2009 TOYOTA PRIUS Complaints

I WAS DRIVING HOME FROM WORK IN MY 2009 PRIUS. WHEN COMING TO A TRAFFIC LIGHT (ICY CONDITIONS) I TOOK MY FOOT OFF OF THE ACCELERATOR, STARTED TO COAST AND THEN BEGAN TO BRAKE. I HAD TOTAL BRAKE FAILURE. THE CAR KEPT GOING AND I HEARD A THUMPING LIKE THE ANTI-LOCK BRAKES WERE TRYING TO ENGAGE. I FINALLY HAD TO THROW THE CAR INTO NEUTRAL. *TR

I HAVE A 2009 TOYOTA PRIUS. THE PROBLEM I DESCRIBE HAS BEEN HAPPENING SINCE I FIRST PURCHASED THE CAR, IT IS NOT A NEW PROBLEM. OCCASIONALLY, WHEN I STEP ON THE BRAKE TO SLOW DOWN WHEN APPROACHING A STOP SIGN, STOPPED CAR OR RED LIGHT, THE CAR DOES NOT STOP IMMEDIATELY IT SEEMS TO BE DELAYED IN IT'S RESPONSE AND THEN I HAVE TO STEP DOWN HARDER ON THE BREAK TO MAKE IT STOP AND THEN IT BECOMES A "HARD" STOP. THIS HAPPENS USUALLY AT SLOW SPEEDS. 20-55MPH. I'VE NOTICE THIS PROBLEM OCCURS MANY TIMES DURING THE WEEK, TODAY I ALREADY EXPERIENCED IT ONCE AND I AM BECOMING AFRAID TO DRIVE THIS CAR. I NEVER KNOW WHEN THE PROBLEM WILL OCCUR, THERE IS NO FOREWARNING. I HAVE BEEN CONCERNED FOR A LONG TIME AND FEAR THAT IT'S JUST A MATTER OF TIME BEFORE THIS BREAKING PROBLEM RESULTS IN AN ACCIDENT. I TOOK MY CAR IN YESTERDAY TO MY LOCAL TOYOTA DEALER AND THEY SAID EVERYTHING CHECKED OUT FINE AND THEY COULD NOT FIND/RECREATE THE PROBLEM. I HAVE MENTIONED IT TO THEM IN THE PAST AND THEY TOLD ME IT WAS JUST A DIFFERENT FEEL BECAUSE OF THE BRAKE "VACUUM" DESIGN. *TR

2009 PRIUS DISPLAYS ERRATIC BRAKING BEHAVIOR WHEN BRAKES ARE APPLIED ON IRREGULAR SURFACES...RR TRACKS, GRAVEL ETC. *TR

TL*THE CONTACT OWNS A 2009 TOYOTA PRIUS. THE CONTACT WAS POSITIONED IN THE VEHICLE WITHOUT THE ENGINE TURNED OFF WHEN THERE WAS FORCEFUL PRESSURE APPLIED TO THE ACCELERATOR PEDAL, FOLLOWED BY THE STICKING OF THE PEDAL; HOWEVER, THE ACCELERATOR PEDAL RELEASED WITHIN A FEW SECONDS. WHENEVER THE VEHICLE WAS IN OPERATION THE DRIVER APPLIED PARTIAL FORCE TO THE ACCELERATOR PEDAL TO AVOID THE PEDAL STICKING. THE AUTHORIZED DEALER WAS BEEN NOTIFIED OF THE MALFUNCTION. THE FAILURE MILEAGE WAS UNKNOWN.

