“Two months ago I had a sudden acceleration event in my Lexus LS430, 2005. I was ina museum parking garage, my wife got out, I needed to reposition to not be 'on the line'. I backed up, pressed the gas very lightly and the car accelerated out of control. I slammed on the brakes and was able to halt it one-two inches from the wall. Initially, I blamed myself but then thought it might have been my floor mat and removed it. My wife remains terrified to this day. …”
NHTSA complaint #10303764, filed 2010-02, 30,000 miles“On sep 17, 2009 as I left a gas station the Lexus LS430 year 2005 accelerated and I was only able to avoid the cars in front of me was to swerve to the right and jammed of the brake with both feet. Unknowingly I ran into a telephone guy wire and the only damage was superficial ($3300.00) to the right front light and bumper. For the last few months I have been trying to figure out what could have possibly gone wrong. I notice the accelerator pedal appears to momentarily stick. Usaa fixed the auto and though I wondered what had happened I did not report the accident until now.”

NHTSA complaint #10145363, filed 2005-12, 4,600 miles“As I was driving along the road, two miles from my house in a residential area. The car suddenly and drastically began to accelerate. I remember vividly pressing the brake pedal multiple times but it failed to decelerate the car at all. Afraid as I was, I ceased to step on the brake or the gas pedal, the car continued accelerating and kept gaining momentum. At that point, I was trying to avoid hitting the cars in front and incoming cars from the other direction of the road. I drove for about a half mile on and off the right side curbside, as clipping mailboxes along the way. …”
