Purchased my 2012 Prius about a week ago. Love it. When I got the vehicle the EV mode was functioning properly. After a couple of days I left a vehicle at the dealership so they can install illuminated door seals, lower moulding and heated leather seats. Picked it up after two days and now, when I press EV mode it runs till 10 MPH and then turn off with "excessive speed" message. Tried with wormed-up vehicle, on leveled road, with no excessive acceleration, several times and always the same result - "turning Ev off due to excessive speed". Any ideas??? Thanks a lot.
