NHTSA Complaint #10321196 — 2007 TOYOTA PRIUS

I NOTICED IN THE LAST FEW MONTHS THAT THE "SLIPPERY" SIGN ON MY PRIUS 2007 CAME ON MANY TIMES EVEN UNDER VERY SAFE ROAD CONDITIONS. FOR EXAMPLE, WHEN I DID A RIGHT TURN SLOWLY, THE "SLIPPERY" SIGN WOULD COME ON. ON FEBRUARY 26, 2010. I WAS DRIVING MY CAR WHEN IT STARTED TO SLEET. ALL OF A SUDDEN, MY CAR LOST CONTROL AND STARTED TO SPIN UNTIL IT HIT THE SNOW BANK ON THE ROAD SIDE. IN THE FOLLOWING WEEK, THE CAR SLIPPED TWICE WHEN I APPROACHED STOP SIGNS SLOWLY AND APPLIED BRAKE LIGHTLY. WE EXAMINED THE REAR TIRES WHICH WERE THE ORIGINAL TIRES WITH 48,000 MILES ON AND THE MARKINGS WERE MOSTLY WORN OUT. I WOULD ALSO WANT TO POINT OUT THAT THESE OLD TIRES PASSED INSPECTION ON THE SAME DAY OF THE ACCIDENT AND WE JUST CHANGED THE TIRES HOPING TO IMPROVE THE TRACTION. AFTER THE TIRES WERE CHANGED ON MARCH 6, 2010, IT SLIPPED ONCE IN THE FOLLOWING TWO WEEKS UNDER THE SAME SITUATION WHEN I APPROACHED A STOP SIGN SLOWLY AND APPLIED BRAKE LIGHTLY. THE ROAD CONDITIONS WERE ALL PERFECT WHEN THESE 3 SLIPPAGES HAPPENED AFTER FEB. 26, 2010. I HAVE READ SOME ARTICLES(CONSUMERAFFAIRS.COM) AND CHAT ROOMS(PRIUSCHAT.COM) ONLINE AND FOUND QUITE A FEW SIMILAR EXPERIENCES FROM OTHER PRIUS DRIVERS. *TR
