Brake Sensor Problems of Toyota Sequoia - part 1

When driving at 70mph or higher a light comes on at the dash board vsc trac off the car loses speed and veers right to left almost loosing control of the steering wheel a diagnostic gave me a code c1234 wich is related with the stability control system yaw rate sensor / computer recalibration. This sensor is supposed to last the life of the car.

Accelerating onto highway the car made grinding noise and pulled to left as well as suddenl braking. It was almost a disaster but car in next lane veered away and I pulled onto shoulder. I had been told the yaw sensor needed to be replaced but was not available anywhere. When I looked online I saw NHTSA did not feel it was a dangerous failure, but it read as more of an inconvenient problem so I was comfortable trusting them and drove it after the dealer had said it couldn't get the part. Why was Toyota able to declare a part obsolete that obviously is important to my safely operating the vehicle? how can. The NHTSA possibly think this is not a safety issue?.

Tl the contact owns a 2001 Toyota Sequoia. While driving approximately 40 mph, the variable speed control malfunctioned. The contact stated that the abs and traction control indicators illuminated without warning. The contact depressed the brake pedal, while turning, and a hard vibration occurred. The contact stated that the vehicle returned to normal immediately afterwards. The contact parked the vehicle and contacted coos bay Toyota (2001 n bayshore drive, coos bay, oregon 97420, (541) 267-3121) where it was diagnosed that the yaw rate sensor was faulty and needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure. The VIN was unavailable. The failure mileage was approximately 190,000.

The master pressure sensor is failing and from what I am reading this has been a common complaint in the early 2000's Toyotas but no one has done nothing about it besides charge an awful amount to fix. My vehicle when in 4wd brakes will lock up and I still slide no matter what gear or how slow I am going. I have almost slid into countless cars.

When driving on normal (safe and dry) road conditions, the vsa and trac control elements of the vehicle engaged and nearly caused me to crash. Braking was severely inhibited (had to pump brakes to get them to work) and steering was jolted to the right/affected nearly causing an inadvertent lane change at highway speeds (65 miles per hour). Was assessed by Toyota and ruled to be a faulty steering column sensor and yaw rate sensor which is an astronomically expensive repair. My family is not safe in this vehicle due to the defect. Please do something! this should be a recall!.

2002 Sequoia sr5 milage 150322. Been reading complaints on traction control that trac off and vac trac lights turn on and inside cab starts beeping and grinding noise comes from driver side wheel and looses rpm's. Thats what happening to my truck also. Used code scanner at its saying its the yaw sensor why haven't this issue been recalled. Needs to be recalled. It's dangerous!!! was driving 35 mph and the street light turned red. I pressed the break and truck syarted to beep,shake,and grind, started pumping breaks truck wouldn't stop and when it did was to late had already passed the red light. I've could of caused an accident and sevierly been injured or could of injured somebody else. Lucky my family wasn't in the truck at the time it happened.

My complaint stems from the vehicle stability control (vsc) issue that commonly plagues the 2001-2001 Toyota Sequoia. As many others have filed complaints over this vsc issue, mine is no different. My Sequoia, a 4x4 sr5 with 160k miles, works flawlessly other than the vsc lights being constantly illuminated while driving. The results of the malfunction, possibly from the yaw rate sensor, present a momentarily loss of power and random unexplained steering events. The only way to temporary clear the vsc lights and the effects of the malfunction is to completely stop the vehicle, turn off the ignition and restart the vehicle. I fear a loss of control of the vehicle while my wife and kids are driving at highway speeds. I would like to see Toyota issue a formal recall or pay for a new yaw rate sensor and the consumer pays the labor. Other than the vsc issue, the Sequoia is a great vehicle overall.

When driving 70 mph on the interstate, the vehicle periodically yanks hard to the right, it sounds like I have a flat tire, front right tire feels and sounds like it stopped turning. Car slows, vsc system idiot lights flash and beep. After I have successfully though unintentionally run another car off the road it returns to normal. The idiot lights stay on until the car is turned off. Has been taken to mechanics numerous times in last few weeks, cannot find a problem. But keeps happening. Mechanic is aware of 2003 and newer recall for the same reason, tried recalibrating yaw sensor successfully. 3 days later it happened again mechanics says the sensor may be periodically malfunctioning, over correcting for a nonexistent problem. It has happened going 30 mph once, as well as today the lights and beeping went off at a dead stop in my driveway. Went straight to mechanics, turned off car to go inside, nothing found when he pulled it in.

