Problems with 2005 Toyota Sienna ELECTRONIC STABILITY CONTROL

When driving at any speed above 25 mph, the traction control light on the dashboard will come on, it will beep and the brake will engage without the driver pressing the brake pedal (these all happen at the same time). this in turn locks the brakes at times and the car veers to the right. there is no reason that we can figure out that this happens. it has happened many times and three days ago, it happened twice in one day. we have taken our vehicle to hendrick toyota in wilmington nc and provided them a video where two owners took videos each time it happened in their vehicle. i also provided them with email discussions from two different web sites where owners were discussing the issue. we believe this should be a recall for toyotas.

I have a 2005 toyota sienna where the vsc system activated randomly and slowed our van down. when it first happened we thought that the van broke down because there was a beeping sound and it seemed like the brakes activated by itself. kinda scared us because we were going around a turn at 60mph

Tl* the contact owns a 2005 toyota sienna. while driving approximately 20 mph, the vehicle started to lose power for a few seconds and the esc warning indicator flashed. the contact stated that the failure occurred every day when exiting the highway for approximately six months. the vehicle was taken to team toyota of princeton (2871 us-1, lawrenceville, nj, 08648) to be diagnosed, but they could not replicate the failure. the manufacturer was not notified of the failure. the vehicle was not repaired. the approximate failure mileage was 161,388.

Vsc system activates the abs while driving under normal conditions. usually on interstate entrance/exit ramps, the vsc light comes on with loud beeping noise and activates the anti-lock brakes. the vehicle pulls either to the left or right and acceleration is affected. it's very scary! speed limit on ramp is 55mph and it happens when going 45-50mph. it's also happened while driving 35 mph. it happens at multiple locations. i've had the car checked by 3 different shops and nobody can figure out what's going on. it's a weekly occurrence.

Vsc keeps engaging / with lights and alarms, the car looses power and pulls to right. this occurs unnecessarily at different speeds below 20 mph and at 65 mph on a freeway straight away and on & off ramps of the freeway. this is happening with dry / good weather operation. i have owned this vehicle for 1 week and have had this happen at least a dozen time.

Airbag light for driver side blinks off and on during driving at speeds between 35-45 mph. this occurred at 209,560 +/- miles. this is occuring with other issues in the electrical modules including abs control malfunction, power supply voltage yaw/deceleration sensor and it loses communication with steering angle sensor module. this seems to not only be an issue with my vehicle but others as well from reading many forums on toyota sienna vans including ones just a few years old.

Check engine light, vsc and trac off. as i was driving after just purchasing this vehicle from a dealer after about 60 miles or so these lights all came on the same time. i was told after a scanner was placed on the vehicles computer system that it is due to either catalytic convertor/o2 sensor malfunctions.this is an important exhaust and emission component designed to burn up toxic exhaust fumes that sets off these lights. this is a major issue with not only this vehicle but other toyotas. this needs to be addressed. we in the usa would like to breath clean air and it doesn't seem feasible to have to continue to "fix" these sensors designed to make consumers spend large amounts of money to fix their vehicles.

While driving approximately 10 - 15 mph under the speed limit on a gently curving overpass, the stability control engaged, sharply jerking the steering uncontrollably in the wrong direction and hindering my ability to steer the vehicle or brake. this has happened twice previously, both on curves, and on neither of those occasions was i exceeding the speed limit, nor was there any reason for the system to engage.

Tl* the contact owns a 2005 toyota sienna. while driving approximately 30 mph, the stability control warning indicator illuminated. the vehicle decelerated and the rear end swerved sideways. the contact stated that the failure occurred for approximately 30 days and only when driving above 30 mph. the vehicle was not taken to the dealer or an independent mechanic for diagnostic testing or repairs. the manufacturer was notified of the failure. the approximate failure mileage was 143,000.

Two instances in oct 2017 of brakes activating without driver action. braking accompanied by beeping - possibly electronic stability control (esc) activation signal. braking reduced speed approximately 10-15mph. both instances occurred on the same road, a curvy 45mph limit asphalt 2-lane. conditions dry, ~50 deg f. braking occurred on a straight section and did not pull the car to one side. do not believe anti-lock engaged. van has 137k miles.toyota service (11/9/17) : "no problems found no codes stored no vehicle event log (vehicle does not have that capability) more obvious and likely cause could have been the fact that the front tires were at 20 psi and the rear at 35 psi, the disparity in wheel speed signals could have triggered a false event." verbal report confirmed "no problems found" including steering rack bushings, steering angle sensor, and wheel speed sensors. the service representative, with 6 years experience as a mechanic, said he had encountered this problem before but it was rare. he also stated that an apparent difference of only 1mph in wheel speed could be enough to cause inadvertent esc activation. however, he was unsure why the problem, if it was caused by ...

While on the road, infrequently as we start hitting continuous curves, the beeping starts with slip control symbol coming on. the brakes engage on their own. it doesn't seem to matter how fast or slow we take the curves. i have no control over the vehicle at that point and it starts braking itself for few seconds. very dangerous on the curves and especially if someone is behind you.

Takata inflators - when driving in city 30mph or freeway 50-60mph in curvy path, the unti-skid lock turns off even if the road was dry. when it happened frequently and a motorcycle almost slammed from behind, i brought my van to the dealer and it shows no record of the unti-skid lock being on. i insisted to take precautions and they did a zero calibration, changed new tires and realignment but problem persist. i brought it back with the same complaint but they claimed the they never had any other customer with the same problem. i reached online yet there were many others. i hope you can help me on this. the dealer can't figure out this problem and just washed their hands. this happened multiple times already and afraid to drive my van.

While driving on a normal day no rain or any slippery condition on the road going about 40 miles an hour my vehicle anti slip system ingaged and break momentary and vehicle slowed down this happens several time why is this system engaging when it's not raining or no slippery condition existing on the road.

Sienna was accelerating from 40-45 mph and a slight right turn on a city street, when the vsc lights turned on and applied brakes. city street was dry, weather was clear and sunny.

This report includes two separate safety issues. first issue: after backing out of my driveway onto my street, my car would not shift into drive gear from reverse. the engine would not restart after turning the key off since it was still in reverse, even though the lever was shifted back to park. thankfully, i don't live on a busy street and there happened to be a few linemen doing work that were able to push the van back into my driveway. with two young children in the car and not being able to push the van on my own, this could've been a very dangerous situation in a busy location. after disassembling the dash, my husband discovered the mechanism in the gear shift had malfunctioned and was able to repair it himself instead of towing it to a toyota dealer for pricey repairs and towing fees. second issue: on multiple occasions (usually, but not always, while accelerating onto a highway on-ramp) the traction control light will illuminate, a repetitive beeping will sound, and the steering wheel vibrates and becomes difficult to control since it freezes up. this has happened on dry roads and ...
