Problems with 2001 Toyota Sequoia VEHICLE SPEED CONTROL

Vehicle: toyota sequoia 2001 4wd ltd temperature: 87 degrees f conditions: sunny & clear - no rain/water present - no obvious slippery conditions surface: paved surface road accessories active: air conditioning was on & radio was on while traveling at approximately 35 mph in a straight line the traction control light illuminated (vehicle symbol that includes 3 wavy lines) and sounded an audible signal immediately followed by the "vsc trac" & "vsc off" lights illuminating. to memory, the accelerator pedal was being pressed as normal. when the above dashboard lights illuminated a negative sensation could be felt through the steering wheel, but the vehicle did not veer off course. next, the emergency flasher hazard light was turned on, the a/c & radio were turned off and the four main windows were lowered to their full down positions by the driver and the vehicle was driven to a side street approximately 1/8 mile ahead, stopped and parked. the driver kept the vehicle running. the vehicle was then inspected by the driver for signs of obvious mechanical failure. the brake, driveline and suspension components did not show any obvious signs of failure. the owner's manual was checked and it did not indicate that the vehicle could not be driven in the current state. the vehicle's a/c system was switched back on (the radio was left off) and the vehicle was then driven approximately 10 miles, parked and turned off. after approximately 4 hours of the vehicle being parked & not running the vehicle was restarted. the previous dashboard lights at first did not illuminate. after approximately 1/4 mile of driving the "vsc trac" & "vsc off" lights illuminated again upon depressing the brake pedal. vehicle was driven approximately 50 miles, parked and turned off. there were no unusual mechanical sensations felt or heard during either 10 or 50 mile drives. *tr

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. *tr

Abs, trac control, and vsc light come on intermittently all at the same time. there is a total loss of abs and traction control - very scary on icy roads. problem comes and goes. cannot seem to get a fault code. based on the postings i see, this is a known problem. *tr

Sudden loss of acceleration on highway. vsc and trac light came on, then could not accelerate. had to pull over extremely fast before getting rear ended by other vehicles. can would not accelerate at all. check engine light came on as well. extremely dangerous condition and could have been severely hurt with entire family in car. luckily there was a shoulder to pull off on, otherwise, we would have been in an terrible accident. car was not safe at all! toyota needs to know about this vsc issue! *tr

Driving my recently purchased 2001 sequoia and the vsc system goes off like we're on ice. does it until the system stays off. it has been doing this randomly. very scary... recall needs to be done. *tr

Vehicle vsc lights come on and cause a tempoary loss of power . the vehicle front ends also starts to shake which cause a tempoary loss of controll. this started 6 months ago and is happaning daily. *tr

The sequoia vsc trac,vsc off sensor lights turning on and off and hearing grinding noise,and lose power. and the roll over system light come on. *tr

Was driving down major interstate when the vsc warning came on with buzzer. brakes felt like they were being ground down, engine decelerated, and could feel bumping and grinding on brake pedal. pulled over and checked under car, found nothing. got back on interstate and same thing happened only this time the system turned itself off. can not turn the vsc off with the button provided. research on internet reveals not an unique issue with sequoia. has also happened with tundra and other toyotas with vsc system. no fix available as of 07/30/2012 that can be found. *tr

My 2001 toyota sequoia traction control system/vehicle stability control system (vsc) or anti lock braking system (abs) seems to be failing. this problem started about a year ago. the problem is an intermittent ratcheting or grinding noise coming from the front of the vehicle which causes the wheels and steering to vibrate immensely and have feelings of lost control (stalling) while driving. this has occurred at all different road speeds and conditions. *tr

I was driving my 2001 toyota sequoia today when the vehicle skid control (vsc) activated for no apparent reason. i was at freeway speeds on the flat, level freeway. the car suddenly lunged forward and pulled hard to the right forcing me partway into the next lane. this is not the first time this has occurred either. the problem is widespread when i searched for an answer on the net. i am telling you, this will kill or seriously injure someone if it hasn't already. this needs to be addressed by toyota. they initially ignored the accelerator pedal complaint too as operator error. this vsc turning on by itself has happened to me about 6 times in the last 18 months. i have replaced the expensive yaw sensor and that did not fix the problem. *tr

In the last 6 months my 2001 toyota sequoia vsc (vehicle stability control) system has engaged unnecessarily without reason. the system engages on dry roads going 65-70 mph. the first time it happened it almost caused an accident since it is unexpected and feels like vehicle is loosing control when the brakes lock and the steering curves to the right. this has happened a half dozen times. i have researched the problem and it seems toyota is only recalling 2003 year models when in fact the problem is on various model years...old and new. im concerned that this defect will cause a serious accident or death. toyota needs to take responsibility for this and have all model years recalled. *tr

