NHTSA Complaint #10352755 — 2005 TOYOTA PRIUS

I FIRST REPORTED THIS TO TOYOTA MARCH 10, 2010. I DID SO AFTER TALKING WITH A COWORKER WHO HAD A 2010 PRIUS. I HAVE A 2005 PRIUS. WE BOTH EXPERIENCED THE SAME THING. THEREFORE, I FIGURED I SHOULD TAKE IT MORE SERIOUS. THE TOYOTA'S SAFETY INCIDENT NUMBER IS [XXX] . WHEN GOING OVER BUMPS AND HITTING THE BREAKS I NOTICE THAT INSTEAD OF IMMEDIATELY SLOWING THE CAR DOWN, THE CAR SEEMS TO EITHER NOT SLOW AT ALL AND SEEMS TO ACCELERATE. KNOWING THAT GOING OVER BUMPS CAN CAUSE A TIRE TO TEMPORARILY LOOSE CONTACT WITH THE ROAD SURFACE AND THAT CARS CAN ELECTRONICALLY TRANSFER DRIVE FROM A TIRE THAT LOOSES CONTACT WITH THE SURFACE TO THE OTHER WHEEL, THERE MAY BE MIXED SIGNALS HAPPENING. THE BRAKES TELLING THE CAR TO STOP, THE TRACTION CONTROL TELLING THE ACCELERATION TO TRANSFER. IT SEEMS THE ACCELERATION IS TAKING PRECEDENCE. REGARDLESS, THIS SEEMS THAT IT COULD CAUSE A PROBLEM IF ON A BUMPY ROAD SURFACE OR A POT HOLE OR SOMETHING AND A CAR STOPS INFRONT OF ME OR A KID RUNS INTO THE STREET OR FOR SOME OTHER REASON I NEED TO STOP. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). *TR
