2009 TOYOTA PRIUS Complaints

TL*THE CONTACT OWNS A 2009 TOYOTA PRIUS. WHILE DRIVING AT 35 MPH APPROACHING AN INTERSECTION, THE CONTACT DEPRESSED THE BRAKE PEDAL BUT WHEN THE VEHICLE WENT OVER A BUMP IN THE ROAD, IT DID NOT SLOW DOWN. THE CONTACT HAD TO APPLY MORE PRESSURE TO THE BRAKES TO SLOW THE VEHICLE DOWN. THE VEHICLE WAS TAKEN TO AN AUTHORIZED DEALERSHIP BUT THE DEALER COULD NOT DUPLICATE THE FAILURE. THE FAILURE OCCURRED AGAIN AFTER THE CONTACT PICKED UP THE VEHICLE FROM THE DEALERSHIP. THE FAILURE MILEAGE WAS APPROXIMATELY 11,400. THE CURRENT MILEAGE WAS 11,634.

INCONSISTENT BRAKE FEEL ON ROUGH OR WET SURFACES. THOUGH BRAKE PEDAL IS DEPRESSED, BRAKES DON'T FEEL LIKE THEY ARE ENGAGING PROPERLY, IT FEELS LIKE A VIOLENT SHUDDER. RECENTLY, ON WET PAVEMENT I NARROWLY AVOIDED HITTING THE CAR IN FRONT OF ME WHEN I HAD TO STOP SUDDENLY AND THE BRAKES TOOK MUCH TOO LONG TO STOP THE VEHICLE. *TR

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

2009 PRIUS MODEL1220 A 2 EXPERIENCES WHERE CAR SEEMED TO "SURGE" WHEN BRAKES APPLIED IN TRAFFIC. ONLY LASTED SECONDS BUT DISCONCERTING. ABS DID ENGAGE INITIALLY (FELT PULSING). TOOK CAR TO DEALERSHIP 5/17 AFTER FIRST EPISODE. NOTHING FOUND WRONG; TECH COULD NOT DUPLICATE PROBLEM. HAD SECOND EXPERIENCE 5/21. *TR

IT IS A RECURRING INCIDENT/PROBLEM WITH MY 2009 TOYOTA PRIUS. BRAKING AT THE SAME TIME ONE IS GOING OVER A BUMP IN THE ROAD OR DURING INTERMITTENT SLIPPERY CONDITIONS. WHEN BRAKING AT THE SAME TIME THE CAR IS GOING OVER A MODERATELY ABRUPT BUMP OR PARKINGLOT DRIVEWAY ENTRANCE THE ANTI-LOCK BRAKING ENGAGES BUT THERE APPEARS TO BE DELAY - POSSIBLY IN CONNECTION WITH THE SWITCHING FROM THE REGENERATIVE BRAKE MECHANISM - CAUSING THE SENSATION THAT THE BRAKES HAVE FAILED FOR ABOUT 1 SECOND OR 2 - QUITE A DISCONCERTING FEELING AND CONCERN THAT IS POTENTIALLY DANGEROUS IF THE SAME ROAD CONDITIONS WERE PRESENT DURING A PANIC STOP. DURING INTERMITTENT SLIPPERY CONDITIONS - E.G. SNOW OVER THE ROAD, PARTIALLY PLOWED SNOW OR ICY CONDITIONS - THE ANTI-LOCK BRAKING/TRACTION CONTROL IS OVER-ACTIVE, CUTTING POWER ABRUPTLY TO ONE WHEEL THEN THE OTHER CAUSING A WHIPPING ACTION FROM SIDE-TO-SIDE. THIS RANGES FROM ANNOYING TO TERRIFYING INCLUDING ONE INCIDENT THAT THE CAR SPUN OUT 3 TIMES ON ONE SECTION OF A RURAL SNOWY ROAD - FORTUNATELY NO ON-COMING TRAFFIC WAS PRESENT AND THE CAR DID NOT GO INTO THE DITCH. WHEN THE DEALER WAS ASKED ABOUT THESE TENDENCIES THEY STATED THAT THIS WAS NORMAL - SO NO ADJUSTMENT TO A PART OR SOFTWARE HAS BEEN ABLE TO BE MADE. *TR

WHEN BRAKING ON A BUMPY SURFACE, THE CAR BRAKES SEEM TO DISENGAGE FOR A SECOND AND THE CAR SHOOTS FORWARD. THE LAST TIME THIS HAPPENED I WAS GOING DOWN A HILL AT AN INTERSECTION AND THE CAR WENT AROUND THE CORNER MUCH FASTER THAN I WOULD HAVE LIKED. *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

TOYOTA 2009 PRIUS LOSES BRAKES TEMPORARILY WHEN GOING OVER BUMPS IN THE ROAD. *TR

2009 PRIUS, ON THREE OCCASIONS I EXPERIENCED A SLIGHT HESITATION IN THE BRAKING OF THIS CAR. I EMAILED TOYOTA ABOUT THE PROBLEM ON 2/15/2010, AND BIB NOT RECEIVE A ANSWER UNTIL 5/10/2010. I MADE AN APPOINTMENT WITH THE LOCAL DEALERSHIP BEFORE I RECEIVED THEIR ANSWER ON 5/10. THE LOCAL DEALER SAID THEY DID NOT FIND A PROBLEM OR ANY BRAKE ERROR ON THE COMPUTER. WHY SHOULD IT TAKE SO LONG TO ANSWER MY EMAIL AND I STILL HAVE NO SOLUTION TO MY BRAKING TROUBLES. *TR
