My vsc off and vsc trac lights popped on simultaneously with my check engine light, while traveling on straight, paved highway at about 55 MPH, for no apparent reason. I was not braking when all lights suddenly appeared. I was cruising comfortably at highway speeds on straight, flat, paved road. I have read countless other complaints filed by other toyota owners with the exact problem. My mechanic explained this can be very hazardous as this system cannot be disabled. So, these lights may pop on and off, and the vsc system may spontaneously engage without my knowledge or control, and this can greatly affect acceleration and cause accidents. I haven't done anything operationally to cause these lights to come on and I feel toyota should accept responsibility for this defect which could have very strong safety implications.

A few months after we purchased the vehicle in december 2004 we noticed that the traction lights are coming on periodically. We took the car to toyota service to check the issue and been charged hundreds of dollars for diagnosis and sensor replacement. However the problem was not solved and even got worst: the traction and brake lights were continuously on now. In 2010 we received a notice about a recall with regard to the above issue and brought the car to toyota dealership located at 4248 morse rd., columbus, oh 43230. The car was serviced but a few hours afterwards all the lights were on again. When we returned to the same dealership with the same complaint we were told that the recall was on the vehicle computer adjustment, which was done, and that and any additional services will be charged in full. We looked up the recall document and realized that it is clearly specified under remedy that: if the reflash cannot be completed on a particular vehicle, the ecu will be replaced with a new one. This service will be performed free of charge. Since the manufacturer dealership is refusing to comply with the recall requirements we would like to bring the issue to your attention and seek your intervention.

While driving along at city street speeds, during dry weather, on paved roads, my vsc trac and trac off lights come on. No other warning lights come on. Then a buzzer sounds for about 3 seconds. Then at the same time, a strange grinding sound comes from underneath the car, and the brakes seem to start working for no reason. I quickly pull over, turn off the car. I check the outside of the car and see no indication of running over anything. I then start the car and all the lights are back to normal (off). This happens about 2-3 times a month, for about a month or 2 now. I have not been able to determine any problems.

Vsc/trac and engine light came on. Dealer said problem was o2 sensor. They replaced 02 sensor and all lights cleared. After one week the vsc0/trac lights came back on and they go on and off every time we drive the truck. Dealer said we need to replace skid control ecu. We decided not to replace the unit because of 1800.00 cost.

When shifting the transmission in to drive all the lights work effectively, but the light that indicates the vehicle is in the d position (drive) burns out. This is a safety problem that may cause an accident. This is a common problem that the dealer is aware of as a consistent defect.
