Car engenders self braking and cutting power off
While driving on a slope, incline or decline, my traction control light ( car with squiggles behind it) comes on, a loud 'beep beep beep' sounds, and my car brakes on its own. always happens while in motion. highway driving. 90 percent of the time while on an incline or decline. it scares the heck out of you causing an unsafe condition. additionally, when the brakes apply, it pulls you out of your lane. the first occurrence was 3 weeks ago. has happened multiple times since. it doesn't seem to be intermittent anymore. you can count on it happening when your on a slope.
The traction control erroneously engages under normal driving conditions, which in turn activates the abs. this causes sudden and unexpected braking. this is dangerous and could lead to loss of control of the vehicle.
The stability control/traction will activate for no reason thus slowing the vehicle down at freeways speeds. mechanics find no problems with parts associated with issue.
When turning corners, the vsc light turns on, the car beeps, and the abs system engages, causing the car to brake on own. this happens every day, intermittently, at all speeds.
The traction control system comes on when going into any right turn. the alarm beeps and the car automatically brakes, and the gas pedal is disabled so that you can not speed up. the braking can be so severe that it will reduce speed from 45 mph to 25 mph without notice which jerks the passengers violently.
While driving the vehicle at higher speeds (greater than 40 mph) around curves, the skid indicator sensor will occasionally trigger even on dry pavement where no slipping is happening. the car will automatically decelerate and brake momentarily. there is often a clicking sound in the steering column as well. the vsc warning light occasionally comes on too. mechanics on multiple occasions have not been able to figure out what is causing the problem. however, based on research at toyota blogs, it appears that other toyota sienna drivers have experienced this same issue.
The vsc and traction control system and slip indicator warning lights come on around curves just as the front wheels grab. i have taken it to several mechanic s and toyota dealership and they said nothing shows up on the dynastic test machine. so, it seems to me that this is hazardous situation and records show i hold toyota responsible for my family's safety and well-being.

We have a 2008 toyota sienna. the vehicle has 174,000 miles on it. the vsc icon comes on along with the alarm when driving on dry roads and when turning whether on flat or downhill travel with the brakes grabbing and releasing. the situation is unpredictable. problem started at approximately 173,000. the slip indicator light started coming on intermittently while turning on highways etc. please make this serious recall for toyota. you need to force toyota to take this seriously before someone loses a life.

Vehicle traction control intermittently engages on drive pavement in curves and straightaways at varying speeds. vehicle alarm beeps, vehicle brakes, and vehicle automatically steers. this is a dangerous, unsafe situation especially at higher speeds for the affected vehicle and trailing vehicles. this has occurred without predictability many times.
Tl* the contact owns a 2008 toyota sienna. when the contact switched lanes or made a turn, the brakes activated on their own. the failure occurred on flat or curved roads and while driving 30 mph. sometimes the brakes worked properly, but sometimes they did not work at all. the contact also stated that the vehicle would occasionally accelerate and decelerate on its own and the steering wheel made an abnormal ticking noise. furthermore, the vsc and traction control indicators illuminated. the vehicle was taken to toyota knoxville (10415 parkside dr, knoxville, tn 37922), but they did not assist. the vehicle was then taken to fox toyota (228 fox family ln, clinton, tn 37716) where it was diagnosed that a steering angle sensor needed to be installed. the vehicle was not repaired. the manufacturer was made aware of the failures and provided a case number. the failure mileage was 170,000. *bf *tr
Tl* the contact owns a 2008 toyota sienna. while driving above 55 mph on an inclining or descending surface, the stability control would suddenly activate and the speed would suddenly decrease. there was no response when the accelerator pedal was depressed. the contact indicated that the failure also frequently occurred when switching lanes. the vehicle was taken to an independent mechanic who was unable to determine the cause of the failures. the manufacturer and local dealer were not notified. the failure mileage was 130,000.
October 2016 this problem of my 2008 toyota sienna started- on slight curves doing 30-40mph i would hear a clicking noise coming somewhere underneath the front right end almost as if under the dash, the vsc light would flash. i took to a toyota dealership, had a mechanic test drive with me they said the problem was that my tires werent aligned with my last tire change(which was done at their toyota dealership) toyota told me i needed to replace all the tires and have the wheels aligned. i did this, problem continued. i took my van in again to toyota, they lied and told me i needed new brakes, and some other things i didnt need. decided to get a 2nd opinion from 2 other auto shops and found out toyota lied about the brakes, they were fine and they both were unable to find out my problem. i found this out going to 2 other auto shops asking for them to look into the original problem. now today may 2019 this problem still exists, but has gotten worse. now-the vsc light comes on, it still clicks, the abs light and warning sound goes off, feels as if ...
While driving the vsc/abs system comes on unexpectedly causing vehicle to brake and effect steering. it is most frequently noticed when steering on curves 30-40 mph. i have replaced tires, front steering components and dealer cannot duplicate. i believe wheel speed/yaw sensor calibration is affecting the vsc system. this is a very scary situation to be in that could lead to a serious accident. your braking and steering affected all at once unexpectedly is dangerous. please investigate and provide solution asap.
While passenger side visor is down smoke starts pouring out from under the head liner. when the visor is placed back in the closed position smoke clears out and stops. per the mechanic, a short in the electrical system has resulted in a melted electrical board and the entire head liner and electrical board needs to be replaced. the visor can not be used or the short may start a fire inside the vehicle. the vehicle was in motion when this occurred. van filled with smoke quickly. had to pull over and open doors to clear the smoke.