Vsc / trac system engages randomly... sometimes three times per week. started about one month ago. various speeds, various circumstances... nothing consistent. it has pulled me off the road twice, but most of the time just engages with a rumble sound and hard to drive. the computer diagnostics finds nothing. i have used auto-blog and discovered dozens of people with the same problem. *tr

My 2001 toyota sequoia traction control system/vehicle stability control system (vsc) or anti lock braking system (abs) has failed. this problem has just started to occur summer 2010. the problem is an intermittent ratcheting or grinding noise coming from the front of the vehicle which causes the wheels and steering to vibrate immensely and have feelings of lost control while driving. this has occurred at all different road speeds, specifically it has occurred while i was driving at full highway speed of 70 mph. the reason i mention both the vsc and the abs, is that these two systems are interworked for control, and at this time it could be either or both which are failed. *tr

My 2001 toyota sequoia traction control system/vehicle stability control system (vsc) or anti lock braking system (abs) has failed. this problem started last summer 2009, and now this problem has become consistent and at every acceleration from a dead stop. the vehicle stalls momentarily and the vsc light/s come on the same time. the reason i mention both the vsc and the abs, is that these two systems are interworked for control, and at this time it could be either or both which are failed. *tr

The vsc light comes on while driving, alarm beeps, grinding noises an difficulty stopping car. this happened at 35 mph the first time on dry road. contacted dealer and they suggested to just pull over if it happens again and bring car in. second time it happened at 65/70 mph on highway. had to pull into break down lane, came to complete stop, while driving in breakdown lane to next exit, happened again. brought to dealer in area, could not find a problem. brought to dealer where car is always serviced and they cannot find the problem either. both incidents were very scary and felt like the vehicle was not going to stop. due to pick up vehicle from dealer tomorrow but have printed out numerous similar complaints to show the service department. *tr

Tl * the contact owns a 2001 toyota sequoia. while driving approximately 70 mph, the contact applied pressure to the accelerator pedal and the vehicle began to decelerate. the vehicle trac control, and vehicle stability control warning lights were illuminated. the warning indicators remained illuminated until the engine was turned off. the failure occurred whenever the vehicle was in operation at any speed. the vehicle was taken to an authorized dealer where the technician recalibrated the yaw rate sensor. the failure continued after the repair. the vehicle was taken to an authorized dealer for a second time and the yaw rate sensor was replaced. the failure mileage was approximately 128,000. the vin was unavailable.

My 2001 toyota sequoia had a problem where the abs and vtrac light would come on and the vehicle would violently pull to the right side and you would loose traction and control. this happened numerous times and was taken to the toyota dealer for repair. they reloaded the computer program because the computer was not logging the codes. the next day the same thing happened and i took it the dealer right away and they were able to get a code and determine it was a yawr sensor.the sensor was replaced on 6-10-10 and seems to have fixed the problem at a cost of $455.46 plus $100 to reprogram the computer. this seems to be a regular problem with this vehicle and it should involve a recall before someone get seriously injured or killed. *tr

My 2001 toyota sequoia has had issues with the vsc/trac lights coming on and then the skid control lights come on forcing causing power to go out while driving in the middle of the freeway. it was very dangerous. i managed to pull to the side of the road and wait to restart the vehicle. when it cooled off, i was able to drive it a little farther. the dealer says it is the yaw rate sensor and it will cost $670.89 to repair. but i have been reading it has happened to others. they just have not complained about it. *tr

Vsc/trac lights come on and stay on my 2001 toyota sequoia - appears to be a common problem and is a potential safety hazard with the stabilization computer possibly going out. *tr

The vsc and other lights in dash light up and has caused the vehicles brakes to engaged without warning. its pulls the steering wheel violently to the to left. it happens at high and low speeds. went to dealership and they said it was the skid control computer and the cost to replace it is 1,200 dollars. *tr

Tl* the contact owns a 2001 toyota sequoia. the contact stated while driving at approximate speeds of 30 mph, the vehicle abnormally decelerated to speeds of 5 mph without warrant. the vehicle had not yet been taken to the dealer for a diagnosis of the failure. in addition, the contact stated the electronic stability control exhibited unknown signs of failure. the approximate failure mileage was 31,000 and the current mileage was unknown.

