NHTSA Complaint #10457152 — 2011 TOYOTA PRIUS

STARTED CAR AFTER PROLONGED PERIOD OF COLD SOAK (PARKED FOR ONE WEEK OUTSIDE IN TEMPERATURES AROUND THE FREEZING MARK). ENGINE EXHIBITED A LOUD KNOCK/RATTLE AND HAD A DELAYED THROTTLE RESPONSE AS I WAS PULLING OUT ONTO THE STREET. HAD TO SHUT ENGINE DOWN (WITH VEHICLE LOCATED IN STREET, SAFETY CONCERN) TO STOP LOUD KNOCK AND RE-START ENGINE. RATTLE/KNOCK HAD DISAPPEARED. TOYOTA DEALERSHIP WHEN PRESENTED WITH ISSUE AND TOYOTA ISSUED TSB (T-SB 0012-10) ON THIS VERY ISSUE DECLINED TO PERFORM NECESSARY WORK SINCE THEY WERE NOT ABLE TO "RECREATE" THE ISSUE. I EXPLAINED THAT THIS ONLY HAPPENED ONCE AND TO REPLICATE THEY WOULD NEED TO PARK IT IN THE SAME CONDITIONS FOR A WEEK. I CANNOT LEAVE MY CAR WITH THEM FOR THIS LONG AND THEREFORE THIS IS AN UNREASONABLE REQUEST. MULTIPLE OWNERS HAVE EXPERIENCED THIS PROBLEM (AS A QUICK SEARCH ON YOUTUBE WILL CONFIRM) YET TOYOTA IS DENYING TO FIX THIS. *JS
