NHTSA Complaint #10306741 — 2009 TOYOTA PRIUS

EVERY DAY I ENCOUNTER A LARGE POT HOLE ON MY WAY TO WORK. IT IS ABOUT 20 FEET FROM A STOP SIGN, SO AT THIS POINT I AM ALREADY DRIVING SLOW AND BRAKING. HOWEVER, WHEN THE ONE WHEEL DIPS INTO THE HOLE, THE YELLOW TRACTION SYSTEM LIGHT COMES ON, AND I FEEL WHAT COULD BE A SLIGHT LOSS IN BRAKING, AS IF THE CAR IS COASTING FOR A SPLIT SECOND (VERSUS BRAKING/SLOWING) OR PERHAPS ACCELERATING FORWARD. THE CAR/SYSTEM RECOVERS AS SOON AS ALL WHEELS PASS THE POTHOLE. NOT HAVING HAD A TRACTION CONTROL SYSTEM PRIOR TO THIS CAR, I DIDN'T KNOW WHAT WAS NORMAL SO I DIDN'T PURSUE IT, BUT I KNOW I DON'T LIKE HOW IT FEELS! THIS HAS BEEN HAPPENING EVERY TIME I DRIVE OVER THAT POTHOLE SINCE I BOUGHT THE CAR. LUCKILY THEY JUST PAVED THE HOLE LAST MONTH FINALLY. OTHERWISE I TRY TO AVOID ROUGH ROADS AS A MATTER OF COURSE. PERHAPS A RELATED PROBLEM IS WHEN TRYING TO GO UP AN ICY/SLUSHY SLOPE AND THE TRACTION CONTROL SHUTS OFF THE WHEELS TO KEEP THEM FROM SLIPPING/SPINNING. SINCE I LIVE ON A HILL, THIS MAKES WINTER ESPECIALLY STRESSFUL AND MAKES ME FEARFUL OF DRIVING TO FROM WORK AND ENCOUNTERING EVEN A SLIGHT INCLINE THAT IS NOT PLOWED OR SALTED --WHAT IF THE CAR STOPPED AND I GOT HIT? TOYOTA SAYS THIS IS "NORMAL" TO KEEP THE ELECTRIC ENGINE FROM BEING OVER STRESSED OR SOME SUCH THING. *TR