I am the original owner of this vehicle, it currently has 155,600 miles on it. I have been very happy with Toyota and this vehicle until my recent incidents involving inability to stop while at slow speeds, followed by a loud noise and shaking and three lights illuminate when this occurs: brake, vsc, and trac control. After reading the many reports, I realize that this is quite common and am upset that Toyota has done nothing about it! I had my car towed to the dealer after the first incident as it was so frightening that I would not drive it. The sensors were no longer on and Toyota told me there was nothing wrong (my front brakes and rotors were replaced by them a few months prior). It happened again a few weeks later, this time I turned the car off and back on and got the lights to go off, then I drove it directly to my mechanic. He found three error codes associated with the abs system. He said it's expensive to replace so he reset the system and we decided to see if that works. Now, a week or so after the reset, it happened to me again in traffic. After reading all of the other very similar reports, I no longer feel safe to drive my car! please make Toyota be responsible for their negligence to their customer's safety! I found reports on this dating back to 2004 and I know there was a recall done on the 2003 models.

2007 Sequoia vsc trac sensor lights turning on and off and hearing grinding noise when accelerating and decelerating. Along with the vsc trac sensor lights turning on, the brake indicator light turns on as well. The most recent occurrence happened as I was picking up my daughter from school, and as I was pulling away from the school doing no more than 20 mph - my vehicle made a grinding noise and all the above listed indicator lights came on. I was able to (nervously) drive my vehicle home. This has also happened multiple times before at different speeds. During these instances, I have noticed decrease acceleration and my vehicle feels like the rear is sliding from side to side. I am afraid of not being able to stop in time, the brakes failing completely or a total loss of power as a result of this.

The first time my abs/vcs trac lights came on was after I had to brake hard on a downward hill. I accelerated to climb the other side of the hill and it was after doing that which the vcs trac and trac off lights first came on at around 168,000 miles. There was a fast beeping sound lasting for maybe 10 sec then it regained power. Now it will do it within just a few miles of our home. We have had several more occasions since this initial incident where there was a jerking/pulling of the right front tire. Also the air conditioning would come on and off like it was trying to surge. Also idles very low, below 500 rpm and then finally shuts off. This vehicle has become very dangerous to drive. We are not sure what to get fixed on it since we have read that other owners are being told that its anything from a yaw sensor, steering angle sensor, brake booster system, or a skid control computer issue. All of these are very pricey to get fixed and there are no guarantees that they will even correct the problem. Most have had the yaw sensor replaced and it did not correct the problem. Some of the mechanics we have talked to said that there could be brake dust or mud and road grime build up over the sensor making it malfunction and that it should be hosed off at an underbody carwash. We haven't tried this yet since we didn't put much faith in it until we discovered hearing again on youtube. The 2003 Toyota Sequoia vcs recall should be extended down to the 2002 models as well. We all are having the same issue that they did.

2002 Toyota Sequoia vsc trac sensor lights turning on and off and hearing grinding noise when it auto-engage and disengage in motion.

When slowing to a stop, my Sequoia periodically grinds when braking and the vsc sensor, abs sensor and trac sensor light turn on and stay on.

While driving along at ~40mph, car jeered to the right and made a noise as if the anti-lock brakes were pumping on the right side of the vehicle. The vsc & trac lights came on. Vehicle then drove normally until the ignition was turned off. Once the vehicle was started, the same incident occurred repeatedly making it unsafe to operate. Took vehicle to the Toyota dealership and was told I needed a new yaw sensor - $558.

Problem: brakes disengage or as I've been told the abs system is engaging when it shouldn't. The front end of my car sounds like it dropping out and I'm hearing a very loud grinding noise. This is happened several times in the past 2 years. Had brakes serviced twice in the past 2 years. Replaced pads, turned rotors. Changed brake fluid. Had sensors checked. Checked by the dealer as well as another brake shop(firestone). They couldn't find any computer codes to definitely say what the problem is. Only recommended replacing a computer part. I told them I wasn't spending over $1000 on a recommendation. Even carried it to firestone, since the dealer service dept was closed yesterday evening at 6:45pm when it happened again. Didn't turn off the car with the "brake", "vcs" and another yellow light on and they really didn't see any codes that stood out. Very frustrating and concerning with my wife and kids riding in this car!!!!.

Multiple incidents and multiple trips to dealership with nothing resolved. Abs activates with vsc lights at low speeds when reversing out of driveway, driving slowly down road, etc. . . No reason I can think of for it to engage. Vehicle makes a loud grinding sound and feels like it won't stop. Very common issue from what I see already reported. Yaw sensor replaced to fix another vsc issue when making left u-turns. . . Almost got in accident when the brakes kept me from completing a u-turn with traffic coming. . . Luckily I continued into driveway without incident. This happened after the above but the above still continue to this day so it was not the cause.

Tl * the contact owns a 2001 Toyota Sequoia. The contact stated that while driving 70 mph, the vsc warning lamp illuminated. The contact mentioned that when the failure occurred the steering wheel locked momentarily. The vehicle was taken to the dealer. The technician diagnosed that the ecm needed to be reprogram. The vehicle was repaired and failure recurred shortly after the leaving the dealer. The vehicle was taken back to the dealer and the technician stated that the yaw rate sensor was defective and needed to be replaced. The manufacturer was not made aware of the failure. The vehicle was repaired. The failure mileage was 143,000 and the current mileage was 144,000. . . Updated 08/11/14.