Vsc, abs, trac, and brake warning lights all on constantly. when first observed, only occurred during cold weather. lights did not come on when weather and car was warm. starting 2010, these warning lights have constantly been on. toyota dealer seemed unsure of problem, but suspected that vsc computer needed to be replaced at a cost of $2500. *tr

The throttle stuck in the closed position while we were traveling on the highway maintaining 65 mph. the vsc and engine lights came on. there was suddenly no acceleration and response from the pedal so we came to a stop on the side of the road with the car in drive and the engine still on. i had a near collision when this happened a week prior in the middle of an intersection and the acceleration was lost. this is fixed temporarily by turning the engine off and back on again 5 minutes later. i had to get the whole throttle body replaced. this happened at 85,000 miles. this happened with the same vehicle at 48,000 miles 3 years ago and they seemed to fix it by cleaning the throttle control sensor really good. i've seen reports of others experiencing this as well on line. this should be a recall item...thank god we are still alive! *tr

Appears cars stability system came on with application of brakes, noise on the brakes. weather was clear. vsc, track light came on. happens every few weeks. *tr

Ecu computer and traction failure in 2001 totota sequoia. *tr

I have a sequoia which i bought brand new in 2001. for all my services i take it to atlanta toyota in duluth, ga. recently my vsc trac and vsc off sensor light turning on and off and i'm hearing grinding noise when it auto-engage and disengage. my dealership was asking about $1300 to fix this problem and they have all parts in stock i'm not sure whether it is vsc computer ($1500), complete breaking system, or yaw rate sensor ($550 + $95 labor) since this is a safety issue because the vehicle loses all power momentarily. i would like toyota to take care of this problem for me, since i'm such a loyal customer. i am surprised and pretty disappointed that this problem has been seen all the way back to the first model year till 2005. toyota could have figured out a permanent fix by now. atlanta toyota told me about leaky/defective brake booster $1400 repair. *tr

The car slowed down to 40mph while i was doing 65. mechanic said the throttle body assembly is not working properly. i escaped several accidents while i was driving, the brakes had became loosed, and the steering wheel became very hard to handle. the car started jerking, and almost ran over. i went to llehman toyota on 441 north miami beach, they charged me 1800 dollars to fix the censor, and the steering wheel assembly. now, the same problem repeats. *tr

Vsc/trac light has been coming on intermittently for one year with no ill effects until yesterday when the vsc system activated itself twice under perfectly normal driving conditions. the first time it happened i was braking normally when the vsc kicked on and limited my stopping ability. the second time the vsc activated was i was driving 50 mph, foot off the brake, when the vehicle began pulling hard to the right forcing me into the next lane. for the few moments this lasted i had no control over braking or steering. dealer has yet to resolve the issue. *tr

Tl*the contact owns a 2001 toyota sequoia. the contact was driving approximately 40 mph in rainy weather conditions. an increase of acceleration occurred without warning. suddenly, the vehicle steered into another lane due to a loss of steering control. the vehicle continued to accelerate and crashed into a wall; another vehicle rear ended the vehicle. the vehicle was completely destroyed with injuries to the driver and passenger. a police report was filed. the failure mileage was 70,000. updated 4/26/10 *cn updated 05/11/10.*jb

I purchased a 2001 toyota sequoia in april/01. i don't recall any problems until about may/04. the vsc light kept coming on and the car wouldn't have any power for about 30 seconds. i informed the dealer about the problem and was told that the car was passed the warranty and i would have to pay out of pocket to have it looked at. i didn't have the money so i just dealt with it. well about 5 months later, the brake would engage causing a grinding noise thus making the car pull to the right without any warning. even now i drive down the interstate going almost 70mph and it does it. if i didn't have a quick reaction time, i'm sure i would have been in an accident by now. all of this happens on dry roads while going straight. no reason for the vsc (traction control) to engage. toyota really should be forced to do a recall on this. i have read a lot of complaints about this problem. *tr

The "vsc off" and vsc skid lights came on and has remained on to the present date. when the lights came on all vsc functions stopped. vehicle was taken to the dealership. repair was not under any warranty. an estimate of approximately $2200 was given to replace the vehicles ecu. no repair was made. occasionally the vehicle would lose power under moderate acceleration for a brief period (usually less than 2 seconds) as if something has cut power 20-30%. i suspect it was the vsc system trying to cut on or engage. this has not happened for some time. vehicle now has 178000 miles. *tt

