2010 Toyota Prius service brakes, electric problems

“EVER SINCE I PURCHASED MY 2010 PRIUS IN NOVEMBER, 2009 THE BRAKES HAVE BEEN A PROBLEM. WHEN BRAKING WHILE DRIVING OVER A BUMP OR POTHOLE THE CAR LOOSES BRAKING ABILITY AND THERE IS A SURGE OF POWER. THE DEALERSHIP CLAIMS THERE IS NO PROBLEM AND THE RECALL WORK HAS NOT MADE A NOTICEABLE DIFFERENCE. *TT”

“HAVING PROBLEMS WITH THE BRAKING ON MY 2010 TOYOTA PRIUS. AT SLOW TO MODERATE SPEEDS WHILE I AM BRAKING AND GO OVER A POTHOLE THE CAR SEEMS TO STOP BRAKING AND KEEPS GOING. I THEN HAVE TO DEPRESS THE BRAKE HARDER TO MAKE THE CAR STOP. I HAVEN'T HAD ANY COLLISIONS BECAUSE OF THIS ISSUE BECAUSE I HAVE NOT BEEN FOLLOWING CLOSELY BEHIND A CAR. BUT I BELIEVE IF I WAS, I WOULD HAVE DEFINITELY REAR-ENDED ANOTHER VEHICLE. *TR”

“I PURCHASED A 2010 PRIUS. WITHIN A 100 MILES, THE BRAKE PEDAL RANDOMLY LOCKED UP, THE BRAKES GRABBED AND BROUGHT MY CAR TO AN ABRUPT HALT. THE BRAKE PEDAL REMAINED LOCKED FOR ABOUT 3-5 SECONDS. THE CAR WOULD NOT MOVE FORWARD OR BACKWARD UNTIL AFTER THE BRAKE PEDAL UNLOCKED ITSELF. INITIALLY THIS HAPPENED IN REVERSE MODE SEVERAL TIMES, THEN IT WAS HAPPENING ONCE A WEEK AND IN FORWARD MODE AS WELL AS REVERSE. I TOOK IT IN FOR REPAIRS, MOST RECENTLY TOYOTA HAD MY CAR FOR A MONTH. NOTE THAT DURING THIS MONTH LONG INVESTIGATION NOTHING WAS DONE TO MY CAR, IT JUST SAT THERE. UPON MY LEAVING THE DEALERSHIP THE BRAKE PEDAL ACTUALLY LOCK UP! THE FIELD REPRESENTATIVE CONFIRMED THE PEDAL TO BE LOCKED AND WOULD NOT RELEASE FOR 30 SECONDS OR LONGER. HE TOOK MEASUREMENTS AND THE ENGINEER TOOK PHOTOS OF THE BRAKE PEDAL AS IT WAS UP IN THE AIR AND NOT DEPRESSED AS A NORMAL PEDAL WOULD BE. HE INSTRUCTED THE SERVICE MANAGER TO SEND ME HOME IN A LOANER CAR AND NOT THE PRIUS BECAUSE OF THE BRAKE PEDAL. I WAS SO RELIEVED THAT SOMEONE FINALLY SAW THE BRAKE PEDAL LOCKED UP AND NOT RELEASE. AFTER AN ADDITIONAL WEEK, THE DEALER CONTACTED ME AND SAID THAT TOYOTA DETERMINED THAT THIS…”

“BACKED 2010 PRIUS UP AND STARTED TO MAKE U-TURN IN DRIVEWAY. WHEN PULLED FORWARD TURNING APPLIED BRAKES AND WELL THERE WERE NONE. TRAVELED ABOUT 15 FEET AND HIT A BRICK WALL. AFTER SOME DELAY THE ENGINE NOW HAD SOME CONTROL AS THE BRAKES ALSO DID. WAITING FOR TOWING INSTRUCTIONS TO GET THE CAR TO GARAGE. MAXIMUM SPEED WAS MAYBE 5MPH. *TR”

“I HAVE A 2010 PRIUS, AND WHEN I APPLY THE BRAKES AT ANY INTENSITY AND MY VEHICLE HITS A DEFECT IN THE ROAD SURFACE, THE ABS SYSTEM SEEMS TO RELEASE BRAKE PRESSURE TO ALL 4 WHEELS COMPLETELY FOR ABOUT HALF A SECOND. THIS MAKES ME QUESTION THE EFFECTIVENESS OF THE BRAKES IN AN EMERGENCY SITUATION, ESPECIALLY ON HOUSTON'S NOTORIOUSLY NEGLECTED ROADWAYS. I WAS TOLD THAT THIS WAS NORMAL BY BOTH TOYOTA MOTOR CO. AT 1-800-331-4331 AND ALSO BY THE DEALER. TMC INFORMED ME THAT THIS IS THE WAY THAT THE ABS SYSTEM WAS DESIGNED. PLEASE LAUNCH AN INQUISITION AND/OR INVESTIGATION INTO THIS MATTER, FOR THE SAFETY OF THE OWNERS OF ALL TOYOTA PRIUS VEHICLES. *TR”

“MY 2010 PRIUS' BRAKES DID NOT RESPOND WHILE ON THE ROAD ON 1/22/11. THEN 2X AGAIN ON 1/23/11. AS A CONSUMER, I DO NOT KNOW WHO REGULATES CAR COMPANIES BUT I HAVE CALLED THE MANUFACTURER AND THEY NEED TO 'DUPLICATE' THE PROBLEM. IN THE PAST, MY BRAKES WOULD ACCELERATE BEFORE IT WOULD CATCH AND THE PROBLEM WAS NOT 'DUPLICATED' BY THE DEALER. THIS TIME THE BRAKES FAILED ME 3X WITHIN 24 HOURS AND I AM EXTREMELY CONCERNED. I WOULD LIKE TO KNOW WHICH GOVERNMENT AGENCY TO REPORT IT TO AND WHAT BETTER OPTIONS I HAVE TO GET A RESOLUTION. *TR”