Vehicle almost lost control during a 25mph turn in light rain condition. The vehicle has brand new tires as well. This is a known issue with many Toyota Sequoia vehicles and Toyota refuses to acknowledge fault. The failure to announce a recall on the vsc pressure sensor unit will cause the vehicle to lose control, skid, loss of abs and subsequently lead to crash.

I have a 2002 Sequoia, a couple of weeks ago while driving at 35 mph my brakes locked. I took it immediately to my brake guy; he looked it over, put it on the machine, found nothing. I left thinking it might have been something on the road that I missed seeing, that set off the traction sensors. A week went by without incident before it happened again; this time at 40mph on a flat clean highway. The trac off, vsc trac & the slip indicator light came on while the front end shook violently and pulled hard to the right. I was unable to adjust the brake, as it felt locked and my steering column, while vibrating madly was near impossible to turn, it was like driving an old style truck without power steering. I went to another brake shop, they hooked it up to the machine, and again nothing showed up!! today, five days later, while driving home with my children on a major highway doing the posted 65mph it happened again. I was suddenly unable to maneuver my vehicle, the brakes locked, the steering locked, and my vehicle pulled to the right. I just held on and prayed as my car pulled off the road, thank heavens the ground was flat. I have only been that afraid for my family's safety once before, and that was in the middle of a tornado. Toyota has a serious problem here!.

Since the date indicated (Nov. 29,2013) the track off lights and system in my Sequoia gets activated without road conditions which justify it. I felt a strong noise and lost power and had a dangerous situation because of the sudden stop or loss of acceleration. Took it to Toyota and told sensors and computer needed to be replaced at great cost , but with no guarantee of definite solution. I believe this is a safety issue involving anti- skid and track system which need to be attended to promptly. Can you help?.

Vsc lights are on all the time, and so is the check engine light. Have spent $$$$ of dollars replacing oxygen sensors, mufflers, hoses, etc. Just had the frame replaced under recall, but too many other parts rotted and had to be replaced as well for additional costs. I love the car, but when I brake the wheel vibrates too much and make controlling the car difficult. I believe this is due to the vsc control. Not to mention the car stability light goes on and off everytime I accelerate (taking the SUV in for that voluntary recall as well). Fix this vsc/engine light problem.

I am having problem with my Sequoia vsc trac sensor lights turning on and off and hearing grinding noise when it auto-engage and disengage.

The vsc lights and traction lights have been randomly coming on since we purchased the Sequoia in 2005 with approx. 80k on it. They typically go off on their own and do not cause any issues. Now the slip indicator light comes on, flashes and beeps while locking up the abs and making it impossible to move until it comes to a complete stop. We have been fortunate that this has only happened at low speeds and not caused any accidents yet. It apperars that this is a wide spread issue with a combination of parts starting with the vsc computer, yaw sensor and steering angle sensor. Hopefully Toyota will take care of this due to the overall safety concern.

Cornering at about 65 or so on hiway. Sensors went off, terrible grinding noise, shaky steering.

Normally happens at low speed while accelerating. The skidding car symbol flashes, a warning beeper beeps several times, there is a noticeable swerve to the right accompanied by a grinding noise. The, trac off and the vsc off, lights come on and I am able to continue merrily on my way unannoyed, there is no apparent reduction in braking ability or steering control. I just have the "idiot" lights on the dash until I turn off the ignition. When I next drive the vehicle I am very wary until it happens again, maybe immediately, or 10 to 20 miles. But it always happens. The dealer says a new yaw rate sensor and vsc ecu will fix it. About $1800. 00 above the $105. 00 already paid for the diagnostic fee. What really gets my "goat" there is a recall for the "early" 2003 models for this same problem.

Driving on dry road and vsc engages. Can not use brakes. Continues to do this for a few minutes then stop, then engage again. Happened in oct. 2011 had a steering sensor replaced advised by Toyota and it is doing it again. This is very unsafe because I had no control of vehicle while this is engaged. I was going maybe 10 mph when it happened. No warning just engages.

Recently had new tires installed, while accelerating up freeway on ramp I could feel power being taken away, looked down and skid control light was lit up. Asked mechanic about it and recommended zero point calibration to rest sensors for steering yaw and pitch. After zpc vsc trac and vsc off lights were on. Code pulled c1231 steering angle. Zpc again. Code and lights still, code will not clear with Toyota intelligent 2 scanner. Monitoring steering sensor with scanner show both positive and negative numbers with zero at wheels straight. Mechanic want to change out spendy vsc cpu and translate cpu and says that is no guarantee to fix. I am driving it with lights one due to unable to pay $2k for something out of know where and no part physically broke to promote. In looking around I see this is not an isolated issue.

