The vehicle was taken to the dealer and a technician concluded that the abs computer needed to be repaired at an expense of $2500. 00. No repairs were made. The manufacturer was notified, but no assistance was provided. The failure mileage was 40,000. The current mileage was 43,000. Updated 10/23/09 the consumer was informed the skid control ecu needed to be replaced. Updated 10/27/09.

I have a 2003 Toyota Sequoia limited 4x4. I have a problem with vsc/ trac light come and goes. I went to dealer when the car was under bumper to bumper warranty,dealer told me that I have low brake fluid causing that problem. But car was driven less than 20,000 miles at that time. Now car is out of warranty and I found out I have problem with computers controlling vsc. And it will cost me alot. I have found that lots of Sequoia having similar problem as mine. I like to know what has to be done for this matter. The car now little under 40,000 miles.

Failure of skid control ecu. Failure initially intermittent, but e-brake light stays on to identify the problem. Intermittent problem not identifiable, but failure prevents skid control from working.

Normal vehicle usage with only 66,000 miles and all abs, vsc warning lights are on with anti-lock and anti-skid computer disabled resulting in no abs or skid control. Dealer reports to me that it is a $2,200 "computer" needing replaced, only 6,000 miles out of powertrain warranty. Call to Toyota corporate was of no value, dealer and Toyota refuse to provide any assistance.

Toyota has a widespread problem with their vsc system. My dealer wants $1800 to fix what Toyota knows is a huge widespread problem for Toyota tundra/sequoia. This is ridiculous and Toyota needs to replace the vsc computer and engine control computer (ecc) for free. What a bunch of non-sense!.

2004 Toyota Sequoia (67,000 miles) taken to dealer for repair on 10/13/2007. Front brakes replaced and rotors turned. On 10/15/2007 check engine, vsc and trac lights came on. Vehicle was driven without incident. Vehicle taken to dealer on 10/20/2007. Dealer identified problem as skid control computer needs to be replaced. Cost $1390.

Vsc system having intermittent issues (grinding noises when engaged, inop sometimes) but has not completely died. I find the issue is very common and very expensive to fix. I believe this car has had problems before with vsc and is just a matter of time before it dies. I just bought it less than 1 month ago with 72k miles.

Trac light/vsc lights come on while driving down the road . Without warning the car jerks to the right and a grinding noise sounds like something is going to fall out from under the car. I took it to the dealership and the cost to repair is close to $3,000. How many complaints do you have to receive before something is done!.

Vsc/abs skid control ecu failure. The dealership is saying that my 2003 Toyota Sequoia limited 2 wd 53,500 miles needs a new abs computer at a cost of $3,600. Approximately 2 years ago I had the exact same thing happen, the car actually froze up and the dealership had it towed to their location to fix it, they said it was the third member and replaced that. Now the same thing is happening and they won't do anything.

I took the 2002 Toyota Sequoia in for a routine maintenance to the dealer, performance Toyota in la vista, ne and was told that the joints were recalled. The vehicle was performing well up to that time. After the service, two days later the skid light and the vsc (variable skid control) lights came on and after restarting the SUV, went off. Now the brake system is malfunctioning and the vsc is disabled. A week prior to the service the system worked just fine on the same route that I take to pick up my son while it was raining. There is a significant reduction in the vehicle control. What makes this problem even worse is that there is no indication of a system failure after the initial indicators have reset. (I. E. The lights came on and went off permanently) it was a fortnight later in the rain that the vehicle spun out of control and we realized that the vsc system was malfunctioning. Researching the problem, I find that there are many other owners experiencing the same thing. The dealer says that the responsibility to fix the problem is that of the owners. There is a need for this to be taken care of by Toyota corporation in the form of a recall as the main braking system is affected on so many vehicles.

