2009 Toyota Prius service brakes, electric problems

“GOING OVER POT HOLES IT FEELS LIKE THE BRAKES SKIP. IT OCCURS ALMOST EVERY TIME I GO OVER A HOLE OF SOME SORT AND APPLY THE BRAKE. I ASKED TOYOTA TO DOUBLE CHECK THAT THE ABS BRAKES WERE WORKING CORRECTLY. TOYOTA SAYS ITS NORMAL AND THAT THE ABS SYSTEM WORKS BY MOMENTARILY INTERRUPTING THE BRAKING FORCE TO PREVENT A SKIT AND THE RESULTING LOSS OF CONTROL. *TR”

“I OWN AND DRIVE A 2009 TOYOTA PRIUS, AND I HAVE NOTICED A LAPSE IN BRAKING WHILE BRAKING ON ROUGH ROADS. THIS GOES BACK TO DEC. 2009, SHORTLY AFTER I PURCHASED THE VEHICLE. ON MY CURRENT COMMUTE, I'M NOTICING THIS LAPSE IN BRAKING ALMOST DAILY. *TR”

AS I WAS SLOWING THE ROAD BECAME EXTREMELY BUMPY AND MY BRAKES ALL OF A SUDDEN FELT LIKE I WAS SLIDING OR FLOATING EVEN THOUGH I HAD THE PEDAL DEPRESSED.

“I KEEP HEARING ABOUT PRIUS BRAKE PROBLEMS ON 2010 MODELS BUT MY 2009 HAS THE SAME PROBLEM. I READ THIS IN AN ARTICLE ONLINE AND REALIZED THAT MY 2009 MODEL HAS THE BRAKING PROBLEM AS THE 2010 MODEL.

THEN, I INADVERTENTLY GO OVER A BUMP IN THE ROAD AND THE PRIUS LUNGES FORWARD. I HAD TO IMMEDIATELY SLAM HARD ON THE BRAKES IN ORDER TO KEEP THE CAR FROM GOING INTO THE INTERSECTION.

“TL*THE CONTACT OWNS A 2009 TOYOTA PRIUS. WHILE DRIVING 5 MPH TOWARD A STOP SIGN AND APPLYING THE BRAKES, THE VEHICLE FAILED TO STOP. THE TRACTION CONTROL LIGHT ILLUMINATED AS SOON AS SHE REMOVED HER FOOT FROM THE BRAKE PEDAL. WHEN THE LIGHT WAS NOT ILLUMINATED, THE BRAKES FUNCTIONED NORMALLY. THE FAILURE MILEAGE WAS 50. THE CURRENT MILEAGE WAS 33,000.”
