I WAS DRIVING MY 2010 TOYOTA PRIUS ON A SNOW COVERED, ROUGH RESIDENTIAL STREET. WHILE TURNING INTO A DRIVEWAY TO TURN AROUND TO GRAB A PARKING SPOT, I APPLIED THE BRAKES AND THEY COMPLETELY RELEASED AND I SLAMMED TO THE SNOW PILED AT THE ENTRANCE TO THE DRIVEWAY. THE FRONT BUMPER COVER GOT A HOLE PUNCHED INTO IT THE SIZE OF A BASEBALL FROM THE FROZEN SNOW. SINCE THEN THE BRAKES HAVE RELEASED WITHOUT INCIDENT BUT NOT WITHOUT CONCERN. I CALLED AND REPORTED THE PROBLEM TO MY TOYOTA DEALER AND HE ASKED "DO I HAVE AN ERROR SHOWING UP ON THE DASH SCREEN" AND I SAID "NO". I ASKED WAS THERE A NEW UPDATED PROGRAM AND HE SAID HE DID NOT KNOW ANYTHING ABOUT IT AND THEY DON'T HAVE A FIX ANYWAY. THIS WAS BEFORE THE CAR WAS RECALLED BY A COUPLE OF WEEKS BUT AFTER TOYOTA HAD STARTED LOADING A DIFFERENT PROGRAM ONTO THE CAR. ON FEB. 17, 2010 TOYOTA DID FLASH THE CAR'S COMPUTER TO FIX THE PROGRAM ISSUES. I WOULD LIKE TOYOTA TO HAVE THE FRONT BUMPER COVER REPAIRED. THANKS. *TR

I OWN A 2010 TOYOTA PRIUS. I HAVE EXPERIENCED SOME DANGEROUS OCCURRENCES WHILE DRIVING. 1) OCCASIONAL LOSS OF TRACTION (FOR A SECOND+-). PROBLEM HAS OCCURRED AUG, 2009 - PRESENT. USUALLY OCCURS WHEN HEADING DOWNHILL OR WHEN DRIVING OVER A MANHOLE OR DRAINAGE COVER. CAR FEELS AS IF SLIPPING OR AIRBORNE FOR A MOMENT.. 2) FREQUENTLY IMMEDIATELY AFTER STARTING CAR, AT SLOW SPEEDS OF ONLY 0-5 MPH, CAR IS JERKY EACH TIME BRAKE IS APPLIED. PROBLEM HAS OCCURRED AUG, 2009 - PRESENT. PASSENGERS ARE ACTUALLY JERKED, AS IF DRIVER WAS APPLYING BRAKES TOO SUDDENLY. EVEN WITH GREAT ATTEMPT TO STOP SMOOTHLY AND GRADUALLY, IT IS IMPOSSIBLE. BRAKES GRAB AND JERK. THIS OCCURS BOTH IN REVERSE AND FORWARD, YET NOT EVERY TIME ENGINE IS STARTED. IT LASTS FOR ONLY A MINUTE OR SO, BUT MAKES MANEUVERING WHILE PARKING OR ENTERING TRAFFIC UNSAFE, AS WELL AS MAKING DRIVER LOOK INEPT. I CANNOT FIGURE OUT IF THIS IS A BRAKING OR ACCELERATION PROBLEM. WHEN CALLING A TOYOTA DEALER (NOV, 2009), I WAS TOLD THEY HAD NO SIMILAR REPORTS OF THESE PROBLEMS AND OFFERED NO SOLUTION. MY CONCERN HAS INCREASED WITH THE RECENT RECALLS WHEN CALLING A TOYOTA DEALER PREVIOUSLY, I WAS TOLD THEY HAD NO SIMILAR REPORTS OF THESE PROBLEMS.

The subject vehicles are the first model year of a new design generation of the Prius model line.The vehicles are powered by a hybrid drive system that uses both a regenerative braking system, which converts vehicle momentum into electrical energy to be stored in onboard batteries, and a hydraulic brake system more typical of the brake system used on non-hybrid vehicles.As is the case for other similarly designed hybrid vehicles the interaction and management of the two braking systems during ABS braking is complex and requires a sophisticated control system.In a February 9, 2010 Defect Information Report, Toyota advised the agency of its plans to conduct a safety recall to address inconsistent brake feel and increased stopping distances that may occur during braking events requiring ABS operation, such as would occur when braking on rough or low friction road surfaces.Toyota will reprogram the ABS control unit with improved software that addresses this condition.Based on Toyota's action the investigation is closed. ODI will continue to monitor the subject vehicles' performance and will take further action as future circumstances dictate.
