The contact owns a 2009 Toyota Prius. The contact was positioned in the vehicle without the engine turned off when there was forceful pressure applied to the accelerator pedal, followed by the sticking of the pedal; however, the accelerator pedal released within a few seconds. Whenever the vehicle was in operation the driver applied partial force to the accelerator pedal to avoid the pedal sticking. The authorized dealer was been notified of the malfunction. The failure mileage was unknown.
