Filed Jul 11, 2023 · Steering, Suspension · SD

The slip indicator light and alarm comes on sporadically, engaging the ABS suddenly and unexpectedly, when we are on completely dry roads. Happens while driving 40-80 mph. And doesn’t matter if I’m going straight or turning.

- Traction control engaged at high speed(70 mph on interstate) causing the vehicle to brake abruptly and pull the vehicle to the right. Had I been traveling in the left hand lane, I could have been forced into the right hand lane causing a collusion with another vehicle. Also occurred at lower speed(30 mph on a windy road) causing the same issue as described above, almost causing the vehicle to leave the paved surface. - Mechanic was able to duplicate the issue - Mechanic diagnosed intermittent traction control activation, scanned computer for codes. Yaw rate/steering angle correlation causing false activation ABS/traction. Replaced hub bearing and spindle. Four wheel alignment, including check castor, camber and adjust toe. Performed zero point calibration and reset ABS memory. - Traction control lights up briefly

The failing component is the VSC/ABS system. It puts the occupants of the van and other motorists at risk of either causing a collision or causing the driver of vehicle in question to be unable to control the vehicle . The failure appears when going in a curve in the road at low speed causing the abs to engage lock the brakes and steering wheel rapidly decelerating the car and causing the car to jerk to one side or the other and go into a skid where the driver is unable to control the wheel due to steering wheel locking up when it happens the VSC and TRAC lights come on and there is a loud and rapid beeping that can be heard inside the vehicle. The issue usually appear when going between 25-40mph in banking curves

Abs some times activates when driving a light curve road at speed around 30-40 MPH. Usually a steering wheel is about 2 or 10 o'clock positions. At the time vsc indicator flashes and warning alarm goes off. This causes a sudden breaking and it becomes very difficult to control the car.

In motion, on dry, off-camber highway curves, with slight acceleration, the ABS/vsc /trak engages, briefly jerking the steering to one side. Dash warnings: "vsc" "trak off" + "check engine". Reducing mechanical "slop" (wheel bearings, steering rack & pinion, etc.) tends to reduce frequency of occurrence. Toyota dealer diagnosis: "steering control system fault". >"toyota knows about -- but, does not know how to fix this problem."< dealer-suggested workaround: "pull fuzes to disable vsc and ABS systems..." dealer repair documents are with previous owner...

We bought this car about 1 1/2 years ago. After having it for a bit we learned of the problem. You will be driving down the road (dry, sunny day) and all of a sudden the car will start beeping, the traction control will kick in and start pressure braking the car. The car thinks it pulling you out of a skid, so you have to strongly hold the steering wheel. It's terrifying! I feel like the car is going to pull me off the road. I won't drive the car in rain because of this and honestly don't feel comfortable even driving it most the time. You never know when it is going to happen and it typically happens while you are driving high speeds on the highway. This is a known problem with toyota - they have a technical service bulletin br008-04 (ABS& traction control intermediate vsc system), which shows they have replaced the defective part. However since the car is old, they won't replace it anymore. It is the companies defect part! How many people have gotten into accidents and/ or died from this? And just to say it - the 2004 version doesn't have a way to manually just turn off the traction control. We have tried everything! I took it to a toyota dealership and they agreed this is what is wrong with the car, but said they won't fix it for free - they wanted $800. I contacted toyota customer and they basically told me they don't care if people die from this, because the car is old and they don't have any responsibility after a certain age of the car. We have 3 kids and this is not an acceptable answer! My whole family has toyota vehicles and if they don't make things like this right, we will not be anymore! The car is new to us and is frankly unsafe. This is toyota's faulty part. I have seen several message boards with the same issue. How can a deadly issue expire?

When driving under normal conditions the vehicles' vsc will engage. The dashboard lights go off, there is a loud interior beeping sound, the ABS engages, the car slows down drastically at once. The roads are dry. At first this happened while driving normal speed exiting or entering an hwy off/on ramp. Then happened yesterday as I was driving on neighborhood streets at about 25-30 MPH. I could hear a rubbing on the back tires as if the brakes were on.

Vsc light turned on after front wheel alignment, two dealers cannot make it go off. It appears that stabilization was not working for some time. Light only appeared after alignment procedure. Electronics are part of a $2700 ABS module. Abs works. No indication of the lack of vsc is a safety issue. Others have seen this problem. Apparently toyota redesigned the system for the next year's model.

While driving 55 MPH on a straight stretch of road, the car careened to the right and the automatic braking system suddenly became engaged and our car was forced to stop on the side of the road. After turning off the car and restarting, the problem appeared to be a singular incident. However, about one year later, on march 27th, 2015 a similar occurrence happened but at only 25 MPH. The car, however, was not drivable. After driving about 25 feet, the traction light came on, the signal sounded and the car brakes began to pump as though the car was skidding. As the car slowed almost to a stop, stepping on the brake manually stopped the signal and the light , as well as, the ABS system temporarily allowing the car had driven a short distance. After another 25 feet, the traction light went on again, the warning bell went off and the ABS system was activated again. This continued for a significant distance before I determined that the car could not be driven without a significant accident occurring. Unfortunately in the first incident, we were almost struck from behind by a closely following vehicle. In the second case, the same nearly occurred as I tried to exit onto a roadway.
