“I wish to inform you about a serious incident that occurred on september 21, 2013 while driving my Lexus 350 awd 2012. I was parking the car. My foot was on the break pedal and I was about to reverse when the car suddenly self accelerated and went up a 45 degree embankment. The car drove over very large boulders that were at the head of the parking space. The underbelly of the car rammed into a very large boulder that raised the left rear wheel off the ground and stopped the car from continuing up the incline. …”

“On 6/25/2012- at 7:10 am, I was pulling into the parking spot for my vehicle in my hospital parking lot for a scheduled surgical case, where I work as an ob/gyn physician/surgeon . As I turned to the parking spot at the usual, approximately 2-4 miles /hr speed ( the speed at which normally one parks the car), I noticed that my accelerator pedal did not bounce back to its original position as it normally should or would. Then my rt foot was on the brakes to just stop the vehicle in my parking spot. …”

“I had an accident with my 2012 Lexus on 5/1/13. I pulled out of a gas station unto the road and stopped at a red light behind a car carrier which was stopped already. When I stopped, my car accelerated and hit the back of the truck. When the police came, they cited me because I hit the truck. When we brought the car to the repair shop and I explained what happened, he said he had a similar case a month before. With that, I searched google and realized that I wasn't loosing my mind and that my car accelerated unintentionally. …”

“While pulling into a parking space at approx. 3 MPH and being less than a foot from where I would have fully stopped, the vehicle accelerated uncontrollably as the engine raced at a very high RPM. I was able to turn my wheel quickly to the left to avoid hitting the vehicle in front of me. At that same time with my foot that was already on the brake and I braked very hard, then shifted into neutral and the vehicle stopped. I had a small piece of wood flooring on the back seat which came flying to the front and cut the passenger side dashboard. …”

“First part of complaint just in case it did not go thru the first time. Dear sirs, I'm writing to you on behalf of the owner of this vehicle. They have contracted me as a vehicle accident reconstructionist in puerto rico. I need to know if you have made any inquiries in the fuel delivery and propulsion system. My concern is that this toyota, Lexus and honda vehicles that I know of so far, are having some kind of sudden acceleration issues and the computer does not catch the problem. This acceleration surges that I have found out about, all have occurred around high electricity areas. …”
