NHTSA Complaint #10308430 — 2005 TOYOTA PRIUS

I OWN A 2005 PRIUS, BOUGHT NEW. I NOW HAVE 130,000 MILES ON IT. IT HAS BEEN SERVICED AND MAINTAINED AT SCHEDULED INTERVALS, MOSTLY BY A TOYOTA DEALER. #1: I HAVE COMPLAINED TO THE DEALER SINCE THE FIRST WINTER THAT I BOUGHT THE CAR THAT THE "TRACTION CONTROL SYSTEM" IS DANGEROUS IN BAD WEATHER CONDITIONS. WHENEVER THE ROAD IS SLIPPERY, IF THE CAR SENSES WHEELSPIN, IT CUTS POWER TO THE ENGINE. THIS IS SCARY IF YOU'RE PULLING OUT INTO TRAFFIC ON A RAINY DAY, AS THE CAR WILL SOMETIMES JUST QUIT RUNNING FOR A SECOND, LEAVING YOU VULNERABLE TO ONCOMING TRAFFIC. SNOW IS FAR WORSE. I LIVE ON A HILLY ROAD. IF IT'S SNOWY THE CAR WILL SLOW DOWN, AND SIMPLY STOP TRYING TO MOVE FORWARD ON THE FIRST STEEP SLOPE I COME TO. IT DOESN'T MATTER HOW HARD I MASH ON THE ACCELERATOR, OR IF I BACK OFF AND TRY AGAIN, THE CAR WILL NOT ATTEMPT TO MOVE. ONCE THE CAR STOPS MOVING FORWARD IT BEGINS TO SLIDE BACKWARDS, AND CONTROL IS TOTALLY LOST. I WAS NEARLY KILLED THE FIRST TIME THIS HAPPENED (IN ABOUT ONE INCH OF SNOW) AS MY CAR EVENTUALLY SLIPPED SIDEWAYS ACROSS THE ONCOMING TRAFFIC LANE. AN SUV CAME DOWN THE HILL AND NEARLY BROADSIDED ME BEFORE I WAS ABLE TO GET MY CAR TURNED BACK DOWN THE HILL. (MY CAR WAS EQUIPPED WITH AGGRESSIVE SNOW TIRES AT THE TIME.) EVER SINCE THEN, IF I'M COMING HOME FROM WORK IN THE SNOW, I LEAVE MY CAR IN THE SHOPPING CENTER AT THE BOTTOM OF THE HILL AND CALL MY HUSBAND, WHO PICKS ME UP WITH HIS FORD BRONCO. # 2: ANTI-LOCK BRAKING. THE 2010 PRIUS'S AREN'T THE ONLY ONES WITH PROBLEMS; MINE DOES THE SAME THING. IF I'M BRAKING ON A BUMPY STRETCH OF ROAD OR OVER A MANHOLE COVER IN THE RAIN, THE CAR WILL CUT POWER TO THE BRAKES, CAUSING THE CAR TO FEEL LIKE IT'S SURGING FORWARD. AGAIN THIS PROBLEM IS MUCH WORSE IN THE SNOW. GOING DOWNHILL ON A SNOWY, SLIPPERY HILL THE ANTI-LOCK BRAKES REPEATEDLY CUT BRAKING POWER, WHICH ACTUALLY CAUSES THE CAR TO ACCELERATE TO UNSAFE SPEEDS. MY DEALER TELLS ME THAT THIS IS HOW THE CAR WORKS, AND NOTHING CAN BE DOME TO CORRECT IT. *TR