My vsc/trac sensor has been going on and off and every time I needed to have it check, the problem never appears. Except for today, the light has stayed on and my mechanic was able to diagnosed and verified it with Toyota's TSB as a defective vsc/trac ecu and he recommended that I take it to a dealer for the replacement and installation of the new ecu. Several TSB's are posted on the NHTSA website regarding this problem for my vehicle year and make. My complaint is, I feel that it is unacceptable that a computer device that plays a vital role in the safety performance of the vehicle should not have failed within 5 years, especially for a considerable cost to have it replace after the warranty period. Toyota should have at least sent out notices to the owners regarding this potential problem.

I am another victim of the ongoing problem for 2003 Toyota Sequoia, vcs traction control light on. So this past weekend being on a trip the light come on and we took it to the dealership and gaves us a surprise repair $1,448. 50 for part 89541-0c062 and 896300c011 $751. 54 so with labor some in the 2,500 dls. So I told the service guy what was the risk of driving this unit like that. In my own words is like having an 1980's suburban. My husband did a research on the internet on tundrasulutions etc. And there are a lot of cases of this problem arousing around 40,000 miles or less. We have a 4 year old son and we are "scared" to drive this truck without of any of the safety features now I was told that the traction control computer and the main computer needed to replace and that this will disable abs and traction controls. So this means that I have a 1980 suburban. We are very upset because we call Toyota and they can't do anything about it, they refer me to the dealership service manager that probably can offer me a discount outside warranty. We need NHTSA to start investigating this issue there are thousands of users that already paid for this repair that don't even know how to file a complaint. Don't let this issue get out of hand, please don't waint until there are people hurt. My truck is worth around 14,000 the repair is 2500 the repair is 18% worth of the whole vehicle. Toyota knows about this problem if they sell a car with defective parts they should replace it.

While entering a busy intersection my wife applied the brakes to avoid a collision, and they did not properly respond and dashboard warning lings came on. The Toyota dealership diagnosed the problem as a defect in the car's computer system, stating the computer provided false signals to the brakes.

Vsc control unit failure on 2004 Toyota Sequoia. The vsc off light is on as well as the check engine light. Told it is a $2000 fix by the dealer.

Vtrac failure indications while driving my 2003 Toyota Sequoia. 66,213 miles. Had this checked while under warranty at 30,000 miles but it was not a hard failure so it was called intermittent. Current failure clears after ignition cycled but dealer says fail codes do exist that show computer is failing. Toyota has a service bulletin to replace computer if under warranty. Research on the internet showed countless failures of vtrac computer on this model and the tundra with the full failure causing vehicles at high speed to go from 70 mph to 1 with no power assistance and uncontrolled deceleration. Toyota is aware but doing nothing to remedy except repair if brought in at owner expense if not under warranty.

Vsc trac/vsc off lights intermittently turns on, regardless of driving condition, speed or weather.

My traction control, skid control, and abs warning lights continued to light up intermittently on my 2004 Toyota Sequoia. While the warning lights were on, the brakes would suddenly grab, make a terrible noise, then bring the car to a quick and sudden stop. I narrowly avoided 2 different car accidents because of the car suddenly stopping. I took the car to both a Toyota dealer and an independent car repair shop specializing in Toyota cars. Both reported this was a well known problem and that they had to repair this problem on 5 - 6 Toyota Sequoias per month. The diagnostic codes reported from the car's computer included co215 (lr wheel speed sensor malfunction), co1223 (brake pedal stroke force sensor malfunction), co1247 (abs system malfunction), and co1310 (solenoid circuit malfunction). The repair shop replaced both the abs/skid control ecu and active booster solenoid for a total cost of $2410. If this is a well known problem, why has Toyota not implemented a recall for this issue. It is a very dangerous condition affecting a large number of vehicles.

Vsc/abs/traction control computer failed.

Braking system module.

