The contact owns a 2014 Toyota Prius V. while driving approximately 20 mph and approaching a stop, the brake pedal pressure released when the pedal was depressed. The vehicle surged forward. The contact had to release and reapply the brakes in order to stop the vehicle. The failure occurred at least twelve other times. The vehicle was taken to the dealer, but they could not duplicate the failure. The manufacturer was not notified of the failure. The vehicle was not repaired. The approximate failure mileage was 27,000. The consumer stated the failure moreso relates to a braking failure rather than sudden unintended acceleration. The "surge" that was felt was releasing of the brakes and an abrupt halting of the driver's commanded deceleration. The brake pedal had to be depressed to the floor or released entirely and depressed again.

I experienced sudden but momentary braking when traveling at high speed (> 50 mph) while either entering ro exiting hwy. This occurred twice in last two mons. I drove my car to closest dealership the 2nd time this happened (Nov. 21, 2105; waldorf md Toyota), who told me they received an email (but no recall) from Toyota corporate about this issue. Dealership could not detect the problem or reproduce it so, as instructed by dealership, I called Toyota corporate Nov. 23, 2015 to get case number assigned. At one point, Toyota representative demanded "what do you want from Toyota?" case was 'escalated' but no case worker was assigned until Nov. 30, 2015. Toyota corporate stated that the technician had to reproduce the problem and if they cannot, there was no problem and dealership would return my car to me without repair. The dealership protested and said they ot required to reproduce the problem as it was an episodic and rare event. Further, they would not return my car to me until the problem was fixed because it was a safety issue. Waldorf Toyota still has my car (over two weeks now as today is Dec. 9, 2015). They have not received any further guidance but are waiting for the field technical specialist to examine the car. I finally received a call from customer relations at the regional office (central atlantic Toyota) to authorize access to the edr (electronic data recorder). This means over two weeks have passed before even the first step was taken by Toyota to diagnose the problem.

We were in stop and go traffic on the highway for just over a half hour with my two young children in the car. Speeds below 10 miles per hour. At the time of incident, we were traveling between 5-7 mph. Tried coming to a stop with about 10 feet between our car and a big rig in front. The brakes wouldn't egange. Repeatedly stomped on the brake pedal between 5 to 10 times. Car break would not engage and we rolled into big rig bumper. This gave us a chance to power down the car with the push/start button.
