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.

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.

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.

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.

Front brakes caused violent shaking at highway speeds. Had prepared vehicle for lengthy holiday trip by inspecting and rotating tires, having wheel alignment, checking brake pads, rotors, bleeding brake lines with new dot3 brake fluid, engine oil change, coolant flushed, etc.... this was not the first incident, but definitely the worst. Toyota dealership has told me on numerous occasions that they could not fix it. How disappointing. I recently found that this is a known issue that they don't want to address. People will die as a result of their recklessness. Definitely a Toyota problem due to improperly undersized braking system. You might end up being in the vehicle that one of these SUVS rearends.

Vsc/trac control system engaged while driving on smooth dry road at 70 mph. Vehicle began to lurch and brake, had to guide to side of road. Extremely dangerous. Turned vehicle off, restarted, vsc off light and check engine light were on. Has happened multiple times since, with Toyota indicating that vsc computer needs to be replaced for $1200+.

Skid control engage unexpectedly.

- Orlando, FL, USA

Brakes intermittently apply on there own, pulling the car left or right. I am supposed to have the option of disabling the vsc on this vehicle but that function does not work. It will disable itself after an episode, later it will self enable and it starts over again. I've had it in to Toyota service to fix this issue and was told I would have to pay for a new cpu, but that would not necessarily fix the problem. I've seen other Sequoia owners have had the same problem on many Sequoia owner forums. This is a very dangerous situation for Sequoia owners. The dealer have no idea how to fix this problem.

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.

- Lovettsville, VA, USA

When traveling at any speed the two warning lights concerning the trac control on the the dash comes on and beeps several times, the vehicle suddenly brakes and pulls hard to the right temporarily losing control. All this happens in a split second with no warning. I am very concerned with my safety along with my families and others on the road concerning this safety defect.

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.

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.

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.

My wife and I own a 2001 Toyota Sequoia. On 5/21/10, the right front ball bearings failed. The brake line snapped and the wheel fell under the car. Luckily my wife had just turned onto a road and was going at a slow speed and was able to pull to the side - especially since she is 8 months pregnant. This seems to be consistent with problems that led to a recall of the same model vehicle for 2004-2007. Toyota said that this was not part of a recall and there was nothing they could do about it. It seemed important to make you aware of this as I am certain that this would have been much worse if my wife was traveling at higher speeds. It is especially disconcerting that this same issue was found in later models of the same vehicle.

Having issues with stopping a 2001 Sequoia due to undersized braking equipment. The issue is when the brake is depressed the Sequoias tires and steering wheel shake excessively. I have replaced the pads and had the rotors turned. This is know issue with the Sequoia for Toyota. Tsb issue and braking system fixed as long as the car is under 36000 miles this is a safety issue to all drivers on the road. I have had a couple near misses due to the inconsistent breaking. While at dealership (Toyota of concorde in nc they will not even acknowledge the ts"S are out there. It is an ongoing safety issue that when coupled with issues with the traction control that is going to seriously injure or kill people. As stated the brake issue has cause near misses in our SUV and other.

Front brake and rotors are inefficient and wear excessively causing the front end to vibrate and pulse under braking. The consequences of this vibration is a decrease in the efficiency of the ABS system and overall braking. Toyota has identified this as a problem in tsb BR005-02. I have replaced rotors and pads every two years because of this problem. Toyota fixed the problem in newer model years by adding larger rotors and better calipers, but has ignored this problem.

The contact owns a 2001 Toyota Sequoia. The contact was driving approximately 60 mph. The brake pedal was depressed with force. The vehicle failed to slow down and crashed into the rear end of a vehicle. There were no prior warnings or personal injuries. The vehicle was completely destroyed. A police report was filed. The failure mileage was 125,000.

- Sparks, NV, USA

The contact owns a 2001 Toyota Sequoia. Whenever the contact applies the brakes he noticed that the ABS system and traction control would activate regardless of the driving surface, the contact also noticed that he could hear a sound similar to leaking air coming from the brakes. The vehicle was taken to the dealership where the contact had the ABS sensor and all components of the braking system replaced, however the contact still notices the leaking air sound coming from the brakes. The vehicle has not been diagnosed since it was last serviced. The current mileage is approximately 138000 and failure mileage was approximately 78000.
