My vehicle steering/control has frozen a few times in the past 18-24 mos. This happens for me in wet conditions at slow speeds while trying to turn, usually to the right. The car also seems to slow on its own and pull to the side at these times. This has also happened while reversing out of a parking spot. I do not recall seeing any lights engage but I am more focused on steering the car safely and exterior factors at these times so I haven't noticed the dashboard. It feels like the power steering fails, and I have no control. Thankfully, I have not been moving at high rates of speed, nor been in a position to go into the lane of on-coming traffic or had someone in a lane near me, and have been able to hold in position or manually turn as much as needed. Steering seems to return once the turn is complete. I have been fearful of hitting someone or being hit from behind each time. My mechanic has been unable to recreate the experience and was unable to suggest a direct answer. I see others have had similar experiences and the same lack of answers from even Toyota. Having come across this website and seeing responses here to this exact problem I have had, I am hoping for more information or a recall soon!

The vehicle stability control system randomly engages and activates the brakes without cause. This can happen on a gentle curve going under the speed limit. It is very scary and I am afraid it is going to cause an accident. Internet research shows many owners with this issue and no information on the cause or a fix

VEHICLE SPEED CONTROL
While driving vehicle on dry, non slippery roads with slight to moderate curves, vehicle illuminates Traction Loss light, sounds alarm buzzer, and at times applies brakes and dethrottles engine, even when no loss of traction has occurred. This happens while driving on straight roads with slight unevenness. Had to disconnect wheel speed sensor harness to disable ABS/VSC system. When this happens, the vehicle automatically applies brakes to certain wheels and dethrottles the engine, this can pull the vehicle to one side sharply and can cause an accident.

THIS HAPPENS WHEN THERE ARE NO PROBLEMS WITH THE DRIVING CONDITIONS. THE SEVERITY OF THE BRAKING AND LENGTH OF ALARM VARY. IT IS ESPECIALLY PROBLEMATIC ON TIGHT TURNS. IT DOES NOT MATTER WHETHER YOU ARE GOING UPHILL, DOWNHILL, OR TURNING ON A FLAT ROAD. WE DO NOT KNOW WHAT IS CAUSING THIS UNSAFE ISSUE. WE HAVE TRIED TURNING OFF THE TRAC. IT MADE NO DIFFERENCE.

THIS AFTERNOON I ENTERED THE HIGHWAY AND WAS GOING ABOUT 60-65 MPH WHEN MY CAR SUDDENLY STARTED ACCELERATING ON ITS OWN, I REPEATEDLY DEPRESSED THE BRAKE, EVEN STANDING ON IT IN AN ATTEMPT TO SLOW THE CAR. THE CAR WAS MAKING A REVVING SOUND AND THE BRAKES WERE DOING NOTHING TO SLOW THE CAR, IT JUST KEPT ACCELERATING. FINALLY, THE BRAKES SEEMED TO ENGAGE, THE REVVING STOPPED, AND THE CAR SEEMED NORMAL AGAIN. I PULLED OFF THE HIGHWAY AND CALLED AAA TO HAVE THE CAR TOWED TO MECHANIC. CAR HAS ABOUT 105,000 MILES ON IT AND IT'S BEEN VERY RELIABLE UP UNTIL NOW. I WILL REPORT TO TOYOTA AND I WILL NOT DRIVE THIS CAR AGAIN, MUCH LESS LET MY CHILDREN RIDE IN IT.

ON MARCH 13, 2015 DRIVING ON I-95 SOUTH IN A 2006 TOYOTA SIENNA VAN THE CRUISE CONTROL WOULD NOT DISENGAGE WHEN THE BRAKES WERE APPLIED APPROACHING AN EXIT RAMP. THE VEHICLE WOULD NOT SLOWDOWN IN SPITE OF PRESSING THE BRAKE PEDAL AS HARD AS POSSIBLE. MOVING THE CONTROL LEVER FORWARD TO DISENGAGE THE FUNCTION WAS ALSO NOT SUCCESSFUL. THE EXIT RAMP WAS INCLINED SO THE CRUISE CONTROL ACCELERATED THE ENGINE IN AN ATTEMPT TO MAINTAIN OUR SPEED AT 70 MPH. THE VEHICLE WENT THRU A STOP SIGN, BOUNCED OFF THE GUARD RAIL AND CAME TO A SUDDEN STOP WITH THE ENGINE NOT RUNNING. THE IMPACT DESTROYED THE RIGHT SIDE OF THE VEHICLE AND THE STOPPING WAS SO ABRUPT THAT THE CELL PHONE (IN MY SHIRT POCKET)FLEW OUT RIPPING THE POCKET OFF THE SHIRT.

THE CAR WOULD NOT STOP BUT MY FAST-THINKING HUSBAND QUICKLY PUT THE CAR INTO NEUTRAL & THEN SHUT THE CAR OFF. WE DROVE TO OUR TOYOTA DEALER IN VINELAND, NJ, WHERE THEY PERFORMED DIAGNOSTIC TESTS BUT COULDN'T FIND ANYTHING WRONG. THEIR DETERMINATION WAS THAT IT MUST HAVE BEEN THE FLOOR MAT PRESSING ON THE ACCELERATOR. I AM SURE THAT THE MAT WAS NOT THE PROBLEM AND THAT TOYOTA IS ATTEMPTING TO COVER UP A PROBLEM WITH A CAR THAT IS NOT ALREADY ON THEIR RECALL LIST.

I PUSHED GAS PEDAL AND DROVE IN LOW GEAR TO NEAREST PULL-OFF. DISCOVERED LEFT FRONT BRAKE WAS SMOKING. AFTER THINGS COOLED OFF I DROVE CAR IN LOW GEAR ABOUT 6 MILES TO LOCAL SERVICE STATION. MECHANIC FOUND ALL BRAKES LOCKED AND REMOVED ALL WHEELS. HE INSPECTED ALL ROTORS, CALIPERS BRAKE LINES, ETC AND FOUND NO PROBLEMS. (I HAD NEW BRAKES INSTALLED AT DEALERSHIP ABOUT 4 MONTHS EARLIER.) WHEN MECHANIC MANIPULATED LEFT FRONT CALIPER ALL BRAKES DISENGAGED. MECHANIC FOUND BRAKE FLUID LEVEL WAS NORMAL. I'VE DRIVEN CAR ABOUT 500 MILES SINCE PROBLEM OCCURRED WITH NO PROBLEMS. I DON'T USE CRUISE CONTROL OFTEN - AND HAVEN'T USED IT SINCE PROBLEM OCCURRED. I'M WONDERING IF PROBLEM IS WITH CRUISE CONTROL RATHER THAN BRAKES??

EVENTUALLY, IT EITHER IT LET UP ON ITS OWN, OR I SHIFTED INTO NEUTRAL AND SLOWED, I AM NOT SURE WHICH -- IT HAPPENED SO FAST. I IMMEDIATELY GOT OUT OF MY CAR AND LOOKED TO SEE IF ANYTHING WAS ON THE ACCELERATOR, BUT THERE WAS NOTHING. I DO HAVE FLOOR MATS, BUT THEY ARE CUT TO AVOID THE PEDALS AND IN FACT WERE NOT CAUGHT ON THE PEDALS. THIS IS THE ONE AND ONLY TIME IT HAS HAPPENED.
