14 reports6 crashes
“TWICE, WITH TWO DIFFERENT DRIVERS, THIS VEHICLE HAS ACCELERATED/SURGED AT A STOP. THE VEHICLE WAS ABLE TO BE HELD STEADY BY PRESSING THE BRAKE AS HARD AS POSSIBLE, BUT VEHICLE STILL SURGED AND TRIED TO MOVE FORWARD. ON THE FIRST INCIDENT, THE VEHICLE WAS PUT IN NEUTRAL AND CONTINUED TO REV MOMENTARILY. AFTER THE FIRST INCIDENT, THE LEXUS OEM FLOOR MAT (STANDARD, NOT ALL SEASON) WAS REMOVED. THE SAME EVENT OCCURRED AGAIN TONIGHT WITH A DIFFERENT DRIVER AND THE FLOOR MAT STILL REMOVED. I AM QUITE CONCERNED THIS MAY BE RELATED TO OTHER TOYOTA RECALLS. *TR”

“THIS HAPPENED WITH NO WARNING. STEERING WHEEL WAS HARD TO TURN COUNTER CLOCKWISE AND WOULD BIND WHEN TURNED ALMOST ALL THE WAY. I TURNED IT ALL THE WAY AND THERE WAS A LOUD "SNAP" SOUND. I THEN NOTICED THE AIR BAG LIGHT CAME ON IN THE DASH. AFTER THE "SNAP" IT WAS EASIER TO TURN THE STEERING WHEEL CLOCKWISE AND COUNTER CLOCKWISE. I DON'T KNOW WHAT IS WRONG BUT WILL TAKE THE CAR TO THE DEALER TO CHECK THIS OUT. *TR”
