MY 2009 TOYOTA SIENNA ACCELERATED UNEXPECTEDLY AFTER THE CRUISE CONTROL WAS SET. THIS HAPPENED 2 DIFFERENT TIMES WHILE MY WIFE WAS DRIVING IT. I WAS NOT IN THE CAR. MY WIFE HAD TO IMMEDIATELY PRESS THE BRAKE PEDAL TO RELEASE THE AUTO CRUISE. AFTER THE BRAKE WAS PRESSED THE AUTOCRUISE RELEASED THE ACCELERATION. OUR CAR IS NOT IN THE RECALL LIST I THINK.

I RECENTLY DROVE A RENTED 2010 TOYOTA SIENNA VAN, FROM ALAMO RENTALS IN SAN ANTONIO TEXAS. I FOUND THE CRUISE CONTROL SYSTEM A BIT QUIRKY AND A BIT STARTLING AT FIRST. ONCE THE CRUISE CONTROL WAS SET TO 70 MILE PER HOUR, THE SYSTEM OPERATED FINE AND MAINTAINED THE SET SPEED. HOWEVER, ONCE EVERY 3 OR 4 TIMES THE CRUISE CONTROL WAS DISCONNECTED USING THE BRAKE PEDAL, THEN USING THE RESUME FUNCTION OF THE CRUISE CONTROL, THE VEHICLE WOULD ACCELERATE RAPIDLY PAST 75 MILES PER HOUR. ONCE I DISCONNECTED THE CRUISE CONTROL AND RESET THE DESIRED SPEED, THE CRUISE CONTROL OPERATED NORMALLY. THIS SEEMED TO BE A PERSISTENT BUT INTERMITTENT ISSUE. ONCE I WAS AWARE OF THE POTENTIAL FOR RAPID ACCELERATION AND SPEED OVERSHOOT, I WAS ABLE TO ANTICIPATE AND CONTROL THE VEHICLE FROM RUNNING AWAY. IN LIGHT OF ALL THE ISSUES CONCERNING TOYOTA PRODUCTS, I THOUGH I WOULD BRING THIS TO YOUR ATTENTION. DRIVING CONDITIONS AT THE TIME OF THESE INCIDENTS WERE DRY CONCRETE ROAD, 7 PASSENGERS IN THE VEHICLE, HIGHWAY SPEED OF 70 MILES PER HOUR, OUTSIDE TEMPERATURES WERE BETWEEN 34 DEGREES F TO 70 DEGREES F. HIGHWAY WAS STRAIGHT AND LEVEL. *TR
