The Traction Control System commonly malfunctions while making turns on curving road sections. I will lose power through turns as the TCS light blinks on my dashboard and makes a beeping sound. On some occasions the brakes will automatically engage in the tire that the car perceives as experiencing slippage. This problem is continuously worsening and commonly endangers me and my passengers, as the car engages brakes or cuts power to the engine at unexpected and in opportune times.

I have fixed my alignment ,new tires, all of the front suspension and nothing prevents the car from trying to brake for me. it is a safety feature that is not safe at all. a car slamming on your brakes at any speed is dangerous in addition to that it seems to cut off your fuel , leaving you unable to accelerate until its done beeping which can take a long time. the vsc , chenk engine and trac off flash there is no crash to report I have been lucky so far

While driving typically around 35 mph and either left or right turn the vehicle traction control engages and the van brakes and steering is affected. The roads have always been dry and in each instance the speed of the van was at or below the speed limit - traction was never lost and yet the traction control engaged as if we were in a skid. This occurred at least 12 times while driving to and from a day trip in the mountains (windy road). It has also happened multiple times at around 50 mph while turning left on a nearby flat freeway. An independent service shop has not been able to replicate the problem. The safety of the driver and passengers were at risk when it occurred on the freeway as a driver behind us got close to rear ending the van while it was in its brake mode.

- Traction control engaged at high speed(70 mph on interstate) causing the vehicle to brake abruptly and pull the vehicle to the right. Had I been traveling in the left hand lane, I could have been forced into the right hand lane causing a collusion with another vehicle. Also occurred at lower speed(30 mph on a windy road) causing the same issue as described above, almost causing the vehicle to leave the paved surface. - Mechanic was able to duplicate the issue - Mechanic diagnosed intermittent traction control activation, scanned computer for codes. Yaw rate/steering angle correlation causing false activation ABS/traction. Replaced hub bearing and spindle. Four wheel alignment, including check castor, camber and adjust toe. Performed zero point calibration and reset ABS memory. - Traction control lights up briefly

About a year ago the Vehicle Stability Control warning light along with an audible alarm started coming on intermittently while turning on highways going uphill or downhill in dry weather and with no risk of any tire slipping. At first this only happened at higher speeds 65+mph. Over time, it has occurred more and more frequently and can occur at speeds down to 25 mph. At times, the Anti-lock Braking System is also activated resulting in jerky braking and loss of throttle. When people have been following me too closely, this has almost caused accidents. When these symptoms occur, it is always on a curve (of any degree, even slight curves) and while driving at least 25 mph, and even happens on flat turns now. The weather has always been dry with no risk of tire slippage.

Sometimes when I take turns in my Sienna, the VSC starts going off and braking individual wheels without my control. This happens unexpectedly on highway bends at speeds of 60+ mph and it is difficult to control the car and keep from swerving into another lane. If the roads were icy when this happens, it would probably cause a dangerous accident. Toyota has a technical service bulletin for this, but not a recall - which it should since this is a significant safety issue. The TSB is BR008-04. There are many others experiencing this same issue: https://forums.edmunds.com/discussion/13855/toyota/sienna/vsc-sudden-activation-2004-toyota-sienna

While driving on dry freeway or other stable road conditions, the Electronic Stability Control kicks in, braked hard, causing the van to swerve, and the lights on the dash started flashing, accompanied by a loud beeping. This has happened multiple times now. There is no reason for this to be occurring. It is involuntary, sudden, and random. If someone were close behind me, they could rear-end the vehicle. It also sometimes pulls the steering so hard that it swerves into the other lane. This is a serious safety issue that Toyota needs to deal with.

Official recalls
10May 22, 2014
Toyota Motor Engineering & Manufacturing (Toyota) is recalling certain model year 2004-2011 Sienna vehicles originally sold in, or currently registered in, Connecticut, Delaware, Illinois, Indiana, Kentucky, Maine, Maryland, Massachusetts, Michigan, Minnesota, New Hampshire, New Jersey, New York, Ohio, Pennsylvania, Rhode Island, Vermont, Virginia, West Virginia, Wisconsin and the District of Columbia. The affected vehicles have a spare tire carrier assembly mounted under the vehicle whose attachment cable may corrode due to high concentrations of road salt splashing onto the spare tire carrier.
Consequence & remedy
Consequence: If the carrier cable is corroded due to road salt, the spare tire may separate from the vehicle, increasing the risk of a crash.
Remedy: Toyota sent owners in August 2014 an interim notification to advise owners of the recall and that dealers will perform an interim remedy to remove the spare tire and relocate it to the luggage compartment, free of charge. Owners are being mailed a second letter as parts become available and dealers will replace the spare tire carrier assembly with an improved one, free of charge. The remedy campaign is being performed in phases. The first phase of the recall began July 7, 2015. Owners may contact Toyota customer service at 1-800-331-4331. NOTE: 2004-2010 Siennas subject to this recall were subject to recall campaign 10V-160 initiated in 2010. Those owners are advised that they must have their vehicles remedied again under this campaign and that having the earlier recall completed did not remedy their vehicles. Additionally, model year 1998-2003 Siennas were recalled as part of safety recall 10V-160. Owners of those vehicles that have not had not the remedy performed on their vehicles, should contact their Toyota dealer to schedule a free repair.
Sep 26, 2013
Toyota is recalling certain model year 2004-2005 Sienna vehicles manufactured January 10, 2003, through August 10, 2005; and model year 2007-2009 Sienna vehicles manufactured February 20, 2007, through December 12, 2008. In the affected vehicles, due to a problem within the shift lock solenoid, there is a possibility that the shift lever could be moved out of Park position without depressing the brake pedal.
Consequence & remedy
Consequence: If the shift lever is moved out of the Park position without the brake applied, the transmission will either engage a drive gear or Neutral, increasing the risk of a backover or roll away crash.
Remedy: Toyota will mail interim notifications to owners beginning in late October 2013. When parts are available, owners will be sent a second notice and dealers will replace the shift lock solenoid, free of charge. Owners may contact Toyota at 1-800-331-4331.

