A driver of the ls460 series for 16 years. new car every 3 years. my 2007 ls460 was the 3rd car at a red light when it began to accelerate with my foot on the brake. mild 2nd episode 2/7/2009 took all of my energy to hold the car from smashing into the 2 cars ahead of me. shifted in neutral and then park. car finally stopped. took the car to my hospital parking lot. lexus dealer picked-up the car and kept it for 2 weeks. told nothing wrong. was then sent to a hearing with the national center for dispute settlement. the lexus engineer stated that no electrical fault was documented on the computer. the ruling was against me as " it only happened once". i wrote to the president of lexus offering to switch cars with him. no response. i do not allow my wife to drive this car. do not drive with my grandchildren in this car. i limit my driving in this car and stay a great distance behind vehicles in front of me. have called the manager of my dealership 11 times to get a final answer- that "he could do nothing for me". the lexus people are well aware of my incident have letters from them. *tw
