| Description of the problem | Sudden deceleration of vehicle: 2004 toyota sienna xle. The vsc engages, without warning, on smooth, dry roads and when cornering or negotiating a curve. We are the original owners and have never experienced this until the first incident in late oct. 2014. We did not take any action because although road conditions good, we were rounding a sharp bend in the road and assumed this had something to do with the incident. Vehicle speed was approximately 25 mph as the vehicle suddenly decelerated, the vsc light came on and a rapid beeping alarm sounded. The vehicle pulled to one side and steering the vehicle became extremely difficult. The whole incident, start to finish, lasted approximately 5 seconds. The next incident happened in early december 2014. Again, all the above described things happened, except vehicle speed was approximately 35 mph going around a gentle curve in the road. I did some research and found many complaints concerning this issue but do not see any recommendations or recalls officially issued by toyota. It appears most of the dealer recommended repairs did not correct the problem. Today (december 26, 2014), this same issue happened five times within 40 minutes. My wife managed to get the vehicle home and we called our local toyota dealer, described the issue and they informed us they have never received any complaints concerning rapid deceleration of this model year, before our phone call. I've scheduled an appointment for december 30, 2014 to have the vehicle checked out and have recall work done concerning the "shift lock solenoid assembly". Will update after appointment. |