The contact owns a 2001 Toyota Sequoia. While accelerating, the contact stated the vehicle would automatically trigger the abs system at any time, causing the brakes to lock . The dealer diagnosed that the variable skid control or yaw sensor needed to be replaced. The manufacturer was not notified of the failure. The vehicle was not repaired. The failure and current mileage was 114,000.

My 2002 Toyota Sequoia has a defective sensor for the vsc, brake system. I see where the 2003 Sequoia is covered, but not the 2002's. Please tell me why this is the case, when the same problem is occuring.

This occurred approximately April 2010, upon receiving a recall notice from Toyota on brakes, I took the vehicle into the Toyota dealership. They fixed the recall notice and I ended up having to pay for a test to find out what was causing the vsc light to come on. The dealership said that there was nothing that they could do for me except replace the yaw sensor for almost $800 dollars. This was the sensor for $685 and then the labor. To this date (07/14/2013) Toyota has done nothing to fix the issue. I have read numerous issues with this item. I guess it will take someone else being killed for them to get their act together and fix it.

Veh. Toyota Sequoia 2003,the vehicle skid control (vsc) and traction control (track) lights remain on also the eng. Light. And the diagnose system doesn't have any code related to the abs. Because of this the anti lock brake syst. Doesn't work. The codes shown are related to the oxygen sensor and m. A. F. Sensor, we change all 4 oxg. Sensor and the maf and still the same condition. The Sequoia has 47,000 miles.

The vsc track, trac off and emergency light of my 2004 Toyota Sequoia,came on, on about October, 2009. I took it to the Toyota dealer, they told me that I had to replace, oxygen sensors, a new battery, and skid control computer. Total more than $2000. 00. I was told that if I don't replace the skid control computer, my break system can fail and consequently loose control of the vehicle. It sounded like a major defect and expensive repair and I was puffered as to why there wasn't any recall on such problem. After the car was serviced, the vsc track, track off, and emergency light came on again in less than a week. . This time the computer told them that :there was air in the fuel system. This is their remedy for "I need to close and seal the fueling cap after each fueling. " I do seal the fuel cap everytime after refuel. I don't recall that I ever miss one time. They reset the system and sent me off. I was wondering if the first repair was ever necessary, maybe the skid control computer never failed. It was just air in the fuel system.

In Feb. 2009, while driving to work, the brakes on my Sequoia began to lock and the engine started making a loud grinding sound and sensor lights began to blink uncontrollably. I could not control the car steering and was lucky that I was able to pull over the side of the road. This problem continued and I took it to my Toyota dealer who charged me $2700. 00 and blamed the problem on rats. After picking up my car from the dealership the problem continued a few weeks later and the same dealership still insisted that it was rats and charged me an additional $2300. 00. Yet this problem persisted so I took it to a local mechanic who has no ties with Toyota and he replaced a computer sensor. The problem went away for at least two years until recently during a recent rain storm it started to act up again. Driving this car has been unpredictable and scary at best. I came into several close calls with other vehicles on the road while driving when my car would loose all ability to steer and my brakes would lock during several instances. The experience has been a mind game and has taken a toll in my confidence in driving because I believed my dealership when they told me it was not the car, but because of rats, which I now know after reading other customers complaints on line that it was the way the car was manufactured. I lost a lot of faith in my Toyota dealership here in guam. I need your help to tell these people to recall my car to fix it even though it is 12 years old. I spent a lot of money when I invested in this car and I don't have the money to buy a new vehicle at this time. I am afraid an accident will occur to customers like me unless Toyota admits they have a problem with their vehicles.

While driving at a rate of 70mph the vsc trac and trac control warning lights came on. The car decreased in speed and veered to the right, causing me to momentarily loose control of the car. Per owner's manual took car into dealership for diagnostic. Per codes obtained via diagnostic dealer suggests replacing yaw control sensor and ecu. After researching this issue myself it seems to bean issue with the 2001 Sequoia and its ecu, yaw control sensor, and the steering angle sensor that could result in serious harm or injury if not corrected.

The contact owns a 2001 Toyota Sequoia. While driving 65 mph there was a loud thump in the right front passenger side wheel area, automatically the right front brake was applied . The vsc off and traction lights illuminated on the instrument panel. The contact depressed the brake pedal and released it, which allowed the front passenger side brake to release and the vehicle to drive normally again. Four days prior to the failure, the contact noticed that the vsc off and traction lights would illuminate while driving, but then dim after the vehicle was restarted. The vehicle was taken to the dealer and they disabled the vsc sensor to prevent the failure from recurring. The current mileage was 47,000 and failure mileage was 44,700. Updated 09/10/08.
