: the contact stated upon entering a highway at 60 mph, the vehicle accelerated rapidly. Brake pressure was applied, but the vehicle did not stop accelerating. Each time brake pressure was applied; there was a loud grinding noise. Although the cruise control was not engaged, the cruise control was manually activated in an attempt to stop the acceleration. With brake pressure applied, the contact managed to exit the freeway using the exit ramp. When the vehicle slowed, the park button option was pressed and the vehicle stopped. There was no further acceleration or grinding noise. The vehicle was towed to the dealer and is awaiting inspection of the problem. The consumer also stated, when she applied the brakes, the pedal became soft and went to the floor. Updated

When applying brakes in normal city street traffic at approximately 20 mph, brakes pulsed slowly several times and then failed. Brake pedal went to floor, car crashed into rear-end of car ahead.

Reported to Toyota on 2/7/04 file #200402110133. While driving on the highway, 70mph, cruise control on, both my wife and myself have accidentally bumped the gear shift knob with our hand and put the Prius into dynamic braking mode (dbm). The semi-truck behind me almost ran me over before I could get the car back into drive. Very dangerous!!! the brake light does not come on during dbm. Toyota should change the software to make a delay in the gear-shift for dbm similar to shifting into neutral?
