It is possible to simultaneously depress the gas pedal when braking, this causes sudden uncontrollable acceleration I reported the incident too Toyota and requested upgraded ECU software that disables the gas pedal while braking Toyota refused to provide a simple software fix my wife is a witness.

We were proceeding to make a R.H. turn from on two lane road to another in a 2003 Lexus Gx when the accelerator stuck and ESC completely failed. Although I pushed transmission's lever in neutral. The rear end skidded outward and no ESC or ABS was evident. I steered into skid and then steered into ditch to avoid offset collision with oncoming traffic. And skidded into ditch on opposite side of road. Severe concussion and amnesia for driver as dead slammed into driver's window. Passenger suffered left leg injury. I reported two prior incidents to NHTSA Jan 9, 2010, etc and no response. Now I am going public and to senator rockerfeller that NHTSA is totally unresponsive.

In 2007 or 2008 the accelerator on my Lexus gx 470 stuck in the wide open position. I had floored the accelerator to pass a truck and when taking my foot off the accelerator the car would not slow down. I was able to apply the brakes with much effort and turn of the ignition. The floor mat was not part of the problem. I then restarted the car and it drove normal. I took the car to the Lexus dealership where I purchased the car new, which is Lexus of mishawaka, Indiana. They inspected the car and said they could find nothing wrong and that it was probably the floor mat. It was not the floor mat. I traded the car in at Lexus of mishawaka in November of 2008. I no longer own the car.

I was traveling West on a two lane paved road (sutton road) near sutton school. Weather was snowing and road conditions slippery when my accererator failed to return to idle position. I applied brakes as I was approaching a vehicle in front of me traveling in the same direction. The electronic stability control failed to maintain straight direction as per design intent and manuals. Front began sliding to left and rear of vehicle began sliding to right. I ncreased brake pressure and steered into th skid, to the right. I was able to miss the contact with any other vehicles and or damage any property, but did end up sliding into a ditch off of the road. With the impact resulting in the death of my service dog. As I am handicapped. No damage to my vehicle, but no I am virtually immobile with the loss if my dear service dog.

The contact owns a 2003 Lexus GX470. When she attempted to drive the vehicle into a parking space, it suddenly accelerated and crashed in to a parked vehicle. A police report was not taken and there were no injuries. A local mechanic was unable to diagnose the failure. The failure mileage was 105,000 and the current mileage was 130,000.
