My daughter owns a 2005 Prius. She was driving along the highway and the accelerator pedal stuck at about 40 mph. Try as she could, she could not get it loose. Somehow, she finally succeeded, whether by shifting I do not know. Question: Has this happened to you? What did you do? It sounds dangerous to me to shift, but what else? The dealer is still trying to figure it out- has never known it to happen before.
