I was driving to the gym at 5:30 am on July 3, 2008 in my Lexus is 250. I pressed on the accelerator after a light turned green and the car took off, speeding faster and faster. I tried using the brakes and that didn't help. I engaged the emergency brake and that didn't work. My car continued to go faster and faster. I was scared to death and didn't know what else to do. Thankfully there was very little traffic due to the time of day. I pressed the electronic ignition button and that didn't work. I was preparing jump out of the car that was now speeding at about 60mph or so when I thought to put the car in park. That finally stopped the car. I jumped out of the car and a pedestrian lent me his cell phone to call my husband. The car was in the middle of the street "bucking" ( the engine was still revving and the car was in park - still running) for about 10 minutes until my husband arrived. He opened the door, checked the mat - it was not on the accelerator pedal. He turned off the car and we called Lexus to have them come tow the car to the dealership. The dealership (Lexus of watertown, MA) checked the car and told me there was nothing the matter with it. That I was the problem, that the mat was on the accelerator. This was not true. Both my husband and I saw the mat was not on the accelerator. They completely dismissed the entire event. I almost died driving their car and they blamed me (all the time knowing about the problem).

Car unexpectedly decelerates, engine shakes and "check engine and vsc lights" come on. After a short rest the car would start and the problem would repeatedly re-occur until I arrived home. Lexus service has not been able to fix the problem and I do not feel safe driving the car.
The contact owns a 2008 Lexus Is250. While driving approximately 5 mph into her garage the vehicle accelerated into the refrigerator door and the garage wall after she applied the brakes. The dealer advised her to take the vehicle to the collision shop to be repaired but the dealer never checked the vehicle. The manufacturer was not notified; however, the contact received a recall notice but didn't indicate what component it was related to. The VIN was unknown. The failure mileage was 7,000.

Wife was driving on the interstate with the cruise on doing about 65 mph, and she decided to pass a truck. She accellerated slightly, and the car suddenly "floored" to over 90 mph and the rpm's went all the way up. She truned off the cruise, but it wouldn't slow down. She tried to brake, but the engine was still reving at the highest speed. She forced herself off into the grassy median and sat on the brake until she could jam the transmission into park and turn off the engine. Veh towed to Lexus dealer. Tech couldn't figure out what was causing this, but after talking to Lexus headquarters, they found that the rubber car mat and the back of the accellerator somehow connected and forced the car to be "floored". You could not tell by looking at the mat that it was connected to the accellerator. My wife would of died if there had been another vehicle close to her. No accident or injury. I have no complaint with the dealer. They did everything they could to help.
