2004 Toyota Prius transmission problems

2nd occurrence of toyota prius acceleration. While wife leaving daughters school, car accelerated (pedal off the accelerator!), she jammed on brakes, but was close in provoking an accident on main street. This is the second occurrence. First time, she hit a taxi while stopped in a red light. Accident was reported by police (no injuries). First time took car into the dealer (no apparent problems). Planning on taking car again to dealer tomorrow.!

I have a 2004 prius. The shift lever began to stick in the select gear position instead of going back to the neutral position. When this happened, the park button would not work, causing the car to move forward if the brake was released. I called toyota and complained twice. The gear select lever needs to be modified so it doesn't stick and the software changed to allow the park function to work when the car is stopped regardless of the position of the gear select lever.