2001 toyota sequoia- 48k miles..vehicles traction control and vsc lights come on shortly after driving the car. just before the lights come on, the car shakes and makes a grinding noise, pulls to the right, and loses power. this occurs every time you drive the car. anywhere from 1min to 15min from the start of driving. it is very dangerous once the vehicle is up to speed, we have almost gotten in to an accident because the car pulled so violently and didn't have power. the car will shake and pull and the only way we've gotten it to stop is by stepping on the brake and reducing speed (less than 30 mph). after we reduce the speed, the trac and vsc lights come on and the car is drivable until you cycle the ignition. it's pretty scary. my father-in-law took the car to a toyota dealership and their diagnosis is skid control ecu faulty, must replace. dtc codes c1363 and c1234. the cost they quoted him was $2415.99 + $200 labor. we haven't decided to purchase the new ecu because we feel its something that should be covered under a warranty or should be a tsb. i've since searched the internet and found that other sequoia owners have the same problem and toyota's response is to just replace the ecu. some of them even got into accidents due to the sudden loss of power and shaking. *tr

On my 2001 toyota sequoia, the vsc/abs/skid light came on a few days. we took it to the toyota dealer and they indicated that the vsc/abs skid control ecu has failed. we are told that we need to replace this at a cost of $2,400. i understand that there have been numerous reports of this problem, catching fire, etc. and this problem is life threatening. i feel that toyota should step up and fix this problem without charging me. *tr

Violent shaking of vehicle while merging onto a major highway at 65 mph. failure of vsc on 2001 toyota sequoia. replaced 3 parts....yaw sensor, brake booster and cpu. old cpu part is in my office. spent close to $2000 on repairs and toyota's hq in california response was "out of warranty". *tr

I have a 2001 toyota sequoia auto sr5 and there are 5 lights on steady. the vsc,track,stability,abs, and brake lights. the lights have been on for a few years. the car drives fine, but the abs and the track does not work. the power brake booster has been changed, with no help. i have called the dealer, but have not been there because of the money they want to check out the car. from reading on the internet, the problem sounds like a vsc unit. i scanned the car, and there are no codes. i understand that there might be a recall on the vsc unit. the dealer says no, but i am filing a complaint about safety because the vsc and the abs does not work. thank you for your time. *tr

Owner of 2001 toyota sequoia that infrequently has an issue where out of nowhere the vsc device activates. the vehicles front left wheel starts to grind and you can hear the device going frantically until it stops on its own. normally it is brief and the 'vsc off' light comes on, but there have been times where it has happened at high speed causing distressing situation. toyota dealer inspected the vehicle and stated that it could be a defective control module, but they couldn't find an obvious cause. they cleaned the sensors at the wheels and where the connection hooks to the dashboard for vsc off button. i wrote toyota in hopes that they would offer assistance, but they responded with the terms of the warranty and that there was no issue. *tr

Vsc trac warning light intermittently comes on while driving. if you turn the car off and then back on they go away. i took it to the toyota dealer several times under an extended warranty and they could never get it to fail. they told me to come in when it is failing and they could then look at it. this has been going on intermittently for years now. i am concerned that it will finally fail completely and may cause an accident. way to many of these sequoia's are having this same problem for this to be an isolated issue. toyota needs to step up and fix this as it is a safety issue. tr

Tl*the contact owns a 2001 toyota sequoia. while driving 50 mph, the versa-track stability control lights illuminated. the dealer has not inspected the vehicle. the failure occurred intermittently. the dealer inspected the vehicle approximately six months after the first occurrence. as of july 9, 2007, the vehicle has not been repaired. the current mileage is 116,000 and failure mileage was 106,000.

2001 toyota sequoia. when i shifted from reverse to drive the engine roared to a fully racing engine and accelerated forward. hard braking could not slow the vehicle and it hit the back of a 2004 honda mini-van that was parked, doing extensive damage but causing no injuries. *jb

I have a 2001 toyota sequoia, purchased used in 2004. in 2006, the abs,vsc,brake lights began to light up intermittently. after a few months, they came on & stayed on. the dealer did a diagnostic test and said it was a computer problem and would cost $2500+ to fix. this seems like a major design flaw by toyota, and causes an extremely unsafe condition. i would expect a recall due to the number of similar complaints.

Vsc light was coming on intermittently. vehicle(sequoia) was still under warranty so the dealership replaced the skid control ecu. the vsc light started coming back on intermittently approximately one year later. since the vehicle was out of warranty toyota said it would cost approximately $2400 to fix. since the lights only came on intermittently without any other problems and i didn't have the money to spare i didn't get the repairs done. while having my rotors turned at the dealership the mechanic said they noticed the vsc light was on. they said they worked on my vehicle for 3 hrs(at no charge-just doing me a favor)) to try and remedy the vsc light problem. when i left the dealership i got on the highway and not 2 miles down the road the warning lights and abs lights were coming on, i started hearing warning beeps, the car started vibrating violently and pulled to the right. scared the heck out of me! i pulled over and had the car towed back to the dealership. of course the dealership said it was skid control ecu and would cost $2400 to fix the problem. i have taken excellent care of this car and would fix it if i didn't think it would happen again. because of necessity i have been driving the car and dealing with the daily scare but lately it has been getting so bad that i will probably have to trade it in before it causes an accident. *tr

