“I turns my Toyota Sienna into a driveway of a storage facility and placed the vehicle into park while trafficpassed by as this road was also the exit road from costco. When it was safe from other vehicles and is was safe to back out of the driveway I took the vehicle out of park and suddenly the vehicle lurched forward ramming into an iron gate bending it wide open. The vehicle continued through the gate even though I turned off the ignition , jammed my brakes an tried to place it into park all to no avail. …”
NHTSA complaint #10317294, filed 2010-03, 14,000 miles“I have owned a 2003 Toyota Sienna since new. I had a extended 100k warranty on this vehicle. At 80,000 miles a check engine light came on, it was replaced, at 82,000 miles it came on again and was replaced., then at 94,000 miles the car started stalling and would not crank for several minutes, the dealer told me that it was in my head, nothing was wrong, it continued to do this more often, at 94,400 I told it back and the idiots told me the same thing, I fought with this condition until it final effected the accelerator, the car revved up wide open and continued until I got it to the dealer…”
NHTSA complaint #10314733, filed 2010-02, 94,000 miles“Unintended high speed acceleration I was accelerating to merge onto the highway and I briefly used the brakes to allow a large truck to go past before merging. I'm not sure if I then put my foot on the accelerator or the brake, but the 2003 Toyota Sienna began acceleration on its own as though the cruise control had been set at 100 MPH and it was trying to get there! I did not have the cruise control on at the time. I then put on the brakes to reduce my speed, and I was able to reduce the speed but the brakes were definitely fighting against the vehicle's desire to go 100 MPH. …”
NHTSA complaint #10243306, filed 2008-09, 67,000 miles“The Toyota Sienna's gas pedal has been and remains intermittently sticky. It takes some foot stomping to depress the gas pedal in order to accelerate the vehicle. Toyota does not believe this to be a major problem when I questioned them a few years ago.”
