2008 Toyota Sienna steering problems

“I have had the traction control go on while driving on the highway even when I turn it off. Sometimes the VSC and TRAC OFF lights go on while driving. The roads are dry. Whenever I take it in to the mechanic, all the lights are off. They pulled a zero calibration code and recalibrated. It still kept happening. Then I was driving around a curve on highway speeds when the traction control light went on and the van suddenly braked on its own and I almost lost control. The tires are new and the roads were dry.”

“Issues with VSC. The sensor alarm goes off when driving at more than 50 mph and slightly turning the steering wheel. The car brakes itself and this is DANGEROUS. It happens all the time, it has been more than 5-6 years and we are to the point of not using the car on the freeway to prevent a potential fatal accident. I found posts describing the same issue with this model of Toyota. Car should be recalled to get this fixed.”

“The Vehicle VSC Engaged multiple times even at low speed of 30 mph under the road speed limit. The brake applied and even the vehicle stop to respond to the acceleration. We have 3 little kids and old parents in this vehicle.Toyota should own this problem and fix it free of charge as a factory recall.”

“2008 Toyota Sienna. Driving down steep right turns, VSC light comes on, urgent beeping alarm and tires grip and grip vehicle brakes going 20-30+ mph on dry road. Very scary and dangerous, and has continues repeatedly over the past year on curvy right turns. Local mechanics don't know what is wrong with the vehicle. Many Sienna owners have similar problems listed on Carguru. https://www.cargurus.com/Cars/Discussion-c9152_ds656326 Please insist on a manufacturing recall for this vehicle. It is unsafe and could easily cause an accident. Thank you. Concerned original car owner.”

“WHILE ON AN ON-RAMP; THE VEHICLE AT ABOUT 35 MPH STARTED BLINKING THE SLIP LIGHT AND SLOWED THE VAN DOWN, ALSO CAUSING I THINK THE BRAKES TO ENGAGE WITH FORCE. HAPPENS WHILE DRIVING NORMALLY AND ON RAMPS. I HAD THE RACK AND PINION REPLACED AND STILL HAS DONE THIS.”

“THE VEHICLE STABILITY CONTROL WILL UNEXPECTEDLY ENGAGE IN INSTANCES WHERE IT SHOULDN'T ACTIVATE. THE MOST COMMON IS A LONG, SLIGHT CURVE ON AT FREEWAY SPEEDS ON DRY PAVEMENT. THE SECOND MOST COMMON SCENARIO IS ACCELERATING TO ENTER THE FREEWAY. WHEN VSC ENGAGES, THE VEHICLE WILL LURCH TO THE SIDE IT WAS ACTIVATED ON AND CURTAIL ANY ACCELERATION. THIS MAKES THE VEHICLE HARD TO CONTROL WHEN ON A FREEWAY CURVE AND WHEN ATTEMPTING TO ACCELERATE TO MERGE ONTO THE FREEWAY, CAUSING UNEXPECTED MOTION THAT IS A HAZARD TO REMAINING ON THE ROAD OR CAUSING THE VEHICLE TO BE IN AN ACCIDENT WITH OTHER VEHICLES. THERE IS NO INDICATION THAT THERE ARE MALFUNCTIONS IN ANY SYSTEM THAT WOULD CAUSE THIS TO OCCUR. NOTE: MILEAGE ON THE ODOMETER IS ~170,000 MILES.”