Unexpected acceleration on a 2001 toyota sequoia registered to a mother of 4. incident occurred on i85 at mile-marker 104 in broad daylight with clear, dry conditions. with recent revelations about toyota hidden safety around unexpected acceleration, this is the only explanation that makes sense with regards this fatal accident. *tr updated 03/14/10 *bf according to the police report, the right front tire of the vehicle ran off the roadway to the right onto the rumble strip. the driver over corrected and swerved to the left, losing control of the vehicle and crossing all three lanes of travel. the vehicle ran off the road to the left, striking a plastic construction barrell. the vehicle began overturning in the median and struck the median guardrail cable. updated 06/17/10. *jb update 9/19/2011*cw

While applying the accelerator pedal vehicle cut the throttle back from idling. this caused the wheels to spin, then vehicle moved forward on its own, and stalled. consumer restarted vehicle, and drove it to the dealer for inspection. dealer informed the driver that vehicle was operating as designed, but it was unsafe to operate it. *ak

The vsc light came on after my 2001 sequoia hit a pot-hole. this was back in 2004 and the light remains on. i was told it was a sensor. the vehicle is long out of warranty and i can't afford any expenses right now. that's just one of a few major components to go. in 2003 the torque converter went and the transmission had to be replaced. i had 88,000 miles on it and it was beyond the 60,000 drive train warranty. however, toyota did pay for half of the $4000 bill with the dealership picking up a 1/4 of the bill. i paid the rest. was paying half an admission by toyota that they provided a faulty transmission. i do know that the dealership removed the old transmission and shipped it off to toyota and i never heard another word about it. the brakes on these big vehicles have been a sore spot with me. i've had to change brakes and rotors numerous times over the years. and last on my list of complaints is the tailgate. it has rusted out prematurely and it is more than a $1,000 to replace. i use bungies to keep it closed up and i had to prop the window up since the tracking system in the tailgate rusted out and fell apart. *tr

Vsc light illumination/failures initially appeared at 42,000 miles, very intermittent and seemingly random. frequency increased after 75,000 miles; abs light appeared later. 1. vsc off light illuminated (variable speed control) initially at intermittent time while driving, now illuminated full-time. 2. vsc trac light illuminated (variable speed control) initially at intermittent time while driving, now illuminated full-time. 3. abs light illuminated (anti lock brakes) initially at intermittent time while driving, now illuminated full-time. abs now inoperable. tested to validate inoperable status - full brake lockup, no abs operation. variable speed control now inoperable. spun out twice recently in slow speed right hand off-camber turn on wet pavement.

Vehicle occasionally lurches forward when in gear with the brake pedal depressed. vehicle traction control engages and will not allow the acceleration in heavy traffic conditions. *tr

Vehicle skid control light, abs, and vsc off lights come on. get grinding noise from right front wheel as the abs applies the brake and steering wheel and vehicle pulls extremely to the right. almost loose control of vehicle if your not expecting it. this happens on dry pavement. *tr

We have a toyota sequoia, the problems are the 4 wheel drive is not operating all the time. it does not engage, when it does sometimes it does not stay in 4 wheel drive. one example is when my wife had six friends in the vehicle the 4 wheel drive did not stay engaged and the vehicle skid control made the engine loose power so she slid backwards down a hill. no one would ride in our 4 wheel drive again. the vehicle skid control activates at radom on dry pavement. the skid control makes the engine loose power while in traffic. there is also a hesitation in the engine when accelerating from a complete stop. another problem is the braking system is anot adequate for the vehicle. the entire front brakes had to be replaced. the vehicle has been in for the same reairs at least five times and is still not working the way it should. we have all the documentation for service on our sequoia. we have done internet research through the nhtsa and have found the same problem with other toyota sequoia's.

Tl*the contact owns 2001 toyota sequoia. while driving 70 mph, the vehicle slowed down rapidly without warning while he depressed the accelerator pedal. the dealer was unable to duplicate the failure. the current mileage was 100,000 and failure mileage was 5,000. the vin was unavailable.

When accelerating from a complete stop there was a hesitation in engine. this hesitation almost resulted in several vehicle crashes. dealership has examined vehicle, but could not duplicate the problem. informed consumer this hesitation was normal. please provide any additional information / documentation. *ak
