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.
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.
I am having a massive problem with my vsc. randomly, regardless of speeds (it's happened going 70 as well as 25, and 40 mph), my vsc will kick on, kill my speed, and cause me to swerve. as you can imagine, going 70 on an interstate with other vehicles around and having this happen is life threatening not only to me and my family but other vehicles around me. reading on several auto forums, this problem has been drawn to the attention of toyota corporate to no avail. it is absolutely beyond me that they see no reason to file a recall.
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.
Traction control kicks in for no reason, tration beeping and tires lock,at freway speed traction control activates and cuts off speed dramatically.very unsafe to drive.
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.
The vsc sensor is activating during normal driving conditions without warning. this is causing the van to aggressively apply the brakes and lose acceleration. this issue mainly occurs when turning down while going down hill, however it happens randomly in other instances as well. i have been in several life threatening instances where the brakes are being applied while traveling through mountains with large semi trucks behind me.. nearly causing several accidents. my research points to a few things that could possibly be the culprit: the yaw sensor stearing wheel rotational position sensor vsc computer module this video captures exactly what is happening to my vehicle. https://www.youtube.com/watch?v=tgmjafpifko i cannot find any instances where this issue was fixed online
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.
I have experienced the issue with 2004 sienna le with 130,500 miles. traction control kicks in at 45-60 miles per hour on straightaway, clean pavement, no rain, no snow, and brakes car and cuts power. almost lost control of vehicle when it happened, steering into other lanes. it happens frequently and is very possible to have the car rear ended if a car behind me is closing on as the speed suddenly slows down. apparently this is a big issue that i found lot of other sienna owners is sharing from the forum. as far as i know that many toyota dealership is not intend to acknowledge such issue and able to fix them.
When i am driving my 2004 sienna, its shaking so badly i feel like wheels going to roll out. also brake make worse, and engine mounts and transmission mount are very bad condition. i don't know why its bad breaking in rain.
The steering angle sensor, pn# 89245-08011 failed. the van can not be driven over 23 mph. the brakes come on automatically over 23 mph and the engine will not respond to accelerate. the steering seems strange (anti-lock brake light coming on) but i was able to keep the van in my lane of traffic. i am concerned that this sensor or others will fail and the van will automatically apply the breaks and loose power preventing me from maneuvering the van to the side of the road. i do not know what would have happened if i was travelling at highway speed. i consider this a major safety problem.
