2014 TOYOTA PRIUS C Power Train Problems

Brake failure / Unintended Acceleration / Unknown cause Driving at approx 25mph on urban street (road in good condition no potholes, ramps, etc) I began to slowly brake as I approached a red traffic light. Instead of braking, the car began to accelerate quickly. I pressed the brake pedal again - no response. Pressed down hard for a third time which executed an emergency stop. This all happened within 1 or 2 secs. There were no injuries or involvement of other cars on this occasion. However, had I been any closer to the car in front, I believe I would have rear-ended it. Had this occurred a few moments later, at the busy junction 400m ahead, it could have been fatal. I am absolutely sure it was not driver error.

CITY STREET ...PRESSED ON GAS AFTER THE LIGHT CHANGED AND IT DID NOT GO FORWARD AND THEN WAIVERED FOR AWHILE. I WAS VERY CLOSE TO HOME. I DO NOT KNOW HOW IT WILL WORK TOMORROW . NO WARNING LIGHTS WERE ON. IT HAS ACTED FUNNY BEFORE LIKE THIS ON HIGHWAY TRIPS AND THEN IT WOULDN'T DO IT. TOYOTA DEALERS DO NOT EVEN KNOW ABOUT THEM AND IT IS ANNOYING. IT FEELS LIKE A TRANSMISSION SLIPPING BUT HAS LESS THAN 70,000 MILES. I THOUGHT MAYBE HEAT IS DOING IT BUT NOW THAT IT IS OUT OF WARRANTY IE OVER 5 YEARS OLD, I DO NOT KNOW WHAT TO DO. I AM UNSURE WHAT CAUSES THIS SINCE NO LIGHTS WARN ANYTHING IS WRONG.
