| Description of the problem | Driving my 2004 toyota sienna 65mph on the highway on dry pavement the vsc light went on, a buzzer sounded, and i was unable to steer or brake the vehicle. The steering wheel started moving rapidly right and left causing the car to fishtail and the brake pedal went going in and out on its own. Everything went back to normal after about 20 seconds or so, and i pulled off into the breakdown lane. I then pulled out again slowly to get my car in a safer area and it happened again. This time i was going much slower but it was horrifying none the less. I then pulled off the road and had the car towed to the toyota dealer. I found that a technical service bulletin had been issued on my car in 2005 and that the steering angle sensor was the culprit. The bulletin says that "some customers may experience an intermittent vsc activation." owners of the 2004 sienna have not been notified of this problem, which after experiencing is clearly a safety issue, and there should have been a recall rather than a tsb. The tsb seems cleverly worded to avoid the fact that a driver could loose all control of the steering wheel and brakes which is clearly a safety issue. |
