Problems with 2004 Toyota Sienna STEERING

While my vehicle is in motion on city streets and highways at speeds between 35 and 55 mph, on a straightaway and curve, the stability control light/and alarm comes on randomly. sometimes it's just the alarm that sounds, and sometimes the alarm sounds and the brakes activate and the minivan swerves. was the most frightening and dangerous experience ever with my young grandchildren riding with me. i actually had to pull over to the side of the road to calm myself. this has now happened on several occasions with today (7-24-19) being the latest experience.

Steering problem sometime it's hard to steer it's dragging it's too dangerous.i almost got an accident because the steering didn't react when i'm changing lanes

When on a curve the traction control engages affecting the brakes and steering of the vehicle. speed does not seem to matter, it has engaged at 10mph and at 65 mph. last straw was when it engaged on the straight away on the highway at 65mph in the high speed lane dropping the speed down to 35mph almost causing a serious accident. it's been happening for a couple of months and two independent mechanics were not able to figure out the problem even after running a moving vehicle diagnostic. it went off a total of 18 times in a aproximate 15 minute, three mile drive with the mechanic. after watching many videos, and complaints online, why hasn't something been done on this issue that has been going on for over eight years now? i'm afraid to take this vehicle on the highway anymore!!!

Traction control malfunction. while driving on curvy roads there is a beeping alarm, steering locks up, brakes engage. the car seems to think that the traction is off. this has been a problem for over a year. no problems driving in city. only happens on curvy roads.

The vsc is going off randomly, in dry, safe conditions. almost always when i am turning to the left in a long turn. but has also happened on a windy road, driving 15mph or less, on ever single turn sometimes just the alarm, light flashing on dash & engine dethrottling, other times add the steering wheel pulling & brakes pumping themselves. we have had it in 3 different shops & the computer detects no codes, all parts in question (suspension, yaw, rotational position sensor, etc) are in good working order, nothing loose, worn or otherwise not functioning properly. we have had the yaw sensor replaced after reading many other reports of this issue, but it didn't help. we love our van, but it is now a death box. we never know when the vsc malfunction will activate, making the car unsafe to drive. when will toyota acknowledge this & help owners?

Tl* the contact owns a 2004 toyota sienna. while driving approximately 50 mph, the traction control warning indicator illuminated and a warning chime sounded. the vehicle lost steering and braking ability, and the steering wheel started to jerk from left to right. the contact continued to drive and the failures went away after thirty seconds. the contact stated that the failures randomly started approximately one year ago and grew worse. the contact also mentioned that the lock on the sliding door showed that it was unlocked; however, no one could exit the vehicle when attempting to open the door from the inside or the outside. the vehicle was not taken to a dealer or an independent mechanic for diagnostic testing. the manufacturer was notified of the failures. the vehicle was not repaired. the approximate failure mileage was 150,000.

When traveling at highway speeds and usually on a slight curve to the right, the traction control alarm and breaks go off causing the van to jerk and shake. we have been told this might be low tire pressure but the tires are fine. we have had an alignment, new tires this problem happens randomly and we have not been able to reproduce it for the mechanic. we have been dealing with this for a couple of years maybe happening 20 times. i feel it is just not safe enough to drive or pass this problem on to someone else. i wouldn't want the car on the road with me either i have read online of other toyota sienna's with the same exact problem. this is not isolated and is a safety concern.

Steering do not stay straight while i am driving this vehicle. since i purchased, i went to toyota in the beginning they fix it but issue was not resolve and as of today same problem and i replaced new tires still alignment is the biggest problem. lighting is not strong to see deer on the road.

For no reason the vsc and traction alarm goes off the vehicle brakes on its own dangerously. it is happening daily. usually when going high speed and around a left bend. i went and had the system reset as is called for after alignment. that didn't fix it. i had the steering angle sensor replaced and that didn't fix it. the yaw replaced and that didn't fix it. so now what? this is dangerous for my family.

When i drive my van the vsc and trac off lights come on intermittently and cause the vehicle to bog down and pull towards oncoming traffic. i took my van to the dealership and they suggested replacing the steering sensor. we replaced the sensor and the problem persists. with no codes coming up they say they can't fix my van. it happens while driving around corners at 35 mph mostly but has also happened a few times on the freeway at 70. all times it has happened so far has been on dry pavement. toyota doesn't seem to think that there is really a problem since no codes are coming up on their code reader. due to the frequency of the issue i am having it could be disastrous and end up in a head-on collision. how come this vehicle hasn't been recalled. i have included a photo of my service report from the dealership. also there are multiple complaints in different forums regarding this same issue and as far as i have read there is really no resolving it.

While driving the vsc comes on randomly. causing the vehicle to try to pull into oncoming traffic. it happens quite a bit and is potentially deadly.

While driving at 55 mph or faster, generally on a right hand bend, the vsc will activate pulsing the brake and violently pulling the car to the left and towards oncoming traffic. the skid light goes on, and the car beeps until you are out of the turn and then it goes away. this problem has been intermittent for about 6 months but has gotten much worse and more frequent in the previous 2 months. it has been to the dealership several times and they do not know what to do. there are no error codes. the best they can say is "you're going to fast..." which is a wholly unacceptable answer considering we are going the speed of traffic and no more than 0-10 over the speed limit. *tr

The vsc traction control system activates on it's own. driving the van it automatically comes on and brakes the van, dashboard light and beeping noise comes on. brakes you automatically causing the van to veer to the right. this malfunctioning devise with the yaw system is continuing after many trips to the local toyota dealer. they currently have the van and are replacing part after part and the problem still persists. contacted toyota headquarters and filed a complaint with them but they say there is no recall on this van. checked on line and found many other toyota sienna owners who are experiencing the same issues as we are. this is a dangerous safety hazard which can cause an accident. as of today's writing the problem has not been diagnosed by toyota.

Unexpected vehicle stability control activation while driving resulting in automatic braking and unexpected steering pull. i have been experiencing this issue over the past 4-5 years. there have been times where this issue has led to almost striking vehicles around me. i have brought the vehicle to a toyota dealership, but they have not been able to fix the issue. on several online bulletin boards, other owners of toyota sienna have complained regarding the same issue. i just read in the news that similar issues are occurring on 2001-2002 toyota sequoia.

On numerous occasions, we have had the vsc indicator light turn on while driving on dry pavement while on the highway, which caused the car to apply the brakes and also swerve. our car is awd so the first time it happened, we thought there must have been black ice on the road (even though the road appeared dry). it first happened about three years ago, although it is happening more frequently now. we drove home yesterday through the mountains and it happened four times on our two hour drive. it mostly happens while going downhill for us, and has happened at speeds of 70 mph - 30 mph. it has happened while turning (both directions) and going straight. it is very scary for both my wife and i, and i feel unsafe with her driving our car with our four children. we've taken it to the dealership and they want to charge us lots of money to try to fix what they "think" the problem is. i have spoken with other sienna owners who have experienced the same frightening experience so know it is not just our car, driving, etc.