THE OFFICE OF DEFECTS INVESTIGATION (ODI) OPENED A PRELIMINARY EVALUATION, PE08-041, TO INVESTIGATE ALLEGATIONS OF STEERING BINDING OR INCREASED STEERING EFFORT CAUSED BY CORROSION OF STEERING INTERMEDIATE UNIVERSAL JOINTS IN MODEL YEAR (MY) 2004 TOYOTA SIENNA VEHICLES.TOYOTA'S RESPONSE TO ODI'S REQUEST FOR INFORMATION IN PE08-041 INDICATED THAT TOYOTA HAS BEEN INVESTIGATING REPORTS OF INCREASED STEERING EFFORT IN MY 2004 THROUGH 2006 SIENNA VEHICLES SINCE 2005. TOYOTA DETERMINED THAT A COMBINATION OF THERMAL DAMAGE AND SUBSEQUENT WATER INTRUSION COULD LEAD TO CORROSION OF THE LOWERMOST UNIVERSAL JOINT INSTALLED ON THE STEERING INTERMEDIATE SHAFT OF THE SUBJECT VEHICLES.

(2) THERE IS A LARGE VARIABILITY IN THE PRESSURE AND DRIVING TIME ATWHICH THE TPWS WILL TRIGGER THE TPWS WARNING LIGHT TOILLUMINATE. (3) THE TPWS MAY NOT MAKE AN ACCURATE JUDGMENT UNDER A VARIETY OFROAD OR DRIVING CONDITIONS, INCLUDING IF THE VEHICLE IS DRIVENOVER 62 MPH, THE OUTSIDE TEMPERATURE IS BELOW 32 DEGREESFAHRENHEIT, THE TREAD WEAR IS UNEVEN, THE LOADING IS OVERTHE LIMIT, OR THE PRESSURE OF 2 OR MORE TIRES DROPS AT THE SAMETIME. (SEE TOYOTA'S APRIL 10, 2006 INFORMATION REQUEST RESPONSEFOR MORE DETAILS.) (4) SOME CONSUMERS REPORTED THAT THEIR TIRE PRESSURE WAS BELOW 15PSI OR EVEN AS LOW AS 0 PSI BEFORE THEY REALIZED THAT THEY HAD ATIRE PRESSURE ISSUE AND AS A RESULT HAD TO REPLACE THE TIRE. NOTE: TOYOTA STATES THAT IF THE TIRE PRESSURE DROPS TO BELOW 15PSI, THE TIRE CAN NOT BE REPAIRED. (5) IN APRIL 2006, IN RESPONSE TO REPORTS OF PREMATURE OR UNEVEN TIREWEAR, TOYOTA ISSUED A CUSTOMER SUPPORT PROGRAM TO PROVIDESUPPLEMENTAL TIRE WARRANTY COVERAGE FOR 2004-EARLY 2006 MYSIENNA VEHICLES WITH RFTS. (6) FIELD DATA AND NHTSA TESTING SHOWED THAT THE TPWS ON THE 2004-2005 MY TOYOTA SIENNA 2WD VEHICLES, WHICH USE THE SAME TPWS AS THE SUBJECT VEHICLES, BUT HAVE STANDARD TIRES, PERFORMED BETTERTHAN TPWS ON THE SUBJECT VEHICLES.DUE TO THE FOLLOWING REASONS, ODI HAS DECIDED THAT FURTHER EXPENDITURE OF AGENCY RESOURCES ON THIS INVESTIGATION IS NOT WARRANTED AT THIS TIME: (1) ONLY A VERY SMALL PERCENTAGE OF TPWS AND TIRE RELATED COMPLAINTS AND WARRANTY CLAIMS CITED THAT THE TPWS DID NOT ILLUMINATE ON THE SUBJECT VEHICLE DURING THE INCIDENT.IN THE REMAINING TIRE RELATED INCIDENTS, IT WAS NOT POSSIBLE TO DETERMINE IF THE TPWS CONTRIBUTED TO THE TIRE RELATED FAILURE. (2) ODI IS NOT AWARE OF ANY INCIDENTS THAT WERE REPORTED THATRESULTED IN THE DRIVER LOSING VEHICLE CONTROL. (3) THE FIELD DATA DID NOT ESTABLISH A RELATIONSHIP BETWEEN POORTPWS PERFORMANCE AND TIRE INCIDENTS WITH SAFETY CONSEQUENCESACCORDINGLY, THIS INVESTIGATION IS CLOSED.THE CLOSING OF THIS INVESTIGATION DOES NOT CONSTITUTE A FINDING BY NHTSA THAT A SAFETY-RELATED DEFECT DOES NOT EXIST.THE AGENCY WILL CONTINUE TO MONITOR COMPLAINTS AND OTHER INFORMATION RELATING TO THE ALLEGED DEFECT IN THE SUBJECT VEHICLES AND TAKE FURTHER ACTION IN THE FUTURE IF WARRANTED.
