RESPONSE<\/p>\n

I consider this as a severe safety issue. Sounds like your accelerator is sticking. This may be from a faulty accelerator pedal sensor. Testing will require a capable scan tool<\/a>. You may need to take this to a Toyota dealer because not every local shop will have one for a Prius.<\/p>\n
