| Description of the problem | Purchased 2004 sienna xle awd limited 2/18/15. While commuting to work the traction control system randomly activates in dry conditions (usually on downhill angled turn) causing loss of power, activation of front right brakes, and the steering wheel jerked from my hands (resulting in transient overall loss of control of vehicle). This defect has occurred 6 times in 2 days and i am currently afraid to drive the car, especially with a 3 month old. There have been multiple reports on edmunds. Com and other toyota forums that support this is an ongoing problem with this model/year vehicle. This is a safety defect and the vehicle should be recalled to prevent injury or fatality and to resolve the issue with the tcs. There is no way to turn off the tcs manually and this issue can cause an accident. |
