2009 Toyota Sienna acceleration complaints

Filed Jan 28, 2010 · Acceleration · 5,000 miles · FL

In april 2009 the accelerator stuck on my 2009 toyota sienna van. The dealer failed to replicate the problem and neither the dealer nor toyota has made any progress to resolving. Now I see where a vast number of other toyota vehicles are similarly plagued and my confidence in the sienna is further eroded. Please help! Tw*

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.

On an early saturday april 18, 2009 trip to the airport the cruise control stuck while accelerating and would not disengage by pressing the brake pedal or by pulling the cruise control lever (located on the steering column) towards the driver. I had just gone through an automatic tollgate in the far left lane and began accelerating (and probably hit the 'resume' feature of the cruise control lever) in order to get immediately over to the far right lane to exit. Within seconds I was up to an adequate speed and touched the brake. The car continued accelerating. I pressed the brake more firmly and pulled the cruise control lever towards me. Neither action disengaged the cruise control. I was able to avoid traffic and point the car towards the right shoulder. I then pushed the gear shift into neutral and the car engine slowed down, the car stopped accelerating, and the cruise control disengaged. On my return trip I tried to duplicate the actions which preceded the problem but was not successful. (I have driven the car about 5600 miles and this was the first time this problem has occurred.) the same day I took the car to a large toyota dealer. They drove the car several miles and did not have the problem occur. So they were not able to find a problem. They said they could only fix a problem if they could experience it. And, they suggested I take the car to the toyota dealer that sold it to me. Later the same day I did return the car to the toyota dealer that sold it to me. They were good listeners and kept the car for several days of driving, diagnostics, and phone calls to toyota. But, in the end they too, could not locate a problem and returned the car to me unchanged. My confidence in this vehicle is greatly diminished. While I was successful in disengaging the accelerating cruise control by putting the car into neutral I do not want to have to depend on that especially in a heavy traffic situation.
