The contact owns a 2003 Toyota Sequoia. The brake and vehicle skid control warning lights illuminated on the instrument control panel, and then the vehicle began to skid. The dealer repaired the vehicle; however, one year later the failure resurfaced. An authorized technician replaced the entire computer system at an expense of $2500. The failure mileage was 55,000 and the current mileage was 100,000. Update 12/14/09 updated 12/16/09

2003 Toyota Sequoia - has skid/traction control sensor failure (vsc trac) which effects the ABS - there's none now. We went through this November 2008 and paid extensively for the repair are reliving it again now. Toyota says this is common and will cost us $2K to fix. I am finding this problem with this model/year all over the internet. This is a Toyota problem and needs a recall - not a consumer only problem. Please help! we are afraid to drive our car on our trip to relatives at christmas. $2K eats up xmas budget! Toyota admits it's common - they need to recall the vehicles and fix this problem before someone gets killed! many reporting loss of control while driving and inability to brake.

I've owned a 2003 Toyota Sequoia since it was new, and have had several problems with the anti-lock brakes and stability control. The systems have failed repeated for the past three years, the warning lights are continuously on, and on two occasions the vehicle's anti-lock brakes have gone off while driving slowly ( and not braking ). the dealership where I purchased the vehicle says I need a new $2,000 computer for the brake control. The vehicle is faulty and unsafe, and Toyota needs to step up to the plate and fix this dangerous flaw in their anti-lock brake system.

Sept 09 - vcs & trac lights would come on randomly for last 6 months. Finally yesterday they failed completely. Lights came on, brakes starting vibrating, throttle control was impaired. Dealer recommended replacing vs computer. This is the second time vs system has had a problem. In 07 the dealer replaced the yaw sensor ass. When this happened vcs and trac lights came on, loss of braking and accelerating control. Fortunately when they failed speed was low there fore it was easy to come to a stop. I have requested old part returned to me.

Toyota Sequoia 2003 vsc lights on and off for entire duration of owning the vehicle...was "fixed" at authorized Toyota dealer early on in ownership and since will randomly go on and off. Most recently will be off with start of vehicle and with acceleration or turning will set of ABS light and beep, loose power and then the vsc lights will be on, when you let off of the accelerator. Some dealerships said to ignore the problem, don't feel safe when the most recent events cause the loss of power. I don't want to be going into traffic when this happens!

For the past year intermittently brake light on dash came on, if I turned off vehicle, restarted then the light stays off until the next time. Now with 80,000 miles on 2003 Sequoia vsc off, vsc trac & check engine lights came on going about 30 mpg. Took vehicle in for service found out there is a 'service bulletin' dating back to 2003 that Toyota is aware of computer failure concerning this issue. After researching on this website I've found over 200 complaints concerning this exact issue that has not been addressed by Toyota or any regulatory government Agency issuing a recall since this is a known issue that can cause loss of control of the vehicle. Why"? what is the wait? does a tragedy need to occur? how many more complaints need to be logged" I'm waiting for an appointment with the Toyota dealership to see if any 'good will' action will be taken since the reports I've read have indicated the repair/fix cost is between $1,600-$2,200 for the consumer which obviously should be covered by Toyota especially since this has been a known issue since 2003.

2003 Toyota Sequoia, the vehicle stability control suddenly quit working when in motion and tried to apply brakes and shuttered. It's in the shop now and they say it's an ABS skid control ECU that went out. Seems to be a common problem for this year model and a recall should be done.

Uncontrolled stopping of vehicle with out braking; driving on city roads car braked on its own to the point the car halted, and I had to quickly pull to the side of the road or be hit by cars behind me; happened 3 times within a 3 mile stretch while driving kids home from school.; skid control ECU was replaced, also faulty deceleration sensor, faulty steering angle sensor, old parts held by installer.

While under warranty, my 2003 Sequoia's electronic stability control system activated when accelerating around corners. The dealer replaced the vsc computer. Yesterday, August 13, while on vacation, the vsc, trac off, and ABS lights came on. The dealer stated that the vsc computer was not functional and would again have to be replaced. The cost is between 1500-2100 dollars. The dealer (West ashley Toyota, charleston, SC) stated if I did not replace it, it could activate and cause me to lose control. I asked if there was a fail safe and he did not know. I have not yet replaced the computer.

Vsc/traction control lights on. After turning the engine on, the vsc/traction control lights are off. After a few yards of driving, the lights turn on.

My ABS, vehicle skid control and trac control system has failed. Trouble codes indicate system failure and will require new ABS, trac and anti skid ECU. I have not had the repair done yet. I am concerned about the safety without these features. I am aware that there are several people having this same issue.

Stability control problems with an 2003 Toyota Sequoia. For several years the trac off, vsc trac and ABS lights have come off and on and are now on permanently rendering the stability control system useless.

Toyota Sequoia vsc trac lights on. Vehicle shudders when starting from a stop initially. Worried this could be a potential safety risk. Tundrasolutions.com has many other owners of 2003 Sequoia complaints about exact problem.

I own a 2003 Toyota Sequoia SR5 with 95000 miles. Vsc, trac, and ABS lights came on. Dealership said that the codes are faulty ECU. Cost of repair was $1700. The following week lights came back on. This time they tell me it is a faulty speed sensor on the front right. They recalibrated the vehicle and said if it comes back the cost of the repair is $400. Following week, the lights come on, same code for the speed sensor, so I have it replaced. Two days later, the lights are back on. Not certain what will code this time. After reading several posts online, it looks like this is a recurring issue with this vehicle. So, I'm filing a complaint sense there hasn't been a recall.

In 2005 bought 2003 Toyota Sequoia with 20,000miles in 2007 check engine light came on the dealer codes were C1223, C1247, C1203 had to replace computer assy. Replace translate control unit and reset readiness codes. This computer controls traction and loss of power. In 7/09 the "vsc trac" and "trac off" lights and ABS came on. I believe these are all safety issues that plague this Toyota model and recall is inorder. Are we going to wait for people to die before a recall is given?

The "vsc trac" and "trac off" lights both illuminated a week ago and remain on. The car will periodically decelerate and swerve slightly when I initially begin acceleration. I cannot accelerate during this time. I hear a grinding noise and beeping. The skid control light (the car with the skidmarks) lights up at this time. This happens daily, sometimes 2-3 times a day. I am afraid to pull out in heavy traffic, not knowing if my car will go or not! my heart always stops when this happens! I went to the dealership that day and was told that the diagnostics indicated that my brake booster and steering angle sensor needed to be replaced. I was told that the brake booster problem was a known problem and confirmed that after further research online. I was also told that another computer system usually fails when this system fails, but my car had not indicated a failure of that computer yet...so I am expecting that in the near future. We ordered a brake booster, gaskets, and a steering angle sensor, which will be installed when the parts arrive.

One day while driving the warning lights for the vsc off and traction control went on, along with the check engine light. At this point we realized that our ABS may have failed and our family was in danger. The brakes now lock and there is a grinding and swaying of the car. We'll be taking it in to be checked, obviously, but are concerned with the imminent safety issues along with the large number of similar complaints by other 2003 Sequoia owners.

Driving home and all of the sudden the vsc/trac/ and ABS light go on. Toyota says it is not dangerous but the manual says to take it in asap. Spent ~$1000 to replace the control unit.
