me. The car was the problem and it did not work and so I rear ended the previous car. My lights were also broken and had to be replaced. Some electrical wiring rework was also done.”

“While driving home, I stopped the car at the entrance to the drive way at the mail box by applying brake .the car came to a full stop. I shifted the gear ( automatic ) to park to get out of the car to pick the mail. As soon as the gear was in park, the car accelerated uncontrollably, inspite of hard breaking. I could feel the ABS system being activated by the way it feels on the break pedal. The car hit the side of the house and stopped. This vehicle has built in pre collision system. After notifying the insurance company the car was towed to a body shop where it is being worked on.”

“Often times I press the gas pedal to accelerate a little and it's like you let off the gas entirely. You then have to aggressively press the pedal down to which it reacts wildly. Sometimes you barely touch the pedal and it takes off but most times you get little to no response. Acceleration does not react linear in conjunction with the gas pedal. A safety issue when you try and enter into traffic.”
