| Description of the problem | Attempted to accelerate to pass a large truck and vehicle started accelerating out of control. Tried to brake and that didn't work. Applied foot brake and that didn't work. Speed may have increased to approx 70-80 mph. Speedometer show approx 45 mph. Unable to steer vehicle. It was as if the motor had stopped and i had no power steering. After hitting 2-3 vehicles and then the right lane bridge wall the front tire and steering assembly bent inward nd that caused the van to stop. That god that noone was injured but something is seriously wrong. I've seen several complaints of sudden acceleration in sienna vans and this need much attention. |
