“As I was parking my Lexus in a parking lot, the car suddenly shot forward, moving over the parking cement barrier and crashing into a wall. The car was repaired. After I received the recall notice from toyota relating to the floor mat issue, I made sure the floor mats were properly attached. This happened only once. I believe that the accident was caused by the floor mat sliding and pushing on the accelerator.”
NHTSA complaint #10319027, filed 2010-03, 3,894 miles“I was pulling up to a red stoplight with a car already stopped at the light. While applying pressure to the brakes, I realized the vehicle wasn't braking correctly. I started applying more pressure until I was nearly standing on the brake pedal when the engine starting revving as if I were accelerating. When I realized the car was not going to stop, I tried to put the car in park. Luckily, I only tapped the car in front of me which startled the 3 children in the back seat of that car. When the driver of the other car and I got out of our cars, we could smell the burning rubber. …”
NHTSA complaint #10559577, filed 2014-01, 93,000 miles“I am driving a car which has accelerated unintentionally three times. I want Lexus to be responsible and find out why my car accelerates randomly and I want them to fix my car. I also want Lexus to admit to this safety flaw. I wish that Lexus would be punished for this serious breach in concern for public safety although that is not my immediate concern. In july of 2009 the car accelerated when the brakes were applied. The car could not be stopped by applying the brakes alone and only stopped when it was put in neutral and hit the car in front of us. …”
