NHTSA Complaint #10305558 — 2006 TOYOTA PRIUS

I WOULD LIKE TO MAKE THE AGENCY AWARE OF MY EXPERIENCE WITH THE TRACTION CONTROL SYSTEM ON MY 2006 TOYOTA PRIUS. I UNDERSTAND THAT IT IS BEING INVESTIGATED FOR THE 2010 MODEL BUT I HAVE VERY SIMILAR ISSUES WITH MY 2006. THIS IS AN ONGOING ISSUE AND OCCURS REGULARLY FROM TIME TO TIME (AND HAS SINCE I PURCHASED THE VEHICLE NEW). WHEN PASSING OVER ROAD SURFACES THAT CAUSE THE TRACTION CONTROL SYSTEM ON THE VEHICLE TO ACTIVATE (WET ROAD, GRAVEL, POT HOLE, SNOW, ETC.), BRAKING AND ACCELERATION CONTROL IS TEMPORARILY LOST. THIS LOSS OF CONTROL PERSISTS FOR 1-5 SECONDS WHEN BRAKING, AND INDEFINITELY WHEN TRYING TO ACCELERATE (I.E. WHEN ON SNOW). BRAKING DISTANCE IS CLEARLY INCREASED, AS THE VEHICLE DOES NOT APPLY THE BRAKES AT ALL. I HAVE HAD SEVERAL INCIDENTS WHERE I HAD MAINTAINED A SAFE FOLLOWING DISTANCE, BUT NEARLY RAN INTO CARS STOPPING IN FRONT OF ME (DUE TO MY VEHICLE NOT BRAKING APPROPRIATELY). MERGING IS ALSO AN ISSUE AT TIMES, AS IS ACCELERATING (INTO TRAFFIC OR OUT OF A HAZARDOUS SITUATION ON SNOWY/WET ROADS). I FEEL THAT THE BEST SOLUTION WOULD BE THE ABILITY TO DEACTIVATE THE TRACTION CONTROL SYSTEM. UNFORTUNATELY TOYOTA IS NOT CURRENTLY OFFERING A WAY TO DO THIS. *TR