(1)the dashboard lights for abs, vsc, & traction control flickered, and then remained on permanently. (2)the abs and vsc have malfunctioned which seriously affects the braking & stability control of the vehicle in emergency handling situations, endangering person(s) in vehicle. (3)right Toyota in az could not determine problem, although technician stated this was a common failure of the 2002 Sequoia.

1) overly sensitive trac computer will cut power when merging into traffic, causing a potential situation for an accident. 2) trac-off and vsc-off lights will illuminate, fault codes show that vsc computer needs to be replaced, leaving the vehicle without traction control or stability control or abs brakes. Manufacturer will not cover unless still under bumper to bumper warranty. Happens at least once per week.

My vsc & track off lights will not turn off. I lose control of my car at about 5 miles per hour due to this problem about once every other day. Toyota advertises this break system as a safety feature on their website, yet dealership says it's not a safety issue. The dealership told me that the computer controlling this has failed & needs to be replace at a cost of $1300. My car is not yet 3 years old but just out of mileage warranty, so they said this cost was up to me to pay. My mother owns the same model & year Sequoia & the exact same problem happened to her car & the same dealership fixed her problem at 36k miles but won't fix mine @ 46k b/c I'm out of warranty. My husband's employer had same problem at 40k miles on his 2003 Sequoia & had to pay for the repair. I know personally 5 families who own Sequoias & 4 of us have had the exact problem. The 5th just bought their car 4 months ago, so we are just waiting for their problem to occur. I'm meeting with the district factory rep tomorrow & will bring up the number of complaints on this website about the vsc computer failure.

I bought a "Toyota certified" 2002 Toyota Sequoia in late '04. Roughly 6 months into ownership - my vsc (traction control) system began having intermittent issues - 2 full-day trips to the dealership made no results - the dealership was unable to recreate the problem. Another 4-6 months later, the vsc failed completely, and after investigation, I find the issue is very common and very expensive to fix. The failure leaves me without abs and without vsc (two of the reasons I bought the car I did) and at an increased risk of having an accident, as without functional abs the brakes lock quite easily. Calls to my dealership have left me with the impression the fix will be in the $2000 neighborhood, and I haven't yet come up with that. The incident date is approximate to the start of the issues.

Traction control system (vsc/trac) will intermittently not function for no apparent reason, causing vsc/trac lights to illuminate and potentially compromising vehicle safety. Diagnostic check of vehicle reveals a problem with the brake booster and/or a sensor within the brake booster assembly that is prone to intermittent failure on this vehicle. Replacement of the parts in question are prohibitively expensive (over $1,000) and only covered up to 3yr/36k mile on the vehicle. There is a definite failure trend present in this particular vehicle and Toyota knows about them, given the tsbs that exist for this problem. This issue needs to be addressed as a recall to ensure all vehicles, especially ones out of warranty coverage, are repaired properly.

The brakes were defective. While merging onto the highway the skid light came on and the brakes were applied. Vehicle would not accelerate, then, it suddenly picked up speed. Vehicle was serviced one year ago for the same problem. A computer sensor was defective.

Vsc dash light ("idiot light") has been consistently on now for the last 10,000 miles (current odometer = 51,000 +/-). The light was on intermittently starting before the vehicle was 1-1/2 years old (<25,000 miles. ) in addition to the vsc light, the 'brake' light stays on (originally illuminated only when the parking brake was engaged. ), plus the abs light is consistently lit. The vehicle was taken to Toyota more than once with the vsc/abs/brake lights complaint, but Toyota was unable to diagnose any problem until a service performed after the 36,000 mi warranty expired, at which point the dealer thought an abs computer replacement might solve the problem. The dealer did not acknowledge any problem until after this 36,000 mile point despite intermittent events occurring very early on.

Anti- skid control system mode solenoid sensor/ abs brakes can activate at any random time. Contacted dealer, and dealer stated there was nothing wrong with vehicle. The skid control system activated five times during the first week of puchase, but had not occured since. However, the consumer does not feel confortable because of possibility of reoccurence.
