While driving, I pushed gas pedal down to accelerate quickly. Engine revved to high RPM and car accelerated and RPM stayed high in spite of letting off of gas pedal. Initially I put car in neutral and engine continued at high RPM. I tapped hard on gas pedal and pedal released. This recurred again when I pushed down on pedal. Appeared to be due to Lexus floor mat catching on bottom of gas pedal. I called Lexus dealer and was told this had never been reported. (I had already had the recalled pedal replacement done). I pulled the floor mat back to prevent the edge catching on the pedal. Approximately one month later the problem recurred--presumably because the mat has slowly pushed forward over the last month.
