2 Vehicle Speed Control problem

Failure Date: 01/10/2010

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. Continuing through the gate I was able to reach a large open area whereupon I turned the steering wheel as hard as I could to make sure the vehicle would only circle. After a bit of time the engine roared pickup speed then stopped. This same surge occurred on several occasions but I thought I did something to cause this problem.

3 Vehicle Speed Control problem

Failure Date: 05/01/2009

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 while it was doing the revving without touching the gas pedal, they finally repaired the value . I wrote to Toyotas and told them and they said it was not of there concern, idiots knew there is a problem and would not fix it, but 800 dollars later they did and not under the warranty. Those people need to be held accountable for hiding all the concerns, I want me repair money back and plan on causing enough crap with the news media until I do.

Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6) 2003 Toyota Sienna my vehicle was accelerating from a ramp onto the highway when I discovered to my horror that even after I took my foot off the gas pedal (about 60 mph), the vehicle continued to accelerate (up to 90 mph). I even tried using my foot to hook the gas pedal toward me to stop the car. When that did not succeed, I pressed on the parking and normal brakes to slow down the car and turned off the car. The very next day, I had my car towed to , diehl Toyota of york [xxx] . They did not discover any issues. However in light of the massive Toyota recalls, I believe that my car is similarly defective. I had tried calling 800 331 4331, the phone number provided by Toyota for such defective vehicle issues but no one ever picks up.