2009 TOYOTA PRIUS. STRANGE BEHAVIOR OF ANTILOCK BRAKES/TRACTION CONTROL SYSTEM WHEN HITTING A SINGLE POTHOLE OR SMALL PATCH OF ICE ON OTHERWISE CLEAR ROAD SURFACE. VEHICLE SIGNIFICANTLY DAMPENS BRAKE RESPONSE AND DOES NOT RECOGNIZE THAT THE TIRES ARE NOW ON A GOOD CONTACT SURFACE AND CONTINUES TO BE IN TC MODE FOR EXCESSIVE TIME PERIOD. ONLY WAY TO ASSURE YOU WILL STOP WITHIN REASONABLE DISTANCE IS TO LIFT UP ON BRAKE PEDAL AND REDEPRESS (NOW OUT OF TC MODE CAR WILL STOP QUICKLY). THIS PROBLEM PRESENTS ITSELF REGULARLY WHEN ROAD CONDITIONS ARE RIGHT. THE PROBLEM IS THE MOST NOTICEABLE AT MODERATELY LOW SPEEDS I WOULD ESTIMATE 5-25 MPH BUT LIKELY OCCURS AT HIGHER SPEEDS WHICH IS LESS NOTICEABLE. IT SEEMS TO BE A FACTOR OF DISTANCE OR THE FACT THAT THE CAR DOES NOT REALIZE THE WHEEL IS GETTING TRACTION AGAIN. *TR

THE UNINTENDED SPEEDING ALSO HAPPENS ON 2009 TOYOTA PRIUS WHEN DRIVING ON A BUMPY ROAD, THIS HAPPENS EVERY TIME WHEN I HIT A POT HOLE ON ONE TIRE, CAR PULLS TO THE OPPOSITE SIDE AT AN INCREASED SPEED AND BRAKE SEEMS TOO SLOW TO REACT. *TR

I HAVE A 2009 PRIUS, PURCHASED IN MARCH 2009. SEVERAL TIMES MY BRAKES HAVE STOPPED WORKING ON ROUGH SURFACES AND THE SURGED FORWARD. EACH TIME I WAS ATTEMPTING TO STOP FOR A TRAFFIC LIGHT. I WOULD BRAKE, THE BRAKES WOULD WORK, AND THEN I WOULD HIT A ROUGH PATCH IN THE ROAD, THE BRAKES WOULD STOP WORKING, AND THE CAR WOULD SURGE FORWARD. THE MOST RECENT INCIDENT WAS IN JANUARY OF THIS YEAR. EACH TIME I WAS ABLE TO STOP THE CAR BY LETTING UP ON THE BRAKES AND THEN BRAKING AGAIN. LUCKILY I HAVE NEVER HAD A CAR IN FRONT OF ME WHEN THIS HAPPENED. ONE TIME THOUGH I ALMOST WENT INTO THE INTERSECTION BEFORE BEING ABLE TO STOP. *TR

I OWN A 2009 TOYOTA PRIUS AND I HAVE EXPERIENCED THE SAME ISSUE AS THE REPORTED 2010 BRAKES. WHEN I DRIVE OVER POT HOLES OR STREET COVERS, MY VEHICLE FEELS LIKE IT'S OUT OF CONTROL. WHAT IS THE DIFFERENCE BETWEEN THE BRAKING SYSTEM IN THE 2010 WITH THE 2009 MODELS? *TR

TL*THE CONTACT OWNS A 2009 TOYOTA PRIUS. WHILE DRIVING APPROXIMATELY 20 MPH AND ENGAGING THE BRAKE PEDAL AND MAKING CONTACT WITH A POTHOLE THE VEHICLE WOULD ACCELERATE. THE DEALER HAS NOT DIAGNOSED THE FAILURE AND IT CONTINUES TO OCCUR. THE FAILURE MILEAGE WAS 16,000.

2009 TOYOTA PRIUS - DELAYED BRAKING HAS BEEN EXPERIENCED SEVERAL TIMES. SEEMS TO BE RELATED TO HARD BRAKING. IT ONLY LAST ABOUT A SECOND BUT IS VERY UNLIKE ANY OTHER CAR I HAVE DRIVEN. I HAD PASSED IT OFF AS JUST SOMETHING WEIRD BUT THEN I HEARD OTHERS DESCRIBE IT ON THE TV AND I SAID THAT HAPPENED TO ME TOO!" AS A SAFETY ENGINEER IN THE AEROSPACE INDUSTRY, IT DOES SEEM TO BE RELATED TO THE DELAY FROM SWITCHING FROM REGULAR BRAKING TO HYDRAULIC BRAKING...SOMETIMES IT SEEMS TO SWITCH IN A WEIRD WAY. *JB
